What is Lipoma?

A lipoma is a benign tumor of the fat cells in a slim, fibrous capsule positioned just beneath the skin. It is acknowledged as the most common type of noncancerous soft tissue tumor. Lipomas can arise at any age, but these growths are most common in adult individuals aged 40 to 60 years old and very rare to occur in children.

The primary etiology is not yet established. A genetic involvement is possible which involves a gene rearrangement of chromosome 12. Assumption exists concerning a feasible association between blunt blow trauma and subsequent growth of lipoma.

Most of the lipomas are small, usually about 1 cm to 3 cm in diameter but can increase to sizes over and above 6 cm. But in most of the cases, the growth remains the same size over years or grows gradually. They are usually painless and have a soft, rubbery texture. A lipoma is easy to recognize as it moves promptly with minor finger pressure. They could emerge almost anywhere but these dome-shaped growths are most frequent to appear on the trunk, neck, shoulder, armpits, upper thigh and arms.

Generally, lipomas need not to be removed. Treatment is not necessary as lipomas are not cancerous. If in case the growth becomes painful and sore, cyclically gets to be infected or inflamed, empties an offensive-smelling discharge, expands in dimension or becomes cosmetically unappealing, a surgical removal is considered necessary. Treatment selections aside from surgical removal include the use of steroid injections to shrink the tumor and liposuction to remove fatty lumps.

What is Acne?

Acne is a skin condition characterized by minor, although infrequently serious, skin eruptions due to inflammation around the sebaceous glands. It is most prominent on the face, chest, arms and back. Roughly about 85% of all people have acne outbreaks in some point in their lives.

Normally, the sebaceous glands produce a fatty, oily substance known as sebum, to protect and lubricate the skin. Acne results when the sebum flow is obstructed by dead skin cells, dried sebum or by bacteria. When there is a complete blockage, whitehead is produced. When the blockage is incomplete, blackhead results. In time, the clogged hair follicle enlarges, producing a bump. The follicles continue to enlarge until the walls rupture, permitting the normal skin bacteria to enter into the deeper layer of the skin. This will result to an inflammation. If the inflammation is close to the surface, this is termed as pustule, pimple for deeper inflammation and much deeper is called cyst.

Remove excess oil by regular gentle washing of the face with non-irritating unscented soaps. However, avoid vigorous washing and scrubbing as these may irritate the skin, making the acne worse. The use of over-the-counter preparations and topical solutions with benzoyl peroxide improves acne. If the acne is severe, dermatologists may prescribe topical and oral antibiotics. If the patient has drug-resistance to antibiotics, Accutane may be used as a substitute. If acne is fully managed, scars can be dealt with resurfacing derma procedure called dermabrasion. Except in severe cases where the skin eruption is widespread, normally acne is undisruptive and responds well to treatment.

What is Rosacea?

Rosacea is a very common erythematous, acne-like chronic dermatological condition that affects an estimated 45 million people worldwide.

Still, there is no particular cause that can sufficiently explain the pathogenesis of this disorder. It could be a pattern of genetic predisposition and environmental factors that has caused for it to arise. There is also a link connecting the condition to mites, sun exposure, medications that may cause blood vessel dilation, gastrointestinal diseases and Helicobacter pylori.

The major clinical symptoms of rosacea consist of red patches, development of telangiectases, which are small blood vessels that form just under the skin surface, diffuse facial redness, red cysts, and pink or irritated eyes. These manifestations tend appear, then disappear for weeks, months or even years and then reappear.

It frequently begins with a tendency to go red much more easily than other people do. In time, individuals may see irreversible redness on the face.

Characteristically, the nose can become red and bumpy and develop visible dilated superficial blood vessels. If left untreated, later stages can bring a disfiguring nasal condition called rhinophyma, a condition described by a bulbous, enlarged red nose and puffy cheeks.

Currently, rosacea isn’t regarded as a curable disorder, but it can usually be managed with appropriate, standard treatments. With lasers, intense pulse light, photodynamic therapy and isotretinoin made available, some cases of this condition may be drastically cleared for a long time.

Scabies Pictures

What is Scabies?

Conversationally established as the seven-year itch, Scabies is a highly communicable skin infection described by the eruptive lesions created from the skin excavations of the female itch mites called Sarcoptes scabiei. These eight-legged parasites are microscopic measuring around 0.33 to 0.45 mm but at times they are detectable as white pinpoints so a magnifying glass is of use. The parasite burrows underneath the epidermis to lay eggs and initiates an intense allergic irritation.

