The article focuses on the case of a 14 year-old girl diagnosed with rhabdomyolysis, which is a rare presentation of hypokalemia. The patient based on initial assessment was diagnosed with rhadomyolysis after being seen with weakness of lower limbs, increased creatinine phosphokinase and mild tubulopathy. The patient underwent a right-sided total adrenalectomy, in which the tumor was encapsulated similar to that of the adenoma macroscopically. This case is the first of adrecortical adenoma with rhabdomyolysis to be recorded in a child.
