Calcaneal Osteosarcoma in a Patient Referred for Plantar Heel Pain.

A 28-year-old man was referred to physical therapy from his primary care provider with variable and intermittent left lateral plantar heel pain that began insidiously about 10 months prior. Radiographs of the foot and ankle were completed prior to the physical therapy evaluation and interpreted as noncontributory. Because his pain and function were minimally improved after 4 weeks, the patient was referred for magnetic resonance imaging. An abnormal mass in the calcaneus prompted an urgent referral to an orthopaedic oncologist. Percutaneous biopsy confirmed a diagnosis of calcaneal osteogenic sarcoma.
