An extremely rare case of spindle cell lipoma of the cheek is presented. The patient was a 45-year-old woman. Physical examination revealed a mobile, well-demarcated, 10mm-diameter mass in the right cheek. Examination of a biopsy specimen showed proliferation of mature adipocytes, leading to the diagnosis of a lipoma. The tumor started to enlarge 2 and a half years after biopsy. Histologic examination of the removed specimen showed that the tumor was composed of mature adipocytes and spindle cells. A diagnosis of spindle cell lipoma was made.
