A yellow cyst of the caruncle in a 68-year-old man displayed the characteristic sebaceous glands and sebocytes of steatocystoma within the cyst wall, with a unique configuration of multiple branching compartments. The cyst lining was of trichilemmal character, lacking a keratohyalin granular layer, and replicated the immunohistochemical characteristics of a previously reported caruncular steatocystoma with the exception of a positive trichilemmal marker, calretinin, in the present case. Four previous cases of caruncular steatocystoma have been described, only one of which incorporated immunohistochemical analysis. Steatocystoma develops from a sebaceous gland duct, which displayed in this case multiple chambers subdividing what is usually a single round lumen.
一名 68 岁男性的结膜黄色囊肿显示出特征性的皮脂腺和囊壁内的皮脂腺上皮细胞，具有独特的多分支隔室结构。囊肿衬里具有毛母质细胞特征，缺乏角蛋白透明颗粒层，并复制了先前报道的结膜皮脂腺上皮囊肿的免疫组织化学特征，除了在本病例中出现阳性的毛母质标志物钙视网膜蛋白。已经描述了四个先前的结膜皮脂腺上皮囊肿病例，其中只有一个进行了免疫组织化学分析。皮脂腺上皮囊肿来源于皮脂腺导管，在该病例中，多个隔室将通常为单个圆形腔室分隔开来。
