Syringocystadenoma papilliferum usually arises in the head and neck region. Linear lesions occurring in other locations are rare. We report such a case occurring on the thigh, documented by multiple biopsy specimens. The case is discussed in the context of other adnexal tumors that may form linear arrangements.

Miliaria crystallina is characterized by intracorneal or subcorneal, 1 to 2 mm, clear, noninflammatory vesicles that typically appear in crops after a severe sunburn or during a febrile illness. They frequently occur in neonates, most likely due to lack of maturation of the sweat duct during the first few days following birth, but are rarely present at delivery. We describe here a patient with extensive miliaria crystallina that was present at birth and review possible theories of the pathogenesis of these lesions.
Bipolaris spicifera is a dematiaceous fungus that has rarely been reported to cause cutaneous infection in humans. A patient with leukemia was examined for a non-healing ulcer on her leg that developed following minor trauma. Histopathologic study revealed groups of nonpigmented, septate fungal hyphae located predominantly in the necrotic ulcer base. Cultures of a biopsy specimen yielded colonies that were gray to black with a black reverse. Microscopic examination revealed dematiaceous, straight, oblong conidia consistent with B spicifera. The ulcer was successfully treated with surgical excision, skin graft, and amphotericin B.
The acquired immunodeficiency syndrome (AIDS) in children is now known to be a clinical entity separate and distinct from AIDS in adults. In this article we present a review of the recent literature describing the history, definitions, epidemiology, differential diagnosis, and immunologic and clinical features of pediatric AIDS. Special emphasis is placed on the cutaneous manifestations of human immunodeficiency virus infection in children, which, to date, have not been the subject of a comprehensive review.
