We present a non-healing lesion on the gingivae attached to the mandible that mimicked periodontal disease, and was refractory to local debridement and oral hygiene measures. Biopsy examination showed a metastatic epithelioid haemangioendothelioma. This rare vascular tumour is considered to be malignant and management is controversial, owing to the paucity of published data. Treatment was provided in a multi-disciplinary setting as a result of established pulmonary and musculoskeletal metastases. The patient opted for conservative management and close surveillance of the lesion, which continues to remain stable at the time of writing, nearly two years after the initial assessment.
