Apudoma (medical condition): An endocrine tumor arising from APUD (amine precursor uptake and decarboxylation) cells. Often occurs in the pancreas, prostate and ampulla of Vater. They are derived from neural crest cells. As the tumor can arise in a variety of parts of the body, the symptoms will depend on the location of the tumor and the amount and type of hormone secreted e.g. insulinoma, gastrinoma. The term dates back to at least 1975. Because the label "Apudoma" is very general, it is preferred to use a more specific term when possible.


Symptoms may vary considerable depending on the location of the tumor Endocrine anomalies.
