In this paper we report two patients with asymptomatic hypercalcemia, one with primary and the other with ectopic hyperparathyroidism, in whom cytologic examination of the sputum led to the diagnosis of carcinoma of the lung despite the presence of normal chest roentgenograms. Sputum cytology is a simple, inexpensive and accurate test which should be included in the diagnostic regimen for hypercalcemia.
在本文中，我们报告了两名无症状高钙血症患者，一名患有原发性甲状旁腺功能亢进，另一名患有异位甲状旁腺功能亢进，尽管胸部X线片正常，但痰细胞学检查却诊断出肺癌。痰细胞学检查是一项简单、廉价且准确的检查，应纳入高钙血症的诊断方案中。
