A rare case of morel-lavallee lesion

Abstract

Morel-Lavallee lesion (MLL) is a closed soft-tissue degloving injury caused by shearing force abruptly separating the skin and superficial fascia from the deep fascia and creating a potential space. Blood, lymphatic fluid, and debris collect and fill the space. The thigh, hip, and pelvic regions are the most commonly affected regions. Apart from the classic location over the region of the greater trochanter, MLLs have been described in other parts of the body. We present the case of a 67-year-old female patient with a past medical history of hypertension presented with a gradually growing swelling of the right gluteal region of 4-week duration, associated with pain on movement and relieved on rest and with no previous history of trauma, pain, or inability to walk. Ultrasonography of the right gluteal region revealed a well-defined localized collection measuring 8.0 cm × 5.1 cm × 2.6 cm with internal septations and few solid components with peripheral vascularity noted in the right gluteal region. Surgical excision specimen of the same was sent for histopathological examination, and a diagnosis of MLL was made. Early diagnosis and management is essential as any delay in diagnosis or missed lesion will lead to the effusion becoming infected or leading to extensive skin necrosis.
