History of Present Illness

An 82-year-old woman from Colorado was referred because of progressive shortness of breath over the past year. Her primary care physician had prescribed Trelegy® which did not improve her dyspnea. An outside pulmonologist noted abnormal findings on her thoracic CT scan and a bronchoscopy with bronchoalveolar lavage (BAL) was preformed which was positive for Mycobacterium Avium Complex (MAC). She was treated with a 3-drug regimen (azithromycin, rifampin, ethambutol) for 6 months with mild improvement. After the treatment was stopped, she noted more dyspnea and required supplemental oxygen. She underwent a fundoplication and initially improved but a month later her shortness of breath seemed to worsen. She was started on prednisone which was tapered to 10 mg/day. She was referred to the Mayo Clinic for possible VATS lung biopsy.

Our patient is a 76-year-old gentleman  who was referred based on an abnormal CT scan. He has a history of metastatic melanoma and had begun immunotherapy with pembrolizumab 10 months prior to admission. He had low grade fevers and chills and some dyspnea on exertion and dry cough. He also had a 6-8 pound weight loss over 4 weeks.

PMH, SH and FH

He has a history of hairy cell leukemia since 2009; squamous and basal cell cancers; and diabetes on insulin. He is a retired commercial banker and has a 15 pack-year smoking history.