Scabies Causes

Any person can develop infection or re-infection since it is easily spread most often by prolonged, direct physical contact with infected individuals. The disease may also be transmitted from inanimate objects or by sexual contact. The time-span needed for the female itch mite to burrow on infected skin and lay eggs is within a day from the initial contact with the infected individual.

Scabies Symptoms

The clinical manifestations involve intense and unrelenting itchiness which becomes worse at night and after a hot shower. There are also superficial burrows which are often linear or s-shaped and come out as tiny, wavy, flushed, grayish or dark outlines on the skin surface, especially on the folds under the arms, around the wrists and between the fingers, and other moist areas. When larger areas of the body are involved and secondary infection is serious, hyperthermia, headache and body weakness will occur.

Scabies Treatment

This infection is more frequently observed in congested vicinities with insanitary living situations. It is a sign of poor hygiene. Care must be observed regarding effective preventive measures including good personal hygiene, regular changing of clean clothing, beddings and towels, exposing the linens used under the sun, washing used linens in hot water, general house cleaning and improving the sanitation of the environment. Stuffed toys can be wrapped up in a plastic bag for three days because the parasites cannot live on for too long being away from host’s skin. All rooms in the residence have got to be vacuumed and the bag should then be destroyed.

The medical management includes assessing the whole family of the infected individual before assuming any treatment, for as long as one member stays infected, others will potentially get the disease. Dermatologists treat this infection by recommending a medicated lotion to destroy the itch mites. People are instructed to apply permethrin cream from the neck down and let it remain on the skin during the night before it is washed off. This cream application is regularly repeated in a week. Benzyl benzoate emulsion and Kwell ointment are effective but should be limitedly applied entirely to the skin.

Shingles Pictures

What is Shingles?

Herpes zoster, also known as shingles is a highly contagious disease attributable to the reactivation of the dormant human herpes virus type 3 virus situated in the dorsal nerve root ganglion of the spinal nerves. The virus can migrate along the path of a nerve to the skin surface causing a rash of painful blisters. This disorder affects only those who once have had chicken pox and commonly hits over age 50. In a client with a history of chickenpox, shingles can occur at some immunocompromised situations. Prognosis is good except when the virus extends to central nervous system.

It is still undefined how and why reactivation happens. It is assumed that the virus reactivates when, as a result of old age, illness, cancer, stress or immunosuppressant medications, the immune system turns out to be too vulnerable to keep the virus in a state of dormancy. After viral reactivation, the chicken pox virus travels down the sensory nerve into the skin to cause shingles.

In early stages, there is a tingling, itching, lightning bolt sensation followed by pain on one side of the body. One to three days after the pain starts, a rash with raised, red lumps and blisters erupts on the skin surface following a dermatomal outline or a ray-like distribution as blisters follow the pathway of individual nerves. They start to become pustules, and then scabs form by 10 days.

Separate the infected person from others because exudates from the lesions hold the virus. Maintain standard precautions. Use an air mattress on the bed and keep the atmosphere cool. Never scratch the skin where the rash is located to avoid the risk of secondary infections and scarring. To soothe the blisters, render cool water compress to suppurating blisters for 20 minutes many times a day. In the early stage of the disease, antiviral drugs may be combined with a strong corticosteroid to speed up healing and diminish the extent of pain. In the most critical situations, blocking agents are given via injection to stop pain signals from reaching the brain.

What are Hives?

Hives are common skin disorders characterized by edematous plaques with severe itching. Classically, it appears as pallid red, raised, itchy bumps. Each hive remains for a few minutes to several hours before disappearing. For hours or days, clusters of these lesions may come, go, and return episodically. It can be acute when it persists less than six weeks or chronic when the sequence continues longer than six weeks. Acute urticaria accounts for the majority of the cases. Chronic urticaria is idiopathic in nature, rarely caused by an allergic reaction.

In urticaria, whether the activator is allergic or non-allergic, a complex release of inflammatory mediators is involved. One of the chemicals released from the cutaneous mast cells during the process is histamine, which causes escape of fluid from the superficial blood vessels.

