Inflammatory pseudotumour of the colon

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.

Recurrent retroperitoneal inflammatory myofibroblastic tumor: A case report

Inflammatory myofibroblastic tumor (IMT), which was previously known as inflammatory pseudotumor, is characterized by myofibroblastic spindle cells accompanied by inflammatory infiltrates. IMT is a rare lesion of unclear etiology, which induces non-specific clinical symptoms. The present case report describes a 74-year-old female patient with recurrent IMT, which was successfully re-resected 30 months subsequent to initial surgical removal. The patient presented with left hydroureteronephrosis and a 10-cm paravertebral mass which, upon surgery, was found to involve the descending colon. Successful, complete en bloc re-resection was achieved, and at 24 months follow-up, the patient remained clinically free of disease. Complete surgical extirpation, where feasible, is the recommended treatment for primary and recurrent IMT lesions.

Inflammatory myofibroblastic tumor of the breast

Inflammatory myofibroblastic tumors (IMTs) of the breast represent extremely rare lesions. Due to the scarcity of reports, their natural history, recurrence, and metastatic potential remain poorly defined. We report on a case of a primary breast IMT in a postmenopausal female patient treated successfully with breast conserving surgery and review the literature pertaining to this rare entity.
