Solid and papillary epithelial neoplasm of the pancreas is a rare, low grade malignant tumor of adolescence. The tumor we described was diagnosed by following preoperative percutaneous fine needle aspiration biopsy and confirmed by tissue examination. Characteristic cytologic findings were monotonous cells arranged in papillary fronds, acinus, and cords in necrotic and hemorrhagic backgrounds. Occasional foamy histiocytes and hyaline globules were present. The cytoplasm of the tumor cells were moderate in amount, pale eosinophilic or vacuolated with distinct borders. The nuclei were centrally located and round. There were one or two small nucleoli and finely granular chromatin throughout the nucleus.
