Spindle Cell Lipoma of the Flank: A Case Report

ABSTRACT

Spindle cell lipoma (SCL) is a relatively uncommon, benign tumor that usually presents in the subcutaneous fat of adult men. Histopatholgical findings show the lipomatous tissue to be replaced by a mixture of uniform spindle cells and mature fat cells closely within a mucoid matrix. We report a first case of SCL in a 24-year-old female. She had a solitary subcutaneous mass on right flank. Immunohistochemical staining shows positive for vimentin, CD34, but negative for S-100 protein. The patient was excised and showed no evidence of recurrence.
