Large mass arising from the tongue as an initially and sole manifestation of Kaposi sarcoma.

We report a 30- year-old Iranian woman presenting with a red to yellowish, well demarcated, painless exophytic and lobulated mass originating from the right hand side of the tongue. An excisional biopsy was obtained and it was diagnosed histopathologically as Kaposi's sarcoma by detecting atypical spindle cells with rare mitoses delineating blood-filled vascular slits.
