Leiomyosarcomas are malignant tumors that originate of the smooth muscle. When presents in the perineal region are aggressive and the suitable surgical treatment is not well defined. The authors report the case of a young patient, feminine sex, that presents a perineal nodulation for eight months. At the physical examination was noticed bulging in left perineal region, where a fibroelastic mass of approximately 10 cm of diameter was palpable. Magnetic nuclear resonance showed voluminous left-sided solid formation of regular contours in perineal region, without signals of perilesional infiltration. The chosed treatment was the excision with ample margins. The patient is currently in ambulatorial accompaniment, without signals of local recurrence.
