One case of papillary cystic tumor of the pancreas was reported in young woman aged in 30. She was visited at OPD because of palpable neck mass. But, during the physical examination, large abdominal mass was palpated and reexamining this palpable mass was started. Sonography and abdominal CT revealed a well demarked cystic and solid mass. This tumor was treated by partial pancreatectomy. measuring diameter was 17x11x8 cm. Gross pathologic examination revealed apparent encapsulation, cystic degeneration, and hemorrhagic necrosis. Microscopically, the tumor is cellular with hemorrhage and the tumor was composed of papillae, solid growth and cystic pattern of proliferating epithelial cell. This epthelial cells are rather uniform and have small ovoid nuclei with indistinct nucleoli and vacuolate or pale eosinophilic cytoplasm. Unlike most pancreatic tumor, these are either or of relative low grade malignant potential and thus are amenable to surgical resection and cure. It is important to distinguish this rare tumor from other pancreatic tumor with similar cytohistologic future. Since, if correct diagnosis and surgical managed, this tumor was curable.
