皮脂腺癌是由眼睑皮脂腺发展而来的恶性肿瘤。因它与其他侵蚀性较少的眼睑病变很类似,故在临床上诊断是困难的。这几乎无例外地将导致贻误诊断和恰当的治疗,甚至造成死亡的后果。当鉴定一个持续性、复发性单侧眼险疾患或非典型的常见眼睑病变时,应考虑该病的诊断。本文通过报告3例皮脂腺癌说明其发生方式是多样性的,对此种病例必须做活检。病例1:女性,65岁。1977年7月主诉左上睑有一缓慢增长的无疼性肿块已6个月之久。检查见左上睑中部近睑缘处有一2×2mm大小的囊性病变,并向上扩展达睑板。相应的结膜被伸展,但无溃疡及炎症。下睑无受累、其它眼部检 Sebaceous gland cancer is a malignant tumor developed from the eyelid sebaceous glands.
