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.

What is Seborrheic Keratosis?

Known also as Seborrheic verruca and senile wart, Seborrheic Keratosis is a noncancerous growth of idiopathic origin and is the most common benign tumor in older population.

The wart may just be single or may come in clusters of dozens and its size ranges from being tiny to larger than 1 inch in diameter. Usually, they come out as white to light tan and darken to brown or black as time goes by. At first, they are flat but as they grow thicker over time, they rise above the skin surface giving rise to a dome-shaped appearance. The characteristic feature of this skin condition is the waxy, stuck-on appearance, but their texture may become dry, rough and bumpy. When they start appearing on the face, they may become unsightly. This is asymptomatic. However, they can tingle, swell and hemorrhage easily.

The primary cause of Seborrheic Keratosis is yet undecided. Commonly affected are the sun-exposed areas such as the back, arms, face and neck, so perhaps, prolonged exposure to ultraviolet rays may play a role. The second factor is genetics. Some families have innate predisposition to have these multiple lesions.

After proper diagnosis, no treatment is necessary except in cases where it becomes irritated or unattractive. Remember also that there is no way to prevent new dark spots from forming. Picking at the lesion will just cause a small risk of a localized infection. If the tumor becomes terribly itchy or is irritated by clothing, a mild topical steroid cream can be used. Also, it can be removed by cryosurgery or freezing. If the lesion is small, it can be treated with light electrocautery while larger lesions can be removed by electrodessication and curettage, shave biopsy, or cryotherapy with liquid nitrogen. Except in patients with dark complexion, when properly performed, the removal of seborrheic keratoses will not cause much noticeable scarring.

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.

Pityriasis Rosea Pictures

What is Pityriasis Rosea?

Pityriasis rosea is a non-dangerous skin rash but inflicts considerable distress on some people. It typically starts with a solitary mother patch lesion, and then after 1 to 2 weeks, a generalized body rash lasting about six weeks follows.

The cause is undefined but it suggests a viral infection as the culprit based on its clinical presentation and immunologic reactions. As evidence shows, there is viral reactivation of human herpes virus-6 and HHV-7 but this is not consistent to some other cases because no antibodies were identified. Adding to the controversy is the fact that HHV-7 is commonly found in healthy people.

In most of the reported cases, an upper respiratory tract infection comes first. Then, a single elliptical, red herald patches around 2 to 10 cm. emerges characteristically on the abdomen. On occasions, the mother patch may come out on hidden areas like in the armpit for instance. 7 to 14 days after the herald patch appeared, large daughter patches of red, egg-shaped rash come out on the upper body and can also appear in the mouth. On rare cases, an inverse distribution of the rash occurs mostly on the extremities. Generally, the red patches stretches broadly across the chest going by the rib-line in a Christmas-tree distribution. Several days later, small circular patches appear on the back, neck and on the cheeks. The prognosis is good, with patients recovering completely for only a matter of weeks or in some cases up to six months.

There is no definitive prevention as the cause is still undetermined. Similar with common viral infections, preventive measures include proper hygiene, frequent hand washing, avoiding crowded places and contact to people who cough and sneeze.

This skin condition usually goes away without treatment Antihistamines and topical corticosteroids provide relief from itching and improve the appearance of the rash. Steroids however may cause the new skin to take longer to tone with the surrounding skin color. Use only soap with moisturizer. Exposure to direct sunlight for about 10 to 15 minutes a day can help the lesions resolve quickly.

Folliculitis Pictures

What is Folliculitis?

It is a common dermatological condition characterized by the appearance of numerous small red or pink lesions with accompanying red halo indicating inflammation in one or more hair follicles. The pus-filled, red lesions cause the skin to appear like a chicken skin. Any part of the skin can be affected; ten to one hundred small bumps may come out in the chest, back, scalp, underarms, groin, extremities, face and buttocks. Mild to moderate folliculitis may often involve itchiness. In more severe cases where the infection is deeper and affects the entire follicle, the problem is pain. Scratching off the top exposes a small locked in hair within.

