| Abstract |
|
Schwannomas are mainly benign tumors arising from the sheath of the peripheral nerves. Gastrointestinal schwannomas account for 2-6% of all gastrointestinal tumors; they originate most commonly in the stomach, and are extremely rare in the appendix. Their clinical features are non-specific, thus, they are usually found accidentally through radiologic examinations and confirmed by immunohistochemical stainings. A 39-year-old male was admitted with complaints of right lower quadrant pain. There was a well-enhancing tumor in the appendix on a computed tomography scan. It was laparoscopically resected and diagnosed as appendiceal schwannoma with histopathologic and immunohistochemical findings. There has been no evidence of specific complication or recurrence until now for the past 22 months. (Intest Res 2013;11:223-226) |
