A Solid Pseudopapillary Neoplasm in a 10-Year-Old Boy Diagnosed by Endoscopic Ultrasound-Fine-Needle Aspiration (EUS-FNA).

The incidences of pancreatic neoplasms are exceedingly rare during childhood and adolescence. Most common among pancreatic neoplasms are solid pseudopapillary neoplasm (SPN) of the pancreas, a rare pancreatic neoplasm with low malignant potential that occurs predominantly in young females. We present a case of SPN with cytomorphological, immunohistochemical, and also histomorphological findings in a 10-year-old boy diagnosed by endoscopic ultrasound-fine-needle aspiration.
