A Rare Presentation of a Common Disease: A Case Report.

Addison's disease (AD), or primary adrenal insufficiency, was first described by Thomas Addison in patients with adrenal tuberculosis (TB). Over the past several decades, along with the introduction of antituberculous treatment (ATT), the incidence of both has declined. The most common symptoms are nonspecific, leading to delayed diagnosis; patients may first present with a life-threatening crisis. Here, we report a case of AD that, upon further workup, was found to be due to one of the most common infections in India-TB.
