She reported sensation of gradual increase in a solid nodule, painless at palpation, with diffi cult mobilization. Exeresis was proceeded with diagnostic hypothesis of endometriosis. Microscopy revealed a mesenchymal neoplasia characterized by proliferation of monomorphic fusiform cells and storiform aspect characterizing the DFSP.DFSP must be remembered in the differential diagnosis of the affections of the inguinal region in gynecology because it represents a malignant neoplasia, although it’s rare.
