Since 1967, about 40 cases of digital necrosis associated with neoplasia have been reported. We report a new case of digital necrosis associated with an ovarian carcinoma and with a lupus-like syndrome. Immunologic cross-reactivity to tumoral antigen could explain the lupus-like syndrome.

Perineal localization of liposarcoma is extremely rare among all localization of soft tissue sarcoma. We report the case of 33-year-old man presenting a large perineal swelling. Throughout this case, we bring new insights into the surgical management difficulty of this tumor and we review the place of adjuvant therapy and prognosis factors.
