Axillary and subcutaneous breast metastases from rhinopharyngeal carcinoma: a case report and literature review.

The incidence of rhinopharyngeal carcinoma is fewer than one person per 100,000 population but it is one of the most common types of cancer in Southern China. The mechanisms often implicated suggest an important role of genetic, ethnic and environmental factors. Lung metastases are the most frequent, accounting for 66% of distant metastases. Other metastatic sites include bone (22%) and liver (10%). We report a case with breast skin and axillary nodes involvement.
