Asymptomatic lung carcinoma presenting with a large vulvar lesion

Objective. Metastases to the vulva are infrequent, accounting for less than 10% of vulvar tumors. Vulvar metastases from lung carcinoma have been reported in two other cases. Methods. A case of lung carcinoma metastatic to the vulva is reported. Results. A 71-year-old woman was referred to the University of Iowa Hospitals and Clinics with a lung nodule on chest x-ray and a 12-cm, necrotic, left vulvar mass. A lung biopsy showed poorly differentiated carcinoma, and a palliative resection of the vulvar mass showed metastatic lung carcinoma. The patient died from sepsis on postoperative day 10. Conclusions. Lung carcinoma metastatic to the vulva is rare and portends a poor prognosis.
