Leiomyosarcoma of the maxilla: a rare challenging case

Leiomyosarcoma (LMS) is a rare malignant lesion of head and neck region. It usually arises from smooth muscle cells of blood vessel wall in this area. Clinically, the tumour often presents as a slow-growing, painless destructive mass with a relatively firm consistency. It usually involves adults, and is rarely reported in children. Here, we report a case of LMS of maxilla in a 73-year-old male with a destructive behaviour and also discuss the diagnostic procedure proposed to make a definitive diagnosis in such unusual cases.
