Journal Article

Introduction A colorectal inflammatory myofibroblastic tumour (IMT) is a rare but benign entity masquerading as a malignant tumour. Although the lung is considered the most common site of occurrence, IMTs may arise in diverse extrapulmonary locations. We describe a case of a colonic IMT in a patient who presented in the emergency setting. Case History A 77-year-old man was admitted at our emergency department with acute abdominal pain. Physical examination revealed vague tenderness of the lower abdomen and non-palpable masses. Preoperative evaluation revealed a mass in the right lower quadrant of the abdomen, possibly originating from the terminal ileum, 1-2cm from the caecum. Owing to the clinical impression of a potentially malignant lesion, the patient underwent subtotal colectomy and omentectomy. The pathology report suggested the morphological and immunohistochemical features were more compatible with a colonic IMT. Conclusions A colorectal IMT is a rare clinical entity that can easily mimic a highly malignant tumour and cannot be distinguished clinically or radiologically. An accurate diagnosis is based on histological examination and surgical resection is therefore usually required.
