Morel-Lavallée lesion (MLL) is a type of degloving injury.[2] Generally it occurs around the thigh or pelvis; though other areas may be involved.[2] Symptoms may include bruising, increased skin mobility, and swelling.[2] This may not appear for a couple of days.[2] Complications may involved infection or an abnormal shape to the area.[2]
It most commonly occurs as a result of significant trauma, such as a motor vehicle collision.[2][1] Associated injuries may include breaks of the pelvis or femur.[2] The underlying mechanism involves separation of the subcutaneous tissue from the fascia underneath, without a break in the skin.[2] This creates a space in which fluid collects.[1] Diagnosis is based on examination and may be supported by medical imaging.[2]
Management typically involve closely watching, drainage using a needle, or surgery.[2] Other options may include compression therapy or sclerotherapy.[1] After treatment their is a risk of occurrence.[1] Morel-Lavallée lesions are relatively rare.[1] It was first described in 1863 by Victor-Auguste-François Morel-Lavallée.[2]
