Incidence of metastatic disease to the hypothalamic-pituitary area is low (1 to 6% in most studies), the lung and the prostate being the most common primary sites in men. Clinical presentation as panhypopituitarism is rare (0.2 to 0.8%) in patients with bronchogenic carcinoma. The authors describe a case of a man with diagnosis of squamous cell carcinoma of the lung that, during the clinical course of the disease, presented clinical and laboratorial evidence of panhypopituitarism, with an expansive sellar and supra-sellar lesion image in the CT scan of the brain.
