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.

BACKGROUND: HER-2/neu onco-protein is increasingly being recognized as a target for therapy in solid tumors, but data on its role in malignant melanoma is currently limited. Our study objective was to determine a relationship, if any, between HER-2/neu overexpression and malignant melanoma. PATIENTS AND METHODS: Overexpression of HER-2/neu was evaluated in patients with malignant melanoma by using immunchistochemistry (DAKO Hercep test) in 202 archival tissue specimens. RESULTS: Between 1991 and 2001, 202 subjects [109 males; (54%) and 93 females; (46%)] with malignant melanoma were studied. Interestingly, only 2 of the 202 patients (0.9%) with biopsy-proven malignant melanoma revealed HER-2/neu overexpression. CONCLUSION: The results of our large study indicate that the HER-2/neu onco-protein neither has a role in melanogenesis nor is a potential target for clinical trials with monoclonal antibody therapy. Thus, there is no role for HER-2/neu testing in patients with malignant melanoma.

BACKGROUND: HER-2/neu and c-kit (CD117) onco-protein are increasingly being recognized as targets for therapy in solid tumors, but data on their role in malignant melanoma is currently limited. We studied the prevalence of overexpression of HER-2/neu and c-Kit in 202 patients with malignant melanoma to evaluate a possible prognostic value of these molecular targets in malignant melanoma. METHODS: Overexpression of HER-2/neu and c-Kit was evaluated using immunohistochemical assays in 202 archival tissue specimens. RESULTS: Between 1991 and 2001, 202 subjects (109 males; 54% and 93 females; 46%) with malignant melanoma were studied with a mean age of 57 years (age range: 15-101 years). The most common histologic type was amelanotic melanoma (n = 62; 30.7%) followed by superficial spreading melanoma (n = 54; 26.7%). The depth of penetration of melanoma (Breslow thickness, pT Stage) ranged from 0.4 mm (stage pT1) to 8.0 mm (stage pT4A). Mean thickness was 2.6 mm (stage pT3A). The ECOG performance scores ranged from 0 to 3. Only 2 patients (0.9%) revealed HER-2/neu overexpression, whereas 46 (22.8%) revealed c-Kit overexpression. Multivariate analysis performed did not show a significant difference in survival between c-Kit positive and negative groups (p = 0.36). Interestingly, not only was c-Kit more likely to be overexpressed in the superficial spreading type, a preliminary association between the presence or absence of c-Kit overexpression and the existence of another second primary tumor was also observed. CONCLUSIONS: The results of our large study indicate that the HER-2/neu onco-protein neither has a role in melanogenesis nor is a potential target for clinical trials with monoclonal antibody therapy. This indicates there is no role for its testing in patients with malignant melanoma. Although c-Kit, expressed preferentially in the superficial spreading type, may not have prognostic value, it does have significant therapeutic implications as a molecular target warranting further investigation.
ABSTRACT
Two months after being started on Depakote (divalproex sodium: Abbott Laboratories Inc., Abbott Park, Illinois), a 57-year-old female noticed the development of a transverse yellow band on all 20 proximal nails that eventually led to complete nail plate discoloration. Six to eight weeks after discontinuation of Depakote, normalization of her proximal nail plates was noted. Other anticonvulsants such as phenytoin and lithium have been documented to lead to nail pigmentation. Although several dermatologic reactions to Depakote have been described, we are not aware of any reported cases of nail discoloration secondary to Depakote. While our patient did have a history of renal disease with azotemia, we find it highly unlikely to be a contributing factor secondary to the fact that our patient's abnormality did not present similar to the nail abnormalities of renal disease. In conclusion, we found the temporal relationship between Depakote initiation/discontinuation and the nail discoloration to be highly indicative of Depakote as the source.
