Extra-articular diffuse tenosynovial giant cell tumour of the infratemporal fossa: report of a case and literature review.
The authors describe a 34-year-old man who presented with an unapparent swelling on the right preauricular zygomatic region, with progressive limitation of mouth opening and slight temporomandibular joint pain. Based on fine-needle aspiration cytology and radiological investigations, the patient was diagnosed preoperatively as having a possible tenosynovial giant cell tumour (TGCT). Surgical treatment was effective and no local recurrence was observed. Histological and immunohistochemical examination diagnosed an extra-articular diffuse TGCT. The clinical features, histopathological characteristics, imaging modalities, diagnostic methods and treatment of TGCT are discussed and a review of the relevant literature is presented.
