Abstract

Granular cell ameloblastoma is a variant of ameloblastoma where cells located in the central portion of the follicles have granular eosinophilic cytoplasm and the peripheral cells resemble ameloblasts. A case of granular cell ameloblastoma of the mandible having very similar histopathological features of oncocytoma (oxyphilic adenoma) is reported where tumor cells were arranged in cords, sheets and follicles and their cytoplasm was full of eosinophilic granules.

摘要

颗粒细胞成釉细胞瘤是成釉细胞瘤的一种变体，其中位于滤泡中心部分的细胞具有颗粒状嗜酸性细胞质，而周边细胞类似于成釉细胞。本文报告一例下颌骨颗粒细胞成釉细胞瘤，其具有与嗜酸性细胞瘤（嗜酸性腺瘤）非常相似的组织病理学特征，肿瘤细胞呈条索状、片状和滤泡状排列，其细胞质充满嗜酸性颗粒。
