title: [Pulmonary Mycobacterium Avium-Complex (MAC) Disease Differentially Diagnosed from Metastasis of Testicular Cancer : A Case Report].
abstract: A 45 year-old-man was admitted to our hospital because of discomfort in his left scrotum. He had a left testicular tumor. We performed high orchiectomy and pathological findings revealed testicular cancer. He was treated with bleomycin, etoposide and cisplatin. Computed tomography showed a new mass in the left lung after 3 cycles of the chemotherapy. Because of its rapid growth, the tumor was thought to be a metastasis lesion of testicular cancer or pulmonary infection. Transbronchial lung biopsy showed an invasion of multinucleated giant cells and granuloma. The culture and polymerase chain reaction of the bronchial sputum were positive for myobacterium avium-complex (MAC). From these findings, the left lung tumor was diagnosed as pulmonary MAC disease. He received partial resection of the left lung and the lesion was diagnosed as granuloma. There was no recurrence of testicular cancer or pulmonary disease after the surgery.
