Abstract: PURPOSE: To analyze the clinical features, histopathologic features, differential diagnosis and treatment of extra-orbital giant cell angiofibroma(EO-GCA) in oromaxillofacial head and neck region. METHODS: Data on 12 cases of EO-GCA reported in PubMed database and 2 cases in our hospital were collected and analyzed. RESULTS: Fourteen patients (nine females, five males) were included, their ages ranged from 24 to 84 years with an average age of 43.5 years. Most cases presented a slow-growing and painless mass. The size of the tumor was related to the anatomic location. Microscopic examination revealed a patternless ovoid or short spindle tumor cell, richly vascularized, and floret-like multinucleated giant cells. Immunohistochemical staining revealed strong positivity for the mesenchymal markers, such as CD34 and vimentin. Clinical misdiagnosis was common and final diagnosis relies on pathology. Complete surgical resection of the tumor can lead to a better prognosis and little local recurrence. CONCLUSIONS: EO-GCA in oromaxillofacial head and neck region is a rare benign soft tissue tumor easily misdiagnosed. Accurate diagnosis depends on histopathological examination. Complete surgical resection of the tumor has a better prognosis.
