Ameloblastoma is a rare benign odontogenic epithelial tumor characterized by abnormal cell growth, which easily infiltrates and destroys surrounding bony tissues. Clinically, it is mostly seen in the ascending ramus area, in men in their fourth and fifth decades more frequently than in women. One of the 3 clinical variants of ameloblastoma is desmoplastic type, with involvement of the maxillary arch more often than the mandible. Its histopathologic variant characterized by extensive squamous metaplasia, islands of tumor cells, and sometimes keratin formation is known as desmoplastic acanthomatous ameloblastoma.The aim of this report was to present an unusual case of symphysis located desmoplastic acanthomatous ameloblastoma in a 56-year-old female patient, who was experiencing laryngeal carcinoma 2 years ago.
成釉细胞瘤是一种罕见的良性牙源性上皮肿瘤，其特征为细胞异常生长，容易浸润并破坏周围骨组织。临床上，它多见于升支区域，40至50岁男性比女性更常见。成釉细胞瘤的3种临床变体之一是促结缔组织增生型，上颌骨受累比下颌骨更常见。其组织病理学变体的特征是广泛的鳞状化生、肿瘤细胞岛，有时还有角蛋白形成，被称为促结缔组织增生性棘皮瘤型成釉细胞瘤。本报告的目的是介绍一例不寻常的病例，一名56岁女性患者的下颌骨联合处发生促结缔组织增生性棘皮瘤型成釉细胞瘤，该患者两年前曾患喉癌。
