Adult-Onset Pancreatoblastoma.

Pancreatoblastoma (PB), an extremely rare malignancy of the pancreatic tissue, comprises less than 1% of all pancreatic tumors. Owing to the rarity of the malignancy and the potential for multiple differential diagnoses, adult-onset PB can be challenging to diagnose. The hallmark characteristic in diagnosing adult PB is found histologically. In approximately 90% of cases, squamous corpuscles are observed. We present the case of a patient diagnosed with adult-onset PB, who presented with key clinical and pathological features, as well as rarer characteristics, associated with the malignancy.
