Inflammatory myofibroblastic tumour (IMT) is a rare benign lesion of unknown aetiology. It mimics, clinically and radiologically, malignant tumours (especially sarcoma). It was initially described in the lung, but it was subsequently recognised that virtually any anatomic location can be involved. IMTs of the gastro-intestinal tract are rare and there have been only nine confirmed cases involving the appendix to date. We presented a 20-year-old male patient with a diagnosis of IMT that caused acute appendicitis. An appendectomy is the most efficient treatment in cases where the lesion is limited to the appendix. Being aware of such an entity and being careful in the differential diagnosis of the appendiceal masses, especially the large masses, may prevent overtreatment.

Inflammatory myofibroblastic tumor (IMT) is a rare soft-tissue neoplasm of unknown etiology. It mimics, clinically and radiologically, malignant tumors. Histologically, this tumor is composed of differentiated myofibroblastic spindle cells accompanied by an inflammatory infiltrate, with numerous plasma cells and/or lymphocytes. Initially described in the lung, numerous extrapulmonary sites of this tumor have been found but appendiceal IMT is rare, especially in adult women. In this study, we aimed to examine the literature as well as to describe a case of a 42-year-old woman that we operated on that presented as an appendiceal mass that obstructed the lumen of the appendix and caused acute appendicitis. Upon histopathological examination, the lesion was identified as an IMT. Awareness of this type of tumor in the differential diagnosis of appendiceal masses, avoids overtreatment, and highlights the need of long-term follow-up regarding the tendency for local recurrence and small risk of distant metastasis.
