Solitary mass of the male pelvis

Abstract

Solitary fibrous tumor (STF) initially described as a tumor of the pleura has now been recognized at multiple anatomical sites. Pelvic STFs consist about 6% of all STFs. We present the case of a man with a long standing pelvic STF. He had symptoms of increased frequency of loose stools with passage of mucus since 2 years. A laparotomy and excision of the mass was done, but the patient developed complications and was re-explored on postoperative day 4 which showed a small rent in the anterior rectal wall mucosa. A colostomy was done after which the patient had a steady recovery. These lesions can be tricky to deal with due to their vascular nature and size. With no defined management protocol, the treatment must be tailor made and be more cautious especially when the pathology is long standing, causing pressure symptoms.
