Rectal schwannoma.
Solitary schwannomas constitute only 2%-6% of stromal tumors of the gastrointestinal tract; the stomach is the preferred site of involvement. We report a 35-year-old woman who presented with difficulty in defecation. A mass on the posterior wall of the rectum was excised. Histologically, the lesion was a schwannoma, with S-100 proteins positivity and glial fibrillary acidic protein immunoreactivity. The patient is asymptomatic two years later.
