UNLABELLED
Sebaceoma is a rare benign tumor arising from the sebaceous gland of the skin. Sebaceoma often occurs on the head and neck but rarely on the ears. We present the case of a 78-year-old female patient with a two-year history of a protruding mass in her left ear. Physical examination revealed a well-circumscribed plaque in the crus of the helix of the left ear. A wide local excisional biopsy was taken, and the mass was subjected to histopathologic assessment. While the mass showed cytological findings indicating sebaceoma, it also presented malignant features architecturally and immunohistochemically. Based on these findings, the tumor was regarded as a sebaceoma of borderline malignancy.

未标注
皮脂腺瘤是一种罕见的起源于皮肤皮脂腺的良性肿瘤。皮脂腺瘤常发生于头颈部，但很少发生于耳部。我们报告一例78岁女性患者，左耳出现突出肿物两年。体格检查发现左耳耳轮脚处有一个边界清楚的斑块。进行了广泛的局部切除活检，并对肿物进行了组织病理学评估。虽然肿物的细胞学表现提示为皮脂腺瘤，但在结构和免疫组化方面也呈现出恶性特征。基于这些发现，该肿瘤被视为交界性恶性皮脂腺瘤。
