AI Article Synopsis
- Schwannomas are uncommon tumors that arise from Schwann cells in the neural sheath and can be found in the gastrointestinal tract, categorized as gastrointestinal stromal tumors (GIST) alongside other tumors like leiomyoma.
- This type of tumor makes up about 2-6% of GIST, with the stomach and small intestine being the most common sites, while colon and rectal schwannomas are particularly rare.
- A case of a sigmoid schwannoma that was successfully treated is discussed in the study, along with a review of existing literature on the topic.
Article Abstract
Schwannomas are rare tumors derived from the cells of Schwann that form the neural sheath. When located in the gastrointestinal tract, they constitute together with leiomyoma, leiomyoblastoma, and leiomyosarcoma, the gastrointestinal stromal tumors (GIST). Peripheral nerve sheath tumors represent 2-6% GIST with most common location, the stomach and the small intestine. Schwannomas of the colon and rectum are extremely rare and radical excision with wide margins is mandatory, due to their tendency to recur locally and become malignant, if left untreated. In the present study, we report a rare case of a sigmoid schwannoma, which was successfully treated in our department and reviewed the literature.
