Alveolar soft-part sarcoma (ASPS) is a rare soft tissue tumor. Most patients with ASPS present with metastatic disease. The most common sites of metastasis are in the lungs and brain, whereas bone metastases are relatively uncommon.
This case illustrates a rare presentation of metastatic ASPS with foot pain secondary to metatarsal metastasis. Initially, the primary tumor occurred in the left distal thigh. Four years later, brain and lung metastases were found. Another 9 months later, bone metastasis in the right foot was suspected clinically and was confirmed on bone scanning, with additional imaging and histopathology.
