Lesão de Morel-Lavallée: relato de caso

Abstract

The injury of Morel-Lavallée, first described in the nineteenth century by the French surgeon Victor Auguste François Morel-Lavallée, is a soft tissue injury, particularly in the linimg areas of the bony prominences. The patophysiology consists in the displacement of the skin and the fascia subcutaneous tissue caused by sudden and intense shear forces, secondary to trauma. In the space created by tissue avulsions acumulates blood, lymph and fatty debris. Diagnosis is based on clinical history, physical examination and imag ing studies. Treatment is usually conservative and the prognosis is good, in the minor injuries. In cases of extensive lesions the result can be serious complications. The differential diagnosis includes bursitis, hematoma, abscess, benign and malignant neoplasms. This report aims to alert the pediatrician about the diagnostic possibility of Morel-Lavallée lesion nsuring their early and appropriate approach, especially when we consider the practice of sports, increasingly common among children and adolescents, and the risk of their occurrence of traumas associated with own play activities of pediatric patients.
