[Lumbar Morel-Lavallée lesion caused by a minor trauma]

The Morel-Lavallée lesion (MLL) is a closed internal degloving lesion caused by a significant soft-tissue injury, which separates the skin and subcutaneous tissue from the underlying fascia. The separation creates a potential blood-filled cavity, which can become a source of chronic pain. Although the diagnosis of MLL in the greater trochanter and proximal thigh is well established, its occurrence in the lumbar area is unusual. This case report presents a 19-year-old very adipose woman with lower back pain due to a long-standing MLL, and our purpose is to increase the awareness of MLL in the lumbar area.
