Solitary Fibrous Tumors of the Mesocolon: A Report of Two Cases and Review of Literature.

Solitary fibrous tumors (SFTs) are an uncommon group of neoplasms. The visceral pleura is the most common site of origin of these tumors. The colonic mesentery is an unusual site of origin of SFTs. A pre-operative diagnosis of SFT is challenging as there are no pathognomonic clinical or radiological signs. Most patients reported thus far were diagnosed post-operatively with the aid of immunohistochemical markers. Complete surgical excision is the treatment of choice for SFTs. Recurrences are uncommon. However, they can occasionally show aggressive behavior. In this report, we describe two cases of rare colonic mesentery SFTs.
