In existing literature about elastofibroma dorsi (ED), no cases reported ED arising after latissimus dorsi flap harvest. Concretely, we present a patient who developed an ED at latissimus dorsi free flap donor site 10 years after harvesting. After our research, we found the occurrence of ED after thoracotomy surgery, stressing the importance of previous local trauma. Latissimus dorsi flap harvest is also a local traumatic episode, although its association with ED has not been previously reported. Thus, ED should be considered in the differential diagnosis of deep soft tissue lumps after latissimus dorsi harvest.
