Tumor of the follicular infundibulum or infundibuloma is a relatively rare benign adnexal tumor usually solitary and located in the head, neck, and trunk. Here we present a 70-year-old woman with a tender vulvar lesion. Histopathologic exam shows a well-circumscribed lesion with a subepidermal horizontally oriented, plate-like proliferation of pale appearing squamous epithelial cells with numerous points of connections with the overlying epidermis and peripheral palisading. Overall these histopathologic features are consistent with the diagnosis of tumor of follicular infundibulum involving genital skin.
毛囊漏斗部肿瘤或漏斗部瘤是一种相对罕见的良性附属器肿瘤，通常为单发，位于头、颈和躯干。本文报告一名70岁女性，有一处外阴部压痛性病变。组织病理学检查显示病变边界清晰，在表皮下可见水平方向的板层状淡染鳞状上皮细胞增生，与上方表皮有多处连接，周边呈栅栏状排列。总体而言，这些组织病理学特征符合累及生殖器皮肤的毛囊漏斗部肿瘤的诊断。
