Dual paraneoplastic syndromes in a patient with small cell lung cancer: a case report.
Paraules clau
Resum
BACKGROUND
We describe the case of a patient with small cell lung cancer and dual paraneoplastic syndromes involving adrenocorticotropic hormone and calcitonin. To the best of our knowledge, dual paraneoplastic syndromes involving these two hormones have not been previously reported in the literature.
METHODS
A 74-year-old Caucasian woman presented with a left hilar mass and metastatic disease in the liver and right adrenal gland. The patient complained only of intermittent diarrhea. Her laboratory values exhibited metabolic alkalosis with hypokalemia, hypocalcemia, hypomagnesemia, hypophosphatemia, and hyperglycemia.
CONCLUSIONS
We discuss the work-up and treatment of the patient's unusual laboratory presentation with two concurrent paraneoplastic syndromes.
