RESUMO
Cutaneous metastases from internal malignancies in women overwhelmingly emanate from the breast and typically exhibit features of an adenocarcinoma, although other histopathologic patterns may also be seen. Neuroendocrine breast carcinoma represents an uncommon variant of mammary carcinoma with fewer than 40 cases of the small cell subcategory reported. As with other small cell carcinomas, they may exhibit Merkel cell-like features and appropriate diagnosis of these tumor deposits often turns on clinical history and an appropriate immunohistochemical profile. Herein, we report the first known patient with cutaneous metastases from a small cell neuroendocrine breast carcinoma.

Brown recluse spider bites (BRSB) cause a myriad of reactions ranging from local necrosis to potentially lethal systemic involvement. Envenomation may induce a generalized exanthem known clinically but not described histologically. We report a 49-year-old female who developed a generalized exanthem 24 hours after BRSB. The histopathology demonstrated a necrotizing vasculitis similar to that seen at an envenomation site but without epidermal necrosis. Loxoscelism should be considered in patients residing in endemic areas who present with a vasculitic exanthem.

In the last several years, amantadine has been increasingly prescribed for akinesia in Parkinson's disease and to combat fatigue associated with multiple sclerosis. Amantadine is a well-known medication involved in drug-induced livedo reticularis (LR), yet remains under-reported in the English literature. We describe 2 patients with amantadine livedo reticularis: one patient with multiple sclerosis had, previous to this eruption, tolerated 4 years of amantadine therapy without adverse reactions and another patient with Parkinson's disease who developed LR 1 month after starting amantadine.

OBJECTIVE: To determine physician preparation for performing the skin cancer examination (SCE). DESIGN: We evaluated medical students' observation, training, and practice of the SCE; hours spent in a dermatology clinic; and self-reported skill level for the SCE by a self-administered survey. PARTICIPANTS: Graduating students at 7 US medical schools during the 2002-2003 academic year. MAIN OUTCOME MEASURES: Percentages of students reporting SCE skill observation, training, and practice. RESULTS: Of 934 students, 659 (70.6%) completed surveys. Twenty-three percent of students had never observed an SCE, 26.7% had never been trained to perform an SCE, and 43.4% had never examined a patient for skin cancer. Only 28.2% rated themselves as somewhat or very skilled in the SCE. This rate dropped to 19.7% among 553 students who had not completed a dermatology elective. Compared with students without training, students who had been trained at least once in the SCE were 7 times more likely to rate themselves as being somewhat or very skilled in the SCE. Sixty-nine percent of students agreed that insufficient emphasis in their medical training was placed on learning about the SCE. CONCLUSIONS: This survey documents the need for more consistent training of medical students in SCE. Even brief curricular additions would augment students' perceived skill levels and improve practice patterns and competencies of future physicians. More frequent and improved SCEs might result in earlier detection of melanoma and nonmelanoma skin cancers by nondermatologists, with significant public health benefits.

BACKGROUND: Human immunodeficiency virus-associated eosinophilic folliculitis (HIV-EF) among homosexual men is a commonly reported dermatologic finding, while only 4 cases in HIV-positive women have been documented in the literature to date. This article describes 2 additional cases of HIV-EF in immunocompromised women and reviews the data on this condition. OBSERVATIONS: The diagnoses were made on the basis of clinical appearance and microscopic analysis of skin biopsies. The women were not receiving highly active antiretroviral therapy (HAART) and their CD4 cell counts were below 100/ micro L. CONCLUSIONS: As HIV prevalence continues to increase in the female population, more cases of HIV-EF will be seen among women. Because the etiology of HIV-EF remains elusive, no single treatment stands above the rest although several successful therapies have been demonstrated. However, HAART restores the proper T-cell milieu, which seems to improve the course of this disease.
