Choristomas are rare entities which are aggregates of microscopically normal cells or tissues in aberrant locations. They are a "heterotopic" rest of cells, as they appear as a tumor-like mass. Herein we report a case of cartilaginous choristoma in a 54-year-old male who presented with a swelling on right lower gingiva. The histopathological examination revealed features of a well circumscribed mass of mature cartilage in a dense fibrous connective tissue stroma.
迷离瘤是罕见的实体，由位于异常部位的显微镜下正常的细胞或组织聚集而成。它们是细胞的“异位”残余，表现为肿瘤样肿块。在此，我们报告一例54岁男性的软骨迷离瘤，该患者右下牙龈出现肿胀。组织病理学检查显示，在致密的纤维结缔组织基质中有一个边界清晰的成熟软骨肿块。
