摘要

背景:在所有癌症患者中，皮肤转移发生率为0.7% - 9%，通常被认为是大多数内脏癌发展的晚期事件。鼻尖结节性转移病灶的发展被称为小丑鼻征。主要观察:我们报告了一位64岁的男性，他的鼻尖上出现了一个结节性病变，这是鳞状肺癌的第一个表现。结论:皮肤转移活检可能有助于组织病理学证实疑似原发肿瘤，避免侵入性诊断。

"Clown nose" as first manifestation of squamous cell carcinoma of the lung.

Background: Skin metastases occur in 0.7% to 9% of all patients with cancer and are usually considered a late event in the evolution of most visceral carcinomas. The development of a nodular metastatic lesion on the nasal tip is known as clown nose sign.

Main observation: We report a 64-year-old man that developed a nodular lesion on his nasal tip as first manifestation of squamous lung carcinoma.

Conclusion: The biopsy of the cutaneous metastasis may be helpful to histopathologically confirm the suspected primary tumour avoiding invasive diagnostic procedures.
