TY - JOUR T1 - Metachronous Carcinoma at Colostomy Site Post Abdominoperineal Resection – A Rare Presentation Case Report A1 - Muhammed Huzaifa A1 - Ankita Singh A1 - Vaibhav Aggarwal A1 - Anita Dhar JF - Clinical Cancer Investigation Journal JO - Clin Cancer Investig J SN - 2278-0513 Y1 - 2023 VL - 12 IS - 2 DO - 10.51847/ZP8HS1y926 SP - 1 EP - 3 N2 - Adenocarcinoma at the colostomy site rarely occurs after abdominopelvic resection (APR), only a handful of cases are reported in the literature. In absence of biopsy such growth may masquerade as hyperplasia or granulation tissue at stomal edges, leading to diagnostic dilemmas. We report an unusual case of a gentleman in his late 50s who underwent abdominoperineal resection for rectal cancer following which he presented with stomal site growth without distant metastasis 12 years later. In view of the absence of distant metastasis, segmental colonic resection with 2 cm skin margin and revision colostomy was performed with a plan of adjuvant therapy thereafter. Though carcinoma at the colostomy site is uncommon, careful stomal observation and examination for surveillance should be done during each follow-up and we suggest early biopsy and colonoscopy in case of suspicion. Segmental colonic resection with skin margin and adjuvant therapy is the preferred option in such presentations.