Urticaria begins as red circular rashes and soon become pale and edematous which comes with an intense itching and burning sensation. Characteristically, hives rapidly change in size, moving anywhere from one are to another, disappearing and reappearing in matters of hours.

In the environment, numerous substances can cause hives including: medications, food, and physical agents which are aquagenic, stress-related, cholinergic, dermatographic, adrenergic, parasitic or temperamental.

Early identification and avoidance of the allergic triggers are the best ways to prevent another urticaria attack. If exposed to a trigger, have a preventive dose of antihistamine to inhibit hives from developing. Diphenhydramine is considered most effective non-sedating antihistamine. If the urticaria is severe, oral corticosteroids are given for short time only. Starch and colloid-type baths are used as comfort measures. In patients who experience angioedema of the respiratory tract, the doctor may counsel to bring a prescription of epinephrine.

Cellulitis Pictures

What is Cellulitis?

Cellulitis is the most familiar cause of limb swelling. The connective tissues are diffusely inflamed with serious inflammation of the dermal and subcutaneous layers of the skin. It happens when an entry point through the first line of skin barriers has been injured permitting the normal microflora or exogenous bacteria commonly the Group A Streptococcus and Staphylococcus to penetrate and release toxins in the tissues. This is non-contagious since the infection is limited to the deeper layers of the skin and the epidermis provides a cover over the infection.

The predisposing factors for cellulitis include bites, blistering, skin damage, severe acne, chicken pox, tinea pedis, tattooing, pruritic skin rash, recent surgical operation, dry skin, puncture wounds or in any ways that break the skin.

Old age, weakened immune system and diabetes are especially more at risk to contracting the disease than the general population. Because of the impairment of blood circulation in the legs leading to foot ulcers in diabetic patients, they are markedly prone to feet cellulitis. Poor management of blood glucose levels tolerates the bacteria to multiply at speed in the affected tissue and facilitates swift progression as infection goes through the lymph nodes and bloodstream.

This bacterial skin infection usually starts as a small area of inflammation that extends to neighboring skin areas. As the tender area begins to expand, the sick person develops hyperthermia, sometimes with chills and sweats, and swollen lymph nodes.

The affected individual is asked to elevate the involved area above the hear level. Every 2 to 4 hours, warm, moist packs are applied to the affected site. In mild cases of cellulitis, the treatment can be on an outpatient basis using oral antibiotic therapy. If severe, hospitalization is required and treated with an antibiotic intravenously with duration of 7 to 14 days.

Contact Dermatitis Pictures

Jun 20 2011 Published by admin under Uncategorized

What is Contact Dermatitis?

Contact dermatitis is a medical term for skin inflammation that results from exposure of the skin to an external chemical or physical substance, which can be an irritant or an allergen.

About 80% of the cases of contact dermatitis are caused by irritants. The inflammatory reaction is attributable to the direct effect of irritant substances like soaps, plants, solvent, latex, cosmetics, food, and detergents on the skin.

The remaining 20% of the cases are accounted to allergic contact dermatitis which is also the most prevalent type of immunotoxicity. In this case, the skin inflammation is caused by a hypersensitivity reaction acting via the interaction of the immune system’s immunoregulatory cytokines and T lymphocyte subpopulations to a specific substance. It begins with the chemical breaking through the skin. It binds to Langerhans’ cells and travel to lymph glands close by. Sensitization ends when the allergen has been introduced to T-lymphocytes which will produce memory cells to remember that specific allergen. A previous exposure to the substance is needed to provoke allergy. Succeeding exposure causes the T-lymphocytes to recognize the allergen and activates them, releasing inflammatory mediators to the site.

Formaldehyde, rubber, fragrances, nickel, topical medications, hair salon chemicals and some plants are the commonest allergens. In this case, there is a delay of the immune response between the first exposure and the consequent reaction.

Another difference between the two types of dermatitis is the extent of inflammation as manifested in the skin surface. Usually, allergic dermatitis is confined to an area where the trigger was actually in contact with the skin while in irritant, the skin inflammation is more widespread.

The common reaction is a red rash which appears immediately in irritant contact dermatitis while the rash brought by allergic contact dermatitis every so often emerges until 1 to 3 days following an allergen contact. Urticaria appears in a pattern where the skin was directly exposed to a trigger and worsens when the area is scratched.

