Dermatofibrosarcoma protuberans (DFSP) is a rare malignant neoplasia in gynecology, with probability of recurrence and low possibilities of metastasis. A 34-year-old patient after endometriosis treatment presented pain in the left inguinal region. She reported sensation of gradual increase in a solid nodule, painless at palpation, with difficult 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.

Axillary nodal metastasis is still the most important breast cancer prognostic factor. As in approximately 80% of the patients with tumors measuring less than 2 cm the axillary lymph nodes are negative, it has been proposed sentinel lymph node biopsy, reducing surgical morbidity in the patients with negative result. Recently, this technique has been widely used in Brazil, but there are two questions that need to be answered: what is the probability of a false-negative result (not diagnosing a positive lymph node) and if the understaging by false-negative result exposes the patient to the risk of axillary recurrence or even distant metastases, due to less effective surgical and adjuvant therapy. The literature shows that the false-negative rate varies from 5 to 10%, being the surgeon's experience the major factor that contributes to improved results. Although axillary relapse is rare, it is not yet possible to evaluate the long term effect of not removing positive lymph nodes, due to short follow-up. The recommendation is that sentinel lymph node biopsy should only be performed by surgeons with experience confirmed by a low false-negative rate.
