Introduction: Solid-pseudopapillary tumors represent 1 %-2 % of all the pancreatic solid tumors, with low malignant potential.
Series of cases: In the department of pathology at the Universidad de Antioquia were diagnosed sixteen cases between January 2004 and July 2019. Two of those cases were pediatric patients, one male with subsequent hepatic metastasis. Two additional cases were represented by two females older than 40 years old and the rest of the cases were females between 17 and 26 years old. One of the cases had sarcomatoid aspect cells, two others revealed multinucleate giant cells, and one last case of severe pleomorphism and presence of atypical mitoses. Capsule invasion was observed in 6 cases: one of the cases with lymphovascular invasion and the other 3 cases with perineural invasion. All cases showed hemorrhage or necrosis, and the immunohistochemical profile was positive for β-catenin, CD10, progesterone receptors, and CD56. Synaptophysin was focally positive.
