History: This small bowel lesion was strongly reactive with S100 protein but not keratins. What is your diagnosis?
Comment: This nice small bowel nerve sheath tumor conforms well to "reticular schwannoma" of the GIT; we had earlier termed them as benign epithelioid nerve sheath tumor of the mucosa - the initial series of lesions that we saw were all mucosal based. Regardless of the involved layer, these lesions are benign but can mimic carcinoma on frozen sections.