When hair follicles are damaged by tension from uncomfortable clothing, follicular blockage or shaving, folliculitis begins. In the majority of cases, the damaged follicles become infected with Staphylococcus aureus.

On the whole, it may be cosmetically disturbing but it medically undisruptive. The prognosis is very good as it is an easily curable condition. Most cases may resolve suddenly without undergoing any medical treatment.

To prevent folliculitis, use the following self-care guidelines. Shave in the same direction of hair growth using electric razor and avoid trimming the irritated areas. Avoid tight, constrictive clothing. Washing personal items such as linens and towels frequently is important.

An effective measure to promote drainage of the infected follicles is the application of hot, moist compresses. Depending on the result of the bacterial culture, the physician may endorse the use of antibacterial wash and antibiotic pills. Antibiotics can be applied directly to the skin or taken per orem to control infection To prevent further damage to the hair follicles and infection avoid shaving the area but if it becomes necessary, use a clean, new razor blade or an electric razor each time.

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.

Lichen Planus Pictures

Jun 20 2011 Published by admin under Uncategorized

What is Lichen Planus?

Lichen planus is a common, chronic mucocutaneous disease that affects a wide area of the skin, tongue, genitalia, and oral mucosa.

The cause is still undefined. Some of the lichenoid reactions occur as hypersensitive reaction to certain medications, in such cases termed drug-induced lichenoid reactions. It is also thought to be caused by an anomalous immune reaction aggravated by Hepatitis C viral infection.

On top of the cutaneous eruption, lichen planus involves other parts like the mucous membrane, genitals, nails and the scalp. The classical manifestation is in a form of flat-topped papules or rashes which are shiny and violaceous. There is variation in size from 1 mm to greater than 1 cm in diameter. Wickham striae are regularly found on the papules which appear as fine, white lines.

The mouth is affected in 50% of the cases. Because of mucous membrane involvement, lesions are common on the tongue and in the buccal mucosa. These oral lesions are distinguished by painless gray or white streaks which outline a fern-like pattern on the violaceous skin. There are as well quite painful and persistent ulcers and scattered redness and shedding of the gums.

10% of lichen planus cases involve one or more nails. Affected nail plates are likely to be thin and could become grooved and uneven. There may be onycholysis wherein the nails grow dark, thicken and separate from the nail bed. The nails may drop, cease growing and may vanish completely.

The disease is self-limited and typically resolves in 8 to 12 months so the treatment is not always essential. If pruritus is worse, the physician may suggest an antihistamine. In mild cases of lichen planus, fluorinated topical steroids are used. A thin film should be rubbed accurately once a day and is terminated when the lesions have flattened. If the mouth is involved, steroid paste may be easier to apply. If the genitals are affected, hydrocortisone foam is prescribed. More intensive therapy involving systemic steroids like prednisone is needed to treat severe cases particularly those with mucous membrane involvement.

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

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.

Panniculitis

Panniculitis is a term for a wide category of disorders whose major characteristic is the chronic inflammation primarily contained in the subcutaneous tissue. Nodular fat necrosis is the other name for acute Panniculitis. The danger increases significantly if the individual is becoming more overweight. It is most often seen in the abdomen where fat rolls are common. Usually, it presents as erythematous swelling in the adipose tissue that may or may not be sore, that could ulcerate or heal with no scarring, and on palpation, may be soft or solid.

The hallmark sign of acute Panniculitis is the development of a sole or numerous crops of nodules in subcutaneous fat. Usually, the bumps are tender but not always. Rarely, an oily pus secretion is drained. A single lesion persists for about 1 week to 2 months before it entirely disappear. A discolored depressed mark may be present at the affected side.

Others may develop hyperthermia, abnormal liver function, bone marrow depression, bleeding tendencies, nodular pulmonary lesions and pancreatic disease.

Frequently, the classical treatment for Panniculitis is insufficient which includes topical creams, oral antibiotics and anti-inflammatory medications. Patients with particular types of this disorder may well respond to combined chemotherapy. I f this will be left untreated, the condition can go from bad to worse and begin to affect vital organs other than the subcutaneous tissues. It can readily shift into the connective tissues leading to increased chance of acquiring lupus.
