Solid-pseudopapillary tumor or papillary cystic neoplasm of the pancreas accounts for 1-2% of non-endocrine tumors of this organ. First described in 1959, it is more common among young women. Tumor symptoms - loss of appetite, vomiting, nausea, low back pain, compression on adjacent organs are characteristic. Sometimes clinically silent tumor, can be found during clinical investigations. Macroscopically, the tumor is encapsulated, often localized in the tail and body of the pancreas. Vascularized solid-cystic structures with pseudo-papillary formations are characteristic. The histogenesis of the tumor is unknown. For 5 years out of 39 cases of pancreatic pathology, two cases (5.0%) of solid pseudopapillary tumor were revealed. Both patients were female. In both cases, a radical operation was performed. Based on histopathological and immunohistochemical studies, the solid-pseudopapillary tumors of the pancreas were established. The verification of the diagnosis needs an immunohistochemical study of biopsy and operational material.
