A Rare Case of Primary Squamous Cell Carcinoma At Ileostomy Site: Case Report

Abstract

Primary squamous cell carcinoma at ileostomy site is extremely rare and there are only eight reported cases prior to our report. The present case report describes a patient of ileostomy formation 12 years prior to evaluation after total colectomy who now presented with mass at stomal and parastomal site and underwent biopsy and Positron emission tomography (PET) scan. Tumor was suspected and hence wide local excision with en bloc resection of the ileostomy and ileo-rectal anastomosis was done and histopathology showed differentiated Squamous cell carcinoma (SCC), Grade 1. This case underlines the need of regular follow-up of patients with stomas to allow the timely detection of stomal problems and the early diagnosis and management of the rare complication of parastomal squamous-cell carcinoma. Also, persistent peristomal ulcerations and proliferative lesions must undergo biopsies to rule out malignancy. Wide local excision of the carcinoma with en bloc resection of ileostomy and formation of new ileostomy at a different site is usually done to manage such cases.
