Solitary fibrous tumour of the rectosigmoid wall: report of a case and review of the literature.

Dear Editor, Solitary fi brous tumours (SFTs) are rare, usually benign, mesenchymal tumours most commonly found in the pleura, where they were fi rst described in 1931.1 Subsequently, SFTs have been described in many other sites. To the best of our knowledge, SFTs arising from the colonic wall have not previously been reported. We report a case of an SFT arising within the wall of the rectosigmoid colon in a 53-year-old woman and discuss its differential diagnosis and clinical implications.
