Morel-Lavallée lesion (MLL) is a type of degloving injury. Generally it occurs around the thigh or pelvis; though other areas may be involved. Symptoms may include bruising, increased skin mobility, and swelling. This may not appear for a couple of days. Complications may involved infection or an abnormal shape to the area.

It most commonly occurs as a result of significant trauma, such as a motor vehicle collision. Associated injuries may include breaks of the pelvis or femur. The underlying mechanism involves separation of the subcutaneous tissue from the fascia underneath, without a break in the skin. This creates a space in which fluid collects. Diagnosis is based on examination and may be supported by medical imaging.

Management typically involve closely watching, drainage using a needle, or surgery. Other options may include compression therapy or sclerotherapy. After treatment their is a risk of occurrence. Morel-Lavallée lesions are relatively rare. It was first described in 1863 by Victor-Auguste-François Morel-Lavallée.
