Synchronous primary heart liposarcoma and papillary renal carcinoma--a case report.

A case of synchronous primary cardiac dedifferentiated liposarcoma and papillary renal carcinoma is presented. The occurrence of typical areas of round cell liposarcoma made the pathological diagnosis of the sarcoma relatively easy; however the neoplasm was not diagnosed correctly before the autopsy. Cardiac liposarcoma is a very rare primary malignant neoplasm and its diagnosis based on image procedures may be extremely difficult especially at non-advanced stage of disease.

Pulmonary infiltrates with masto- and lymphocytosis in BALF associated with arechine.

Pulmonary infiltrates developed in a 40-year-old man while receiving arechine. The hyperplasia of mast cells, hyperlymphocytosis, a predominance of cytotoxic T-cells of the CD8 type with the very low CD4/CD8 ratio in BAL were observed. The chest roentgenogram findings resolved within a month after discontinuing arechine therapy.
