Case Report: Achilles Tendon Reconstruction after Epithelioid Sarcoma Resection

In this case report, a 55-year-old woman presented with a lump on her Achilles tendon. An MRI showed the lump to be 5 × 2,5 × 2 cm in size with invasion of the anterior fat tissue. No invasion of the surrounding bones was noted.

An excision of the tumor and reconstruction of the tendinous defect with peroneus brevis transfer was performed.

Epithelioid sarcoma is not typically found on the Achilles tendon and can be easily misdiagnosed as another soft tissue mass. Due to the large tendon defect remaining following wide resection it can be challenging. The authors report that appropriate structural continuity and resistance can be restored with reconstruction with peroneus brevis transfer, reinforced with medial gastrocnemius fascia and plantaris tendon.
