Transvaginal resection of gastrointestinal stromal tumor in the rectum.

A gastrointestinal stromal tumour (GIST) can occur anywhere in the gastrointestinal tract, though rectal GIST is rare. The primary treatment of GIST is surgical resection. Neoadjuvant imatinib treatment may cause tumor reduction and allow local resection. This is a case report of a 70-year-old woman with a high level of comorbidity who was diagnosed with a low rectal GIST. She was successfully treated with imatinib followed by complete GIST resection using a transvaginal technique.
