Spindle cell haemangioma (SCH) is a benign vascular lesion which usually occurs on distal extremities. It was previously regarded as haemangioendothelioma and was initially perceived to be low grade angiosarcoma.They are characterized by cavernous blood vessels and spindle cell proliferation. It is now considered as a reactive lesion and conservative surgical excision is preferred treatment. Intraoral occurrence is rare; hence we present a case of SCH in a 33-year-old male that presented as a swelling below the tongue. Histopathology showed well circumscribed proliferating spindle cells attached to vessel walls, dilated vascular spaces. The lesion was positive for CD31 and CD34 markers suggesting it to be of endothelial cell origin.
