Gastrointestinal autonomic neural tumour of colon: a case report of rare unusual tumour of colon

Abstract

Gastrointestinal autonomic nerve tumours (GANTs) are uncommon stromal tumors of the intestinal tract. They can involve any part of the gastrointestinal system, but are very rarely seen in the Colon. We report a unique case of Gastrointestinal Autonomic Neural Tumour (GANTs) of colon extending from ascending colon to 2/3rd of the transverse colon. A 50-year-old male patient was admitted with complaint of pain in right side of abdomen. USG revealed f/s/o lymphoma/Carcinoma Colon. CECT Abdomen revealed? Lymphoma? Carcinoma extending from ascending colon to 2/3rd of the transverse colon with Lymphadenopathy. Exploratory Laparotomy was performed followed by Right Hemicolectomy. Histopathology and Immunohistochemistry confirmed the colonic lesion to be a Gastrointestinal Autonomic Neural Tumour. Literature review of the few reported cases has suggested radical surgical excision to be the best approach. Prognosis tends to be favourable after resection.
