Abstract
Urachal tumors are rare and comprise of both benign and malignant neoplasms. Epithelial origin tumors are more common than mesenchymal origin tumors. We report a case Urachal inflammatory myofibroblastic tumor (IMFT) in a 12 year old boy who presented with symptoms of lower abdominal pain and burning micturition. Upon evaluation was found to have a soft tissue mass anterior to urinary bladder wall. A laparoscopic excision of tumor was done. Histopathological and immunohistochemical examination confirmed the diagnosis of IMFT. Next generation sequencing identified FN1-ALK gene fusion.
