ABSTRACT
Neurofibromas are usually manifestations of neurofibromatosis type 1 (Nf1). There are usually multiple lesions on presentation. Solitary neurofibromas of the colon are extremely rare. A 34-year-old Asian male came to our hospital for non-specific findings, except for a complaint of loose stools for 2 months. A colonoscopy was performed. A sessile polyp 0.4 cm in diameter was detected at the sigmoid colon. Microscopically, a biopsy from the polyp showed proliferation of spindle cells in the mucosa, myxoid changes and infiltration of inflammatory cells. Immunohistochemical staining was positive for S-100 protein. The above morphological and immunohistochemical characteristics were consistent with a diagnosis of a neurofibroma. Only 13 cases of isolated colonic neurofibromatosis without Nf1 have been documented in the literature. We report this case as an isolated neurofibroma of the colon is even a rarer manifestation, and only three cases have been published in the clinical literature.
