Haemangiopericytoma/Solitary Fibrous Tumour of Mandible: An Uncommonness in the Oral Cavity.

Among the bewildering variety of neoplasms occurring in the head and neck region, few are unique to the oral cavity which are quite challenging to diagnose. Due to the rarity of these tumours, it is the practicing oral pathologists' accountability to confirm some of these neoplasms with or without special investigative modalities to rule out the differential diagnosis histopathologically. One in the group of such tumour prevails haemangiopericytoma aka. solitary fibrous tumour (HPC/SFT). The management of these tumours is purely histopathologically driven, since the surgical procedure is dependent on the histological diagnosis. This neoplasm is histologically very difficult to confirm as benign or malignant without the use of immunohistochemical markers. We report such a rare case of a 54-year-old female patient, histopathologically confirmed diagnosis of HPC/SFT with CD34 positivity for documentation in the literature. © The Association of Oral and Maxillofacial Surgeons of India 2019.
