Resumo: A 27-year-old men sought health care complaining of discomfort and drainage of purulent secretion in the retromolar region of mandible. Clinical examination revealed a slight volume increase of left buccal bone plate, effacement of vestibule fundus, drainage of white/yellow content from gingival sulcus of thooth 37, and moderate painful symptoms on palpation. Radiographic examination revealed a well-delimited, multiloculated radiolucent image, extending from periapical region of tooth 37 to the middle portion of mandible ramus. Diagnostic hypothesis were keratocyst and ameloblastoma. Aspiration puncture revealed reddish content. An incisional biopsy was performed and the lesion was decompressed with a drain. Histopathological evaluation reported lesion compatible with fusocellular injury of uncertain nature. Immunohistochemical evaluation showed positive CD34 (QBEnd10), Vimetine (VIM3B4) and low Ki67 antigen (KiS5) expression. Three months follow-up showed bone neoformation in the entire extension of the lesion. The final diagnosis was a secondarily infected cystic lesion.
