Ewing's sarcoma with cutaneous metastasis--a rare entity: report of three cases.
Ewing's sarcoma (ES) is a small round cell tumor, usually arising from flat bones and diaphyseal region of long bones. It is commonly found in the first two decades of life. It is curable when diagnosed in the localized stage and requires multimodality treatment. ES is a chemosensitive tumor. It metastasizes commonly to lung, pleura and other bones. Less common sites of metastasis are lymph nodes, CNS and liver. Skin metastasis is extremely uncommon. It occurs in up to 9% of all patients with cancer. Growth pattern of cutaneous metastasis is unpredictable and may not reflect that of primary tumor. We hereby report three cases of Ewing's sarcoma that developed skin metastasis.
