[Small cell carcinoma of the prostate: an autopsy case report].

An 83-year-old man was admitted to our hospital with complaints of dysuria and backache. The patient had been treated with a luteinizing hormone-releasing hormone analogue for 2 years. An enlarged, hard and nodular prostate was palpable on digital rectal examination. Serum level of prostate specific antigen (PSA) was 1.7 ng/ml (0-4) and that of neuron-specific enolase (NSE) were 263.2 ng/ml (0-10). Multiple bone and liver metastases were seen on CT and MRI. After hospitalization, the liver function worsened markedly. The patient died on the 34th hospital day, and was diagnosed with primary small cell carcinoma of prostate on autopsy.
