RESUMO
Neuroendocrine Tumors (NETs) encompass a wide variety of tumors arising from neuroendocrine cells, which produce bioactive substances. The incidence of NETs increased significantly lately, becoming one of the most common tumors of the digestive tract. Their clinical presentation is as diverse as their capacity for hormone production. Carcinoid syndrome is the most common hormonal syndrome produced by NETs and is characterized by diarrhea, flushing and cardiac valvular lesions. New research brought multiple changes in the classification of these neoplasms and a new understanding about their diagnosis and treatment, promoting a multidisciplinary approach. Somatostatin analogues, radiation, biological, and cytotoxic drugs have improved the prognosis of these patients, which entails a great challenge for healthcare providers.

Rhabdomyolysis (RD) is the process that leads to cell destruction of striated muscle. Causes include inherited metabolic defects or acquired disorders. RD is frequently associated with acute kidney injury (AKI) and disorders of calcium metabolism. We report a 33 year old man that after amphetamine consumption and an uninterrupted 3,000 km driving presented vomiting, muscle pain and dark urine. He had elevated creatinkinase levels, severe hypocalcemia and an acute renal failure. He was treated with hemodialysis and calcitriol. He was transferred to our hospital and on admission a serum calcium of 18 mg/dl was detected. He continued on hemodialysis, recovering renal function and with normalization of creatinkinase levels and serum calcium level.
