Radiation‑induced leiomyosarcoma of oral cavity: Two cases with a review of literature.

Radiation‑induced sarcoma is a rare entity, with leiomyosarcoma (LMS) in the oral cavity post radiation being extremely rare. We report two such cases who presented with swelling in the oral cavity with a history of moderately differentiated squamous cell carcinoma. Both cases prior to the diagnosis of LMS had been managed with surgery and radiation therapy and later developed swelling in the oral cavity. The management of LMS is uncertain; hence, this article aims to spread awareness about this rare diagnosis and to know the importance of differentiation from other more common lesions including recurrence.
