Choristomas are proliferation of normal cells or tissue in an abnormal location. Choristomas of oral soft tissue are rare lesions. Different tissues can occur in the oral cavity as choristomas. It can be cartilage, bone, salivary gland, glial and thyroid tissue. Choristomas with the proliferation of chondroid tissue are termed as cartilaginous choristomas. In oral cavity, they are most frequently seen in tongue followed by buccal mucosa and soft palate. We report a case of 40-year-old female presenting with hard lobulated swelling on the left lateral border of the tongue. Fine-needle aspiration cytology was performed which showed only myxoid stroma. Histopathological examination of excised specimen of the same showed lobules of mature hyaline cartilage. Thus, a diagnosis of cartilaginous choristoma was made.
迷离瘤是正常细胞或组织在异常部位的增殖。口腔软组织迷离瘤是罕见病变。不同组织可作为迷离瘤出现在口腔内。它可以是软骨、骨、唾液腺、神经胶质和甲状腺组织。伴有软骨样组织增殖的迷离瘤被称为软骨迷离瘤。在口腔中，它们最常出现在舌部，其次是颊黏膜和软腭。我们报告一例40岁女性，其舌左侧缘出现坚硬的分叶状肿胀。进行了细针穿刺细胞学检查，结果仅显示黏液样基质。对切除标本进行组织病理学检查显示为成熟透明软骨小叶。因此，诊断为软骨迷离瘤。
