Nevus sebaceus of Jadassohn, a congenital cutaneous hamartoma, has the potential to develop into various epidermal adnexal-origin neoplasms. While the most common neoplasms are trichoblastoma or syringocystadenoma, proliferating trichilemmal cysts are exceptionally rare. We report a case of a 63-year-old Cuban male with a giant proliferating trichilemmal cyst arising from a nevus sebaceus on the right shoulder which had been growing for 30 years. Proliferating trichilemmal cysts arising from nevus sebaceus cases are difficult to diagnose clinically and histologically as they are very rare and have not been defined by exact diagnostic criteria. Our case creates awareness of this particular tumor in nevus sebaceus and shares clinical and histological diagnostic information that can be used to make a proper diagnosis.
Jadassohn皮脂腺痣是一种先天性皮肤错构瘤，有发展为各种表皮附属器起源肿瘤的可能。虽然最常见的肿瘤是毛母细胞瘤或汗腺囊腺瘤，但增生性外毛根鞘囊肿极为罕见。我们报告一例63岁古巴男性病例，其右肩部皮脂腺痣上长出一个巨大的增生性外毛根鞘囊肿，该囊肿已生长30年。皮脂腺痣病例中出现的增生性外毛根鞘囊肿在临床和组织学上都很难诊断，因为它们非常罕见，且尚无确切的诊断标准。我们的病例提高了对皮脂腺痣中这种特殊肿瘤的认识，并分享了可用于做出正确诊断的临床和组织学诊断信息。
