A Rare Case of an Inflammatory Myofibroblastic Tumour of the Colon as a Probable Result of Tumour Recurrence after Hemicolectomy

Abstract

Inflammatory myofibroblastic tumour (IMT) is a very rare mesenchymal solid tumour commonly found in children and young adults, but also found to be present in older population groups. This case report presents a 33-year-old male patient who was pathologically confirmed to have an IMT of the colon after hemicolectomy and biopsy. The patient presented with abdominal pain and vomiting along with lower gastrointestinal tract bleeding. Colonoscopy of the patient revealed a fungating annular growth in the descending colon. CT also showed annular mass and inflammation of neoplastic process in the entire descending colon and mid-to-transverse colon after hemicolectomy, which may be a result of recurrence of the tumour. Surgical histopathological reports showed infiltrates of polymorphous cells consisting of lymphocytes, eosinophils, and plasma cells. The aim of this case report was to course through the history, pertinent laboratory test, and plans of management for a case of a young male with an IMT presenting with symptoms of abdominal pain and vomiting.
