A case of a giant solid and cystic tumor of the pancreas (SCT) is reported. A 58-year-old man presented with an abdominal mass. Upon admission he showed an increase in the abdominal mass and loss of appetite. The mass was solid but elastic soft, 24×19×8 cm in size and located in the body of pancreas, and showed a fibrous capsule at the operation. Microscopic examination revealed that the mass was solid with a pseudorosette pattern. Immunocytochemical examination revealed that it was positive for the epithelial marker. With these findings a solid and cystic tumor of the pancreas was diagnosed. SCT usually occurs in young women, but our patient was a middle-aged man. Among the 139 reported cases of SCT in Japan, this patient was the oldest and had the largest tumor. Because of the patient's refusal to have surgical intervention four years earlier at a previous admission, observation and calculation of the 240-day doubling time was obtained. This observation indicated that the SCT was a slowly growing tumor. The patient is alive and in good condition after his surgery one year earlier.
