  4. Varicella-Zoster Virus Infection: Close-Up

    Varicella-zoster virus infection: herpes zoster with cluster of grouped vesicles. Grouped and confluent vesicles surrounding erythema on the chest wall.

  5. Nevus Depigmentosus

    Nevus depigmentosus (achromicus). These are localized areas of hypopigmentation that are usually present at birth. The lesions may be irregular in size and shape and occasionally follow a linear or segmental pattern. Electron microscopic study of these areas suggests that melanosomes are not being transferred from melanocytes into surrounding keratinocytes. There are no associated abnormalities.

  6. Acanthosis Nigricans

    Acanthosis nigricans. This is a descriptive term for a velvety or verrucous brown-to-black area of hyperkeratosis. The axilla and posterior are the most common locations, but lesions are also seen on the anterior neck and in the groin. Less commonly, there is involvement in the antecubital and popliteal fossae, on the knuckles, and in other, nonflexural areas. Onset may occur during childhood or adult life. The histologic pattern is that of hyperkeratosis and papillomatosis; the brownish discoloration seems to be caused by these surface changes rather than by any local increase in the amount of melanin. Illustrated here are lesions of acanthosis nigricans on the anterior neck and in the axilla.

  7. Actinic Keratosis (Solar Keratosis)

    Actinic keratoses are lesions on the outer skin layer caused by too much exposure to the ultraviolet rays of sunlight. They are also the beginnings of skin cancer, most often appearing after age 40.

  8. Hand Foot Mouth Disease on Hand

    Hand-foot-mouth disease. This common and benign viral disease of childhood is usually caused by the A16 strain of coxsackievirus, although other strains of the same virus have been implicated. It most often occurs in late summer and early fall. The prodrome consists of low-grade fever and malaise. Shortly thereafter, vesicular lesions arise on the soft palate, tongue, buccal mucosa, and uvula. The lips are usually spared. Occasionally, these lesions may be painful and cause some difficulty in eating. The cutaneous lesions develop 1 or 2 days after those in the mouth. They consist of asymptomatic round or oval vesiculopustules that evolve into superficial erosions. The edges of the palms and soles are a favored location.

  10. Geographic Tongue

    Geographic tongue. There is a peculiar condition of the tongue that takes the form of denudations of the lingual surface in patches of redness that shift in position from time to time over hours and days. The cause of the condition is not known; there may be some relationship to psoriasis. No treatment is effective. The condition is largely asymptomatic except for slight tingling when sharp food is taken.
