“…8 Sarcomas that occur in the perineum can be classified as superficial and deep depending on their position in relation to the muscular fascia. 9 Tumors higher can invade the rectum and the sphincter. 10 They are very aggressive and recurrence and metastases are common, in these cases chemotherapy and radiotherapy may be used but with poor results.…”

Primary tumors of the ischiorectal fossa are rare, they can be congenital, acquired or neoplastic. Accurate diagnosis often cannot be done preoperatively and imaging studies such as computed tomography and especially magnetic resonance imaging can define the size and anatomical relationships of the lesions. Surgical treatment is challenging because of difficult access of the region which is preferably performed by posterior approach. We describe the etiology, diagnosis and operative technique of tumors of the ischiorectal fossa.

High Grade Leiomyosarcoma Mimicking a Recurrent Angiomyxoma in the Perineum

et al. 2015

Perineal leiomyosarcoma is an extremely rare and aggressive cancer with a high metastatic potential and no defined standard treatment. There are only a few (six) reported cases in the literature. We report the case of a 67-year-old woman with a perineal leiomyosarcoma arising at the same site of a previously resected superficial angiomyxoma. Initially, she was treated for a presumptive recurrence of angiomyxoma. As she did not respond to medical therapy, she underwent repeat surgical excision. Pathology revealed a high grade leiomyosarcoma, histologically strikingly distinct from the initial diagnosis. She received adjuvant local radiation therapy, and remains without evidence of recurrent disease 36 months after completion of all therapy. This is the first reported case of a high grade perineal leiomyosarcoma originating at the same site as a resected benign superficial angiomyxoma. Our case emphasizes the necessity of a prompt histological diagnosis in cases of presumed recurrent perineal angiomyxoma.
