Squamous cell carcinoma at an ileostomy site-Fifty-four years following colectomy for ulcerative colitis: A case report and literature review.

Introduction: Carcinoma arising at an ileostomy site is an extremely rare occurrence. The rate of malignancy arising at an ileostomy site is reported as being 2-4 of every 1000 cases. The development of squamous cell carcinoma at the mucocutaneous junction of an ileostomy is extremely rare.

Presentation Of Case: We present a case of a 76-year-old male who developed squamous cell carcinoma at an ileostomy site fifty-four years after total colectomy as management for ulcerative colitis.

Discussion: Our literature review has identified only four similar cases previously published in English literature. All cases of squamous cell carcinoma developing in ileostomy have occurred after a minimum of twenty-six years following ileostomy. This suggests that the etiology may be due to chronic factors.

Conclusion: Patients with chronic stomal inflammation, bleeding or persistent induration and/or mass formation should be followed up closely and investigated for recurrence or development of a new malignancy. There should be a low threshold to obtain an early definitive tissue diagnosis by taking biopsies to prevent local or systemic invasion.
