Abstract

UNLABELLED

Ameloblastoma is an uncommon benign epithelial neoplasm of odontogenic origin that accounts for about 18% of the odontogenic tumour. It is a slow-growing, locally invasive but rarely metastatic tumour. Extraosseously occurring peripheral ameloblastoma is a rare variant that comprises about 2-10% of all ameloblastoma. We report a case of peripheral ameloblastoma in a 43-years old male patient affecting the mandibular canine-premolar region with a histopathological diagnosis of acanthomatous ameloblastoma. This case report emphasises the clinical, radiographic, and histological features of a rare variant that distinguishes it from the other similar appearing lesion on gingiva along with its various treatment modalities.

摘要

背景

成釉细胞瘤是一种少见的良性牙源性上皮性肿瘤，约占牙源性肿瘤的 18%。它是一种生长缓慢、局部侵袭性但很少转移的肿瘤。发生于骨外的外周性成釉细胞瘤是一种罕见的变异型，约占所有成釉细胞瘤的 2-10%。我们报告了一例发生于 43 岁男性患者的下颌尖牙-前磨牙区的外周性成釉细胞瘤，其组织病理学诊断为棘皮瘤型成釉细胞瘤。本病例报告强调了这种罕见变异型的临床、影像学和组织学特征，使其与牙龈上其他类似的病变以及其各种治疗方式相区别。
