Aim: Haemangiopericytoma (HPC) represents approximately 3% of all tumours in the head and neck. This tumour is a soft tissue tumour derived from mesenchymal cells with pericytic differentiation. We present the clinicopathological findings of a case. Materials and Methods: A 69‐year‐old man was referred to our Department for a mass located on the right pre‐molar maxillary gingiva; this mass caused problems during chewing, but was otherwise asymptomatic. Results: Clinical examination revealed a nodular, pink lesion, 3.5 cm in diameter, which was lined with normal mucosa. The lesion was mobile in relation to the deep and superficial tissues. Microscopic analysis of the neoplasm showed a vascular rich pattern, constituted by vessels covered with flat endothelium and surrounded by abundant spindly cells . On the basis of these histological and immunohistochemical findings, the final diagnosis was HPC. Conclusions: HPC is an uncommon vascular tumour for which the biological behaviour is difficult to predict. In our patient, no recurrences or distant metastases were present at a 4 years follow‐up.
