A tangential contusion on certain regions of the body can lead to a clear or translucent serous subcutaneous collection that appears suddenly or slowly, known as Morel-Lavallée dissecting hematoma. It is frequently located in the hip and infrequently in the knee. The Morel-Lavallée lesion can be called pseudocyst, soft tissue posttraumatic cyst, or Morel-Lavallée extravasation. We present the case of a 49-year-old patient with a serous Morel-Lavallée lesion, caused by friction between the subcutaneous cellular tissue and the fascia during a traumatic injury. Given its infrequent location, it was decided to report this case, since few cases of patients with this condition have been published in the literature.

Palabras clave : Morel-Lavallée hematoma; seroma; soft tissue injury.
