Metastatic basal cell carcinoma presenting with unilateral upper extremity edema and lymphatic spread.

Basal cell carcinoma (BCC), the most common human malignancy, metastasizes in 0.0028% to 0.5% of cases, usually to the lymph nodes, lungs, bones, and skin. After metastatic spread of BCC, survival averages 1 to 2 years. Chemotherapy, radiotherapy, and surgery are treatment options. We describe metastatic basal cell carcinoma to the skin presenting with unilateral upper extremity edema.
