Hot tub lung is a form of hypersensitivity pneumonitis (HP) reported to be associated with exposure to large aerosolized inocula of Mycobacterium avium complex (MAC). Although the pathogenesis of the disease is still poorly understood, the pathology of MAC-related HP can be similar to that of sarcoidosis, with well-formed granulomas. We describe a patient with HP featuring well-formed granulomas on transbronchial biopsy specimens, a finding believed to be unique to MAC-related HP, also referred to as "hot tub lung".
