RESUMO
Cutaneous metastasis of uterine cancer is rare and is often associated with late-stage disease. Most uterine malignancies are endometrial adenocarcinomas, but a small subset is uterine carcinosarcoma, also known as malignant mixed Mullerian tumors. Uterine carcinosarcomas are highly aggressive tumors with an average 5-year survival rate of 26%-34%. Metastases most commonly occur in the abdominal wall, lung, and bone. Cutaneous metastasis is exceedingly rare and may pose a diagnostic challenge. The authors report a 57-year-old woman with multiple subcutaneous nodules on the face and trunk. A biopsy revealed similar morphology and staining characteristics as the sarcomatous component of the primary uterine carcinosarcoma. Histopathological features and immunophenotypical characteristics of the metastatic tumor are detailed in comparison with the original tumor. A review of the literature is also provided.

Verrucous hemangioma represents a rare congenital vascular proliferation that may be mistaken for angiokeratoma. Histopathological examination of a deep biopsy is necessary to confirm the diagnosis of verrucous hemangioma based on its involvement of the deep dermis and subcutaneous tissue. We present two cases of verrucous hemangioma and discuss the clinicopathologic and immunohistochemical findings.

BACKGROUND: The incidence of melanoma is increasing in Caucasians and in Hispanic subgroups in California and Florida. There is a paucity of information regarding melanoma incidence, stage at diagnosis, and other patient and tumor factors among minority subgroups in the northeast USA. This report examines melanoma in non-Hispanic white, non-Hispanic black, and Hispanic residents of Connecticut. METHODS: Trends in age-adjusted melanoma incidence rates (1992-2007) and the corresponding annual percentage changes in rates were calculated for Connecticut residents by race and Hispanic ethnicity. The racial/ethnic variation was evaluated for a number of patient and tumor characteristics: gender, age at diagnosis, marital status, anatomic site, histology, ulceration, Breslow thickness, and stage at diagnosis. Statistical significance at the 95% level was assessed using confidence intervals (95% CIs) and Pearson's chi-squared tests. RESULTS: Between 1992 and 2007, melanoma incidence increased by 4.1% per year in non-Hispanic whites in Connecticut (95% CI 3.1-5.1%; P<0.05). Melanoma incidence remained relatively stable for Hispanics and non-Hispanic blacks over the same period. A significantly higher proportion of advanced (regional and distant) melanomas were diagnosed in non-Hispanic blacks (19.1%) and Hispanics (17.1%) than in non-Hispanic whites (8.7%) (P<0.001). CONCLUSIONS: A significantly higher proportion of advanced melanomas were diagnosed in non-Hispanic blacks and Hispanics than in non-Hispanic whites. There is a growing need to educate patients and healthcare providers of the necessity for skin cancer surveillance regardless of the race of the patient.
