The Morel-Lavallée lesion (MLL) is a closed soft-tissue degloving injury, resulting in characteristic hemo-lymphatic fluid collection between the fascia and subcutaneous layers. The MLL was managed routinely with drainage and compression bandages, but sclerotherapy can be used in patients with chronic lesions refractory to first-line therapy. This paper presents a case of extensive recurrent chronic MLL treated with sclerotherapy using Abnobaviscum, which has been used to treat adhesion in malignant pleural effusion.

(A) Magnetic resonance image shows fluid collection (28 cm×5 cm×2 cm; arrow) between the fascia and the subcutaneous layer on postoperative one month. (B, C) After eight months of conservative treatment, magnetic resonance was repeated, showing persistent fluid collection (32 cm×3 cm×6 cm; arrows) with thick enhancing fibrous capsulation.

(A) Intraoperative appearance of Morel-Lavallée lesion at the left thigh. (B) It was surrounded by thick fibrous capsulation and excised during debridement. (C) The vacuum-assisted closure system was applied to the wound after secondary debridement. (D) After repeated debridement and change in the vacuum-assisted closure system for one week, Abnobaviscum (Abnoba Korea) was administered as a sclerosing agent on an open wound.
