Introduction: Solid papillary neoplasia of the pancreas (NSPP) described by Frantz in 1959 is a rare lesion, indolent, whose origin has not been elucidated. WHO establishes it as a neoplasm usually benign, with an increase in frequency in recent years. It occurs in young women whose average age is 30 years. Rare cases are reported in men. This study aims to determine the USE pattern of the solid papillary neoplasia and correlate them with the cytological findings of fine needle aspiration (PAAF). Methods: 10 cases were evaluated retrospectively visualized by USE and diagnosed by PAAF as NSP during July 2006 to June 2009. Results: 90% of the cases were female, whose average age was 35.2 years. 90% were single tumors with a predominant tumoral size between 4 to 6 cm in 60%. There was no preference in location. At USE the lesions were thick-walled, 90% mixed echogenic images with hyper and hypoechoic areas, macro, micro-cysts and solid areas, 10% showed calcifications. In 100% of the cases the cytological study presented papillary structures with metachromatic material in chinese characters pattern, cells with uniform nuclei, finely granular chromatin and crevices. Conclusion: PAAF guided by USE is an effective method for diagnosis of the NSPP.
