Abstract

As a primary malignant bone tumor, osteosarcoma is second only to chondrosarcoma. Although it commonly metastasizes and is aggressive in nature, it rarely colonizes the skin. This is a report of a 22-year-old male with osteosarcoma of the pelvis and metastasis to the lungs and chest wall who developed a clinically unsuspected solitary cutaneous metastasis in the scalp. Instead of the expected cyst, incisional biopsy disclosed a solid tan nodule of chondro-osseous sarcoma. Although rare, cutaneous metastases from osteosarcoma may appear in skin, especially the scalp, or in skin over the primary tumor. New skin lesions in a patient with a history of osteosarcoma warrant investigations including imaging and biopsy.
