Schwannomas are rare tumors originating from the Schwann cells, that form the neural sheath. These tumors occur most frequently in the head, neck, arms and limbs. Primary schwannomas of the colon and rectum are extremely rare. They are usually benign. Pre-operative biopsy examinations may be difficult and immunohistochemistry is necessary for the correct diagnosis. In contrast to gastrointestinal stromal tumors, schwannomas are negative for CD117 and positive for S100 protein and vimentin. In extremely rare cases, they can present with malignant degeneration if not surgically removed. Therefore, the gold standard treatment for schwannomas is surgical resection.

Rare tumors of the colon and rectum account for less than 5% of all colorectal tumors. The most common of these rare tumors include anorectal melanoma, rectal neuroendocrine tumors, rectal gastrointestinal stromal tumors (GISTs), and retrorectal tumors. Their prognosis is varied and depends on underling pathology. Surgery plays an important role in many of these tumors. Molecularly targeted therapy and immunotherapy have expanding roles in GIST and anal melanoma, respectively. Adjuvant chemotherapy or radiation therapy may be employed in specific circumstances of unresectable or metastatic disease or for symptom control.  This review contains 4 figures, 6 tables and 60 references.  Key words: anal canal, antineoplastic agents, anus neoplasms, chordoma, gastrointestinal stromal tumors, melanoma, neuroendocrine tumors, operative, radiotherapy, rectal neoplasms, surgical procedures
