Syndrome of Inappropriate Antidiuretic Hormone Presenting with Recurrent Hiccups in a Case of Small Cell Neuroendocrine Carcinoma of the Lung with Concomitant Pulmonary Tuberculosis

Abstract

Tuberculosis (TB) and lung cancer are the leading causes of mortality and morbidity in the world. The burden of TB is significantly high in developing countries causing serious public health concern, and the incidence of lung cancer is also increasing all around the world with high mortality. Pulmonary TB coexisting with lung cancer can mask the underlying disorder producing diagnostic dilemma resulting in a delay in diagnosis leading to decreased survival of the patients. Here, we report a rare case of a 66-year-old male diagnosed with microbiologically confirmed TB along with coexisting small cell neuroendocrine carcinoma of the lung presenting with syndrome of inappropriate antidiuretic hormone.
