Calcifying aponeurotic fibroma around Achilles tendon: A case report

Calcifying aponeurotic fibroma is an uncommon benign fibrous tumor, typically develops around the fascia and tendons and commonly observed in children and adolescents. It usually occurs in the distal portion of the extremities. Presented as slow growing painless mass, treated with complete surgical excision with high recurrence tendency. We report a case of calcifying aponeurotic fibroma in a 4-year-old girl located posterior to Achilles tendon. Clinical, radiographic, and magnetic resonance imaging findings are described. To the best of our knowledge, this is the first reported case of CAF located posterior to Achilles tendon.
