Solitary fibrous tumours ( SFT s) are uncommon benign mesenchymal neoplasms that occur relatively rarely in the oral cavity. An SFT in the tongue of a 67‐year‐old woman is presented. A firm, asymptomatic, dome‐shaped mass was found on the left ventral surface of the tongue. Complete surgical resection of the mass was performed. Microscopically, the tumour was well‐circumscribed and composed of variably cellular and patternless distributions of bland spindle and ovoid cells within variably collagenous stroma, with interspersed large branching or “staghorn”‐shaped vessels. Immunohistochemically, tumour cells were positive for CD 34 and STAT 6, but negative for CD 68, S‐100 protein, epithelial membrane antigen and α‐smooth muscle actin.