To discard and inactivate most of the displeasing substance, clean the exposed skin with soap and cool water straight away after direct contact to an identified trigger. Lemon juice and vinegar which are weak acids can be applied to neutralize the effects of the chemical substances. Cold moist compresses are done for 30 minutes thrice a day if there is development of blisters. Aside from application of calamine lotion and cool colloidal baths, Diphenhydramine can be taken to relieve itching.

What is Tinea Versicolor?

Dermatomycosis furfuracea, also called as Tinea versicolor is a condition distinguished by a rash on the trunk and proximal extremities, majorly caused by Malassezia globosa. This yeast is naturally living on the human skin and only becomes disruptive under special circumstances, including high temperature, weakened immunity, and hormonal abnormalities. It is assumed that the yeast feeds on lipids on top of dead skin cells.

Generally, oval-shaped spots with sharp borders roughly about ¼ to 1 inch in diameter often come into the skin surface together to form a bigger patch. Frequently affected body areas are the back, upper arm, torso, lower legs, armpit, and could also be show on the face. There is an infrequent fine scaling of the skin which gives an external ash-like scale. During a strenuous activity or in warm days, the body temperature is elevated. Sometimes when there is an elevation of the body temperature, pin-prick itching is felt in the affected areas. The warmer the temperature, the worse it gets. The distressing itch stops once sweating begins.

Pigmentary alterations occur. The term versicolor presents the detail that it brings about color shifts to the involved skin by either becoming lighter or darker than the adjacent skin surfaces. Commonly, people who have dark complexion will have hypopigmentation, while those with lighter skin tone will have hyperpigmentation. These temporary discolorations are termed as sun fungus.

For the treatment of tinea versicolor, wash and dry the affected skin area. A thin layer of antifungal agents are applied to the skin two times a day for less than 2 weeks. Some doctors prescribe the most economical yet effective treatment which is selenium sulfide shampoo to be applied for 10-15 minutes before rinsing; done twice a week for about 2 to 4 weeks. In severe, massive and recurring cases, Nizoral pills will eliminate the fungus and relieve any itch.

Ringworm Pictures

Jun 19 2011 Published by admin under Uncategorized

What is Ringworm?

Ringworm or Dermatophytosis is a very common skin disease caused by several different fungal infections collectively known as tinea. The term ringworm originates from the early belief that the disease was caused by a parasitic worm which is untrue. The lifetime risk of an individual to develop this superficial fungal disease is between 20 to 30%.

Ringworm Symptoms

  • The infection causes flaking, ring-shaped, itchy red patches that develop on various parts that could erupt and ooze. The patches often have sharply-defined borders growing to nearly one inch crossways. They are frequently redder around the outside with clear tone in the middle. This forms the manifestation of a ring wherein the infection remains active.
  • There are hairless patches and scales on the scalp, and scratchy, scaling irritation under a beard.
  • Nails thicken, become discolored, crusty and rough and could even crumble.
  • There is dry scaling and fissuring of the skin between the toes.
  • The groin is a usual area of infection. Usually on the inner area of the upper thigh, scaly, red-brown patches develop.

Ringworm Causes

Naturally, bacteria and fungi live on our bodies. A number of these microorganisms are helpful while others are opportunistic, multiply in haste to form contagious diseases. When a specific fungus thrives and multiplies anywhere, ringworm arises. The mode of transmission is via direct skin-to-skin contact, and contact with inanimate, personal objects. Exposure to infected animals is one mode of transmission. In very uncommon cases, infection can be attributed to exposure to infected soil. If the soil does have ample nutrients, the fungus that causes ringworm in humans can survive for an extended period of time. Still, for a person to become infected in this mode, the individual would have to have prolonged contact with harshly contaminated soil or else the odds are thin.

Ringworm Treatment

Individuals with ringworm respond well to self-care treatment. They are advised to keep their affected skin as clean and dry as possible. If it starts to erupt, apply damp compress to clear out the area. Use OTC antifungal powders, creams and lotions especially those containing ketoconazole, clotrimazole, terbinafine and miconazole. These are generally used once or twice a day. Infection begins to disappear within a week. With continued application for the recommended amount of time will guarantee the total eradication of the fungal infection.

When there is a severe or persistent infection and OTC treatments fail, it may require treatment by a physician. Antifungal oral agents may be given.

If there is ring worm on the groin, the individual should wear cotton underwear and change it more than once per day. If there is athlete’s foot, change the socks frequently to keep the feet dry.
