[A case of primary cryptococcosis of the lung].
A 37-year-old man was pointed out having an abnormal shadow in the right lung field at a medical checkup in July 1992. There was 5-year life history of rearing about 60 macaws since 10 years before. Upon operation a tumor 1.5 cm in diameter was palpated in the right S6. Intraoperative frozen section diagnosis revealed no malignancy. Partial excision was performed. The excised specimen showed a 1.5 x 1.4 x 1.0 cm, well-defined and yellowish white tumor. Histologically it was granuloma with a thin fibrous capsula, and most of the granuloma necrotized involving cryptococcus formans. Postoperative serum cryptococcus antigen and antibody titers were negative. There has been no sign of recurrence, as of 8 months after the operation. No adjuvant chemotherapy has been needed.
