Hematoma in a latissimus dorsi donor site 21 months after surgery.

Following strenuous upper extremity exertion, a 40-year-old man experienced pain and swelling in a latissimus dorsi donor site 21 months following harvest and microsurgical transfer of the muscle. Examination and aspiration proved the mass to be a hematoma, and 595 cc of blood were evacuated with resolution of swelling. Late hematoma in a latissimus dorsi donor site must be distinguished from ventral hernia and can be managed by aspiration.
