Tactile corpuscle-like bodies in colonic mucosa.
During the routine examination of a segment of colon resected for adenocarcinoma, a diffuse proliferation of mucosal tactile corpuscle-like bodies was identified. The bodies showed a lamellar structure by light microscopy and were S-100 positive. Electron microscopy demonstrated parallel slender processes with prominent surface caveolae, arising from peripheral cell bodies. Similar structures sometimes occur in neurofibromas but they have not previously been reported in the gastrointestinal tract.
