头皮转移作为肺鳞癌的首发表现:1例极其罕见的病例报告及文献回顾

Inaugural Scalp Metastasis of Pulmonary Squamous Cell Carcinoma:A Rare Case Report and Literature Review

原发性肺鳞癌远处转移中皮肤转移是一件罕有发生的事,而头皮转移作为患者首发的临床表现更加少见。头部皮肤转移灶很容易误诊为其他头部疾病,但它的出现提示着肺癌恶化与预后不良。这篇病例报告记录了1例以头部皮肤毛囊炎为首发表现就诊于皮肤科,通过影像学诊断为肺恶性肿瘤后转科至胸外科,头部病灶切除病理提示为肺癌的远处转移灶的女性患者,并对报道过类似病例的文章进行回顾总结。本文旨在增进对肺癌皮肤转移的了解和认识,提高对该类疾病的重视,加强早期识别、精准诊断,防止临床上对该疾病漏诊与误诊,最终达成推进后续的治疗、改善患者预后的目的。

Distant cutaneous metastasis of primary lung squamous cell carcinoma is an exceedingly rare event,with scalp metastasis as the initial clinical presentation even rarer.Scalp skin metastases are prone to be misdiagnosed as other scalp disorders,yet their appearance signifies the deterioration and poor prognosis of lung cancer.This case report documents a female patient presenting initially with scalp folliculitis in dermatology,who was subsequently diagnosed with malignant lung tumor through radiological imaging and referred to Department of Thoracic Surgery.Pathological examination of the excised lesion from the scalp revealed distant metastasis of lung cancer.A review of similar cases reported in literature was conducted.This article aims to enhance understanding and awareness of skin metastasis in lung cancer,to emphasize the importance of this condition,and to improve early recognition and precise diagnosis.It is crucial to prevent clinical misdiagnosis and ensure ap�propriate treatment,finally leading to improve the prognosis of the patients.
