Histopathological diagnosis of cutaneous vascular sarcomas.

Cutaneous sarcomas represent a heterogeneous group of mesenchymal lesions. This study investigates the histopathological and immunohistochemical features in different cases of angiosarcoma and Kaposi's sarcoma (cutaneous vascular sarcomas), which are representative for medical practice. The clinical-histopathological-immunohistochemical correlations render possible the differential diagnosis and a proper treatment can be applied to obtain a favorable prognosis.
