Abstract:
Rhabdomyoma of the pyriform sinus: case report and review of the literature. Objective: Adult rhabdomyoma is a rare benign tumour that arises from skeletal muscle. It is mostly found in the head and neck region, and it should be included in the differential diagnosis of benign lesions. Methods: A 62-year-old man presented with dysphagia, and flexible endoscopy revealed a submucosal mass obliterating the right pyriform sinus. Computed tomography imaging revealed that the mass was hyperattenuated and extended from the right pyriform sinus to the true vocal cord. The mass was excised transorally under general anesthesia with a carbon dioxide laser. Microscopically, the tumour demonstrated features of adult-type rhabdomyoma. Results: One year after surgery, the patient had no signs of recurrence. Conclusions: Rhabdomyoma is a rare neoplasm of the pyriform sinus. This entity should be considered in the differential diagnosis of tumours in this region.
