XXXX with lung metastasis diagnosed by lung biopsy.

@entity1 @entity1667 @entity55 @entity5 @entity8302 @entity56
@entity8302 are very rare and account for only 3% of @entity5 and are generally benign. Only less than 0.2% of all @entity5 were evidenced by metastatic spread. We report a 34-year-old @entity1 visited hospital because of coughing sputum mixed with blood. His chest CT showed bilateral patch clouding opacity. He was suspected with @entity56 and treated with @entity1667 . However, his symptoms and general condition deteriorated, and he visited our hospital. He had no abnormal findings on physical examination. A chest radiograph showed @entity55 in whole lung and CT showed multiple nodules and diffused ground glass opacities in both lung fields. Lung biopsy confirmed a diagnosis of @entity8302 with lung metastasis. The diagnosis is based on the histopathology and immunohistochemistry.
