RESUMO
BACKGROUND: Rhabdomyolysis can be the result of vigorous physical activity. Typical signs and symptoms at presentation are muscle pain, weakness, or dark colored urine. There is no scientific literature associating rhabdomyolysis with gynecologic signs and symptoms. CASE: We present a case of a 16-year-old girl who presented to our pediatric emergency department with complaints of progressive left vulvar swelling. The patient underwent magnetic resonance imaging, which showed polymyositis in the rectus abdominus, external and internal obliques, and bilateral vastus lateralis muscles. Laboratory evaluation showed elevated liver transaminases, creatine kinase, and myoglobin serum levels. SUMMARY AND CONCLUSION: Exertional rhabdomyolysis is associated with muscular damage after vigorous exercise. This case is an example of a patient with rhabdomyolysis presenting with an unusual external gynecological manifestation, as unilateral labial edema.
