A Rare Case of Cutaneous Metastasis of Osteosarcoma

Abstract

Osteosarcoma (OS) is a primary bone tumor, usually seen in childhood or adolescence. With an estimated incidence of 5 in every 100,000 new cases detected per year, OS is an aggressive malignant mesenchymal tumor. The most common sites for this tumor are the distal end of the femur and the proximal tibia. Metastases from OS are most commonly seen in the lung or other bones. Patients with skin and subcutaneous tissue metastases are a relatively rare subset. Here, we report a rare case of an 18-year-old girl who presented to the hospital with an unusual site of metastasis from OS.
