Abstract:
We report a resected case of malignant lymphoma with hypersensitivity pneumonitis. A 62-year-old woman, who presented with fever, wheeze and dry cough was referred to our department under the diagnosis of malignant B cell lymphoma in lower lobe of the left lung and hypersensitivity pneumonitis. She underwent left lower lobectomy as a therapy for malignant lymphoma. Pathological findings showed multiple small nodules macroscopically, which was observed as bronchiolocentric interstitial pneumonitis with lymphocytes microscopically. Post operative course was uneventful and no sign of acute exacerbation was seen. It is rare that lung with hypersensitivity pneumonitis is observed as a macroscopical specimen. Hypersensitivity pneumonitis differs from idiopathic pulmonary fibrosis, but we have to take care of post operative course because post operative acute exacerbation was reported.
