[Cutaneous and subcutaneous sarcomas]

Cutaneous sarcomas are uncommon tumors presenting many histological types. The diagnosis is based on pathological, immunohistochemical and sometimes ultrastructural studies. The development of cytogenetic and molecular analysis may constitute an additional aid to the diagnosis and classification. Prognosis and therapeutic strategies are established on the basis of various criteria using different types of staging and grading, but these classifications have not yet been standardized. The rarity of cutaneous sarcoma, and the diversity of clinical presentations account for the difficulties of management, which requires a multidisciplinary approach.
