Published: July 2015

Background: Morel-Lavallée (ML) lesions are closed degloving injuries described as posttraumatic subcutaneous fluid collections. They are most commonly seen in the proximal thigh. They can present several days to months after the inciting event.

Case Report: A 55-year-old woman with a recent admission for trauma presented to the Emergency Department with increasing swelling and pain in the right thigh for the previous 3 days. Ultrasound of the thigh was negative. Magnetic resonance imaging performed to further evaluate for leg swelling revealed a "Morel-Lavallée lesion" of the thigh that required drainage. The patient recovered completely after the surgery. WHY SHOULD THE EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should be aware of these rare lesions because they are often mistaken for tumors or hematomas. Early recognition may avoid subsequent complications and help in obtaining prompt specialist care.

BACKGROUND Perineal injuries affecting the scrotum and penis are rare in pediatric patients, owing to the protective anatomy of the male genitalia. However, when such injuries do occur, timely surgical intervention is crucial. This kind of damage might not be life-threatening but could cause functional disorders and have a huge impact on the patients' psychological condition if not treated appropriately, especially as they enter puberty.

Background: Degloving soft-tissue injuries are underreported in Sudan and are potentially devastating. They require early recognition and diagnosis with early and systemic management to reduce the complications that may arise, and to minimize delay for proper intervention by a multidisciplinary team that is usually needed to ensure the effective rehabilitation of these patients and a better outcome.

Objective: To assess the degloving soft tissue injuries of the upper limb and their management in Khartoum.

Death by collision with an incoming train is common in countries where a railroad network exists. In such cases, when there is severe pelvic trauma, the penis may be partially degloved and turned inside out. The inverted penile skin may then resemble a vulva and the scrotum may mimic labia majora, causing the injured male genitalia to strongly resemble female genitalia.

Salvage of Circumferential Multiplane Degloving Injury of Hand with Single Viable Finger - Case Report.

J Orthop Case Rep

November 2024

Department of Trauma and Orthopedics, Hand and Microsurgery Unit, Rashid Hospital, Dubai Health, Dubai, United Arab Emirates.

Introduction: Circumferential multiplanar degloving injuries of hand and wrist are devastating injuries which can severely compromise what is salvageable for achieving a functional hand, ending in amputations if not well managed.

Case Report: We described a complete multiplanar degloving injury of hand in a 27-year-old Asian male due to a compressing machine, which was successfully salvaged with a complete free latissimus dorsi flap cover with skin graft for coverage.

Conclusion: An unconventional one-stage surgical option for soft-tissue coverage using a complete latissimus dorsi free flap ending in a reasonably functional two-fingered hand.
