The role of accessibility policies and other determinants of health care provision in the initial prognosis of malignant melanoma: a cross-sectional study.

Background: The prognostic benefit of health care service provision and delivery policies for patients with malignant melanoma (MM) is not yet clear.

Objective: To analyze the role of health care provision determinants in the initial prognosis of MM.

Methods: A multicenter cross-sectional study was conducted at 14 public hospitals and recruited 3550 patients with MM between 2000 and 2009.

Merkel cell carcinoma with sarcomatous differentiation: is it a poor prognostic factor?

Background: Poor prognostic factors in Merkel cell carcinoma include male sex, advanced stage at diagnosis, large tumor size (>5 mm), diffuse growth pattern, heavy lymphocytic infiltrate, and high mitotic rate. To date only six cases of Merkel cell carcinoma with sarcomatous or pseudosarcomatous differentiation and poor prognosis have been documented.

Methods: We present a new case of Merkel cell carcinoma with sarcomatous differentiation.

Two cases of dermatomyofibroma (plaque-like dermal fibromatosis).

Background: Dermatomyofibroma is a rare but distinct benign cutaneous mesenchymal neoplasm of fibroblastic/myofibroblastic differentiation. It is more common in adolescents and young adults, with a female preponderance. In most cases, the lesions are asymptomatic and small, measuring from 10 to 20 mm.

Lupus erythematosus-like lesions by voriconazole in an infant with chronic granulomatous disease.

We report the first case of lupus-like lesions in an infant with chronic granulomatous disease during the treatment with voriconazole for chronic invasive aspergillosis. The lesions disappeared with termination of the treatment.
