Upper lip metastasis of sarcomatoid carcinoma of the lung - An unusual site of disease: A case report

Background: Lip metastases are rare clinical events that are frequently mistaken for other diagnoses. For sarcomatoid lung carcinoma, a rare histologic variant of non-small cell lung cancer, the incidence and pattern of cutaneous spread is poorly understood. Case presentation: We present a case of a 79-year-old African American man with a rapidly progressive upper lip cutaneous lesion that provided the first evidence of distant metastatic spread of sarcomatoid lung carcinoma. Conclusions: This is the first reported case of lip metastasis in sarcomatoid lung carcinoma. It highlights the importance of maintaining a high level of suspicion for metastatic disease in the presence of new cutaneous findings as they may be the first evidence of advanced disease.
