Report of a case: primary mucinous carcinoma of the skin.

Primary mucinous carcinoma of the skin is an extremely rare adnexal tumor that is thought to originate from eccrine sweat glands. The neoplasm usually arises on the head and neck, with the most commonly involved area being the periorbital region. The tumor is typically a solitary, asymptomatic nodule, cyst, or ulcer that is slow growing with low metastatic potential.

Congenital Volkmann ischemic contracture: a case report.

Congenital Volkmann ischemic contracture is a rare condition in which a neonate presents with an ulcerated forearm, necrotic subcutaneous tissue, nerve palsy, and muscular necrosis. We report a case of a 1-day-old infant who presented with an ulceration of the left forearm noted at delivery combined with decreased motor function of the left distal forearm. Histologic examination of the ulceration revealed findings of subcutaneous fat necrosis of the newborn.

Ulcerative sarcoidosis in the legs with granulomatous vasculitis.

We present a case of a patient with pulmonary sarcoidosis who developed ulcerative sarcoidosis with granulomatous vasculitis on the lower legs. Ulceration is a rare presentation for sarcoidosis and this case gives further evidence that an underlying vasculitis may be an aetiological factor. Granulomatous vasculitis, classically associated with Wegener's granulomatosis, lymphomatoid granulomatosis, or Churg-Strauss syndrome, is also commonly described in pulmonary sarcoidosis.

Nephrogenic fibrosing dermopathy in a patient with systemic lupus erythematosus and acute lupus nephritis.

Nephrogenic fibrosing dermopathy is a recently recognized skin disorder similar in appearance to scleromyxedema but without the systemic involvement. We describe a 14-year-old girl with new-onset systemic lupus erythematosus and acute lupus nephritis who developed on the lower extremities confluent hyperpigmented, woody, indurated plaques that contained groups of coalescing erythematous papules. Nephrogenic fibrosing dermopathy was diagnosed histologically.

Topical imiquimod as an adjuvant to laser removal of mature tattoos in an animal model.

Background: Lasers are a commonly employed method of tattoo removal; however, numerous treatments are often needed and laser treatment may fail to eliminate the tattoo completely. It has been shown in animal studies that topical application of imiquimod cream, alone, fades tattoos. It is suspected that the combination of both imiquimod and laser treatment will result in enhanced tattoo pigment clearance.
