Chronic expanding hematoma in the stumps of persons following transfemoral amputation: A report of two cases.

Abstract

Two persons presented with severe stump pain following transfemoral amputation. A 21-year-old female and a 31-year-old male with transfemoral amputation were ambulatory with prostheses and suffered from severe stump pain caused by the presence of masses around the tip of the bone stump. From the clinical courses, imaging studies, and the intraoperative findings, the masses were diagnosed as a relatively rare condition known as chronic expanding hematoma. The two patients were treated successfully with surgical resection. The hematomas were soft cystic masses with a thick capsule containing old blood clots and serous fluid. There were no pathological signs of malignancy. After surgical treatment, the patients achieved walking without stump pain. Although chronic expanding hematoma is a rare condition, it should be considered as a possible cause of stump pain. Stump pain is caused by many conditions. Although chronic expanding hematoma is a rare condition, it should be considered as a possible cause of stump pain.
