Pulmonary metastases, an occult prostatic adenocarcinoma and delayed administration of antiandrogens.

The presentation of prostatic carcinoma with pulmonary metastases is unusual. The patient reported here presented with nodular lung metastases from an unknown primary site and 3.5 years later became symptomatic with a prostatic carcinoma. Subsequent hormonal therapy led to radiological regression of the pulmonary metastases. This case report demonstrates the progression of asymptomatic prostatic lung metastases with time and their response to delayed hormonal therapy, which is discussed.
