Primary carcinoid of the prostate in conjunction with multiple endocrine neoplasia IIb in a child.

Prostatic neoplasms are rare in childhood. We report a case of primary prostatic carcinoid in a 7-year-old boy who was subsequently diagnosed with multiple endocrine neoplasia IIb. To our knowledge this is the first report of either pediatric carcinoid of the prostate or of prostatic carcinoid in conjunction with neuronal intestinal dysplasia and medullary thyroid carcinoma suggestive of multiple endocrine neoplasia IIb. Management and histogenesis regarding this prostatic tumor are discussed as is a possible association with other neuroendocrine tumors.
