Subungual melanoma is a relatively rare variant of melanoma, accounting for 0.7-3.5% of all melanoma cases in the Caucasian population. Curiously, it occurs in 8-33% of cases in black, Asian, Native American and Hispanic populations, which generally face a substantially lower risk of melanoma. Herein the authors report the case ...

In recent years, the screening accuracy of clinical dermoscopy has increased in the early detection of evolving atypical melanocytic neoplasms. However, the most dramatic cases of human malignant melanomas (MM), i.e. the fast-growing neoplasms, usually escape the classical clinical criteria of MM. As a result, a number of puzzling cases ...

The occurrence of granulomatous reactions within lymph nodes that drain carcinomas is well known but uncommon. Even more rarely, granulomas may occur within the stroma of tumors. These lesions, called sarcoid-like reactions, commonly accompany carcinomas but are very rare in sarcomas. This study presents a case of classic Kaposi sarcoma ...

Undifferentiated sarcomas are primitive mesenchymal tumors that cannot be classified among standardized histopathologic entities. Whether they represent a homogeneous group with common histogenesis and clinical behavior or comprise a variety of tumors able to differentiate along specific maturative lineages is still debated. To identify prognostic and histogenetic markers, we analyzed ...
