title: Diffuse pulmonary tumor microemboli from prostatic carcinoma with an associated fibrous histiocytic sarcoma.
abstract: Diffuse tumor microemboli to the lungs from prostatic carcinoma are extremely rare, with only six reported cases in the literature published in English. Here a seventh case is reported. The patient resembled the previously reported cases in the following ways: (1) There were minimal chest x-ray findings; (2) there was no other evidence of significant parenchymal or lymphangitic tumor involvement; and (3) pulmonary hypertension developed, but without signs of cor pulmonale. The case was even more unusual because of the presence of an apparent second neoplasm, ie, a malignant fibrous histiocytic sarcoma primary in the chest wall. There were wide-spread "collisional metastases" (metastases from each malignancy at the same site).
