Vulvar Skin Metastasis of Lung Squamous Cell Carcinoma

ABSTRACT

In this study, we examined a case where lung cancer metastasized to the vulvar area. A 79-year-old woman that was a heavy smoker was referred to our department with a short (two-week) history of dyspnea, and with a painful nodule on her right labium majora, which she had noticed almost three years earlier. Histopathologically, the specimen appeared as a poorly differentiated squamous cell carcinoma. The chest X-ray, chest computerized tomography scan, and percutaneous transthoracic needle biopsy via bronchoscopy revealed squamous cell carcinoma in the right upper lobe of the lung. Based on these clinical and histopathological findings, we concluded that her condition was skin metastasis at the right labium majora from the lung cancer, which occurs very rarely.
