Heel pain due to psoriatic arthritis in a 50 year old recreational male athlete: case report.

Heel pain is a common presentation in a sports injury practice, with a list of common differentials including achilles tendinopathy and retrocalcaneal bursitis. However, seronegative arthritis can also cause enthesopathies that produce heel pain and should be considered in a differential diagnosis list. In this case, a 50 year old recreationally active male presented with non-traumatic insidious heel pain and without history of any skin conditions or any other symptoms of seronegative spondyloarthritis. Clinical suspicion led to laboratory testing and radiographs/bone scan which yielded the diagnosis of psoriatic arthritis.
