An extremely rare hamartomatous lesion of the juxtaoral organ of Chievitz (JOOC) in a 63 year old man is reported. The tumour appeared as a large mass in the infratemporal fossa with associated mandibular bone resorption; histologically, it was well encapsulated and composed of numerous tangled masses of benign squamous epithelial nests and mature fibrofatty tissue. There were no histological features suggestive of neoplastic transformation. A literature survey confirmed that this is the first adult case of JOOC presenting clinically as an extraoral tumour.
报告了一名63岁男性中极为罕见的奇维茨口周器官(JOOC)错构瘤样病变。肿瘤表现为颞下窝的一个大肿块,并伴有下颌骨吸收;组织学上,它被完整包裹,由大量良性鳞状上皮巢和成熟纤维脂肪组织的缠结团块组成。没有提示肿瘤转化的组织学特征。文献检索证实,这是首例临床上表现为口外肿瘤的成人JOOC病例。
