INTRODUCTION: Nontuberculous mycobacteria-related hypersensitivity pneumonitits (NTM-HP), otherwise known as hot tub lung, is an uncommon disease produced by exposure to aerosolized hot tub water containing nontuberculous mycobacteria. Patients usually present with nonspecific, prolonged respiratory symptoms and require a thorough respiratory workup, including radiography and even pulmonary biopsies.

CASE PRESENTATION: We present the case of a 58-year-old patient with chronic respiratory symptoms and history of exposure to a hot tub.

DISCUSSION: There is little data on why certain patients develop NTM-HP; however, it seems to be an immunologic response to the nontuberculous mycobacteria, not a primary infection. The treatment, as in this case, is typically just hot tub avoidance.

CONCLUSION: To our knowledge, this is the first case of NTM-HP reported from Wisconsin. NTM-HP can mimic nontuberculous mycobacterial disease and should be on the differential diagnosis for patients with unclear chronic respiratory problems.
