Summary:Leiomyosarcoma is a malignant neoplasm of smooth muscle origin that is rare in external soft tissues of the head and neck region. We observed a subcutaneous leiomyosarcoma in the cheek of a 61-year-old man. Diagnosis was difficult since the tumor grew slowly and clinically formed a solitary painless mass. Histopathologically, the tumor consisted of spindle-shaped atypical myomatous cells, had poor proliferation, and was composed of interlacing fascicles that merged into collagenous stroma. Immunohistochemically, the spindle-shaped tumor cells were stained by vimentin and α-smooth muscle actin.
