We report a case of primary angiosarcoma of gingiva along with a review of 31 cases of primary gingival angiosarcoma reported in literature till 2018. A 30-year-old lady presented with recurrent gingival swelling over central mandible. She had no palpable cervical lymphadenopathy. She underwent central marginal mandibulectomy.
