Abstract

We present a case report of a patient who developed a sinonasal myopericytoma treated by surgical excision through a lateral rhinotomy. Some aggressive features on pre-operative computed tomography scanning and the complexity of recent changes in the histological nomenclature for these tumours led to consideration of adjuvant therapy. The close histological relationship between myopericytoma, myofibromatosis, solitary myofibroma and infantile haemangiopericytoma is discussed. This group of lesions constitute a single morphological spectrum with differentiation towards perivascular myoid cells (pericytes). Currently myopericytoma is the most appropriate and accepted term embracing all these entities. A review of the literature has been reassuring in identifying these tumours as benign but with a reasonably high rate of local recurrence (17 per cent). The treatment of choice is surgical excision with further excisions for local recurrence.
