Abstract

We present the case of an 81-yr-old man with a prostatic adenocarcinoma and a metastatic carcinoid. Simultaneous occurrence of hormonally treated adenocarcinoma of the prostate and a carcinoid has been described before. The pathogenesis of this coincidence is largely unclear; however, androgen deprivation therapy might play a key role in neuroendocrine differentiation of adenocarcinoma cells. Early recognition of the carcinoid syndrome is crucial, as surgical cure is not possible after metastasis. We provide a brief review of recent literature.
