@entity6196 ( @entity6196 ) of the pancreas is extremely rare. Although the diagnosis of @entity6196 is suggested by the light microscopic appearance of the @entity5 , it should be confirmed by the immunohistochemical evaluation of the @entity517 expression and if possible, further determination of the particular chromosome translocation, t(11;22)(q24,q12). In this report, we present a male @entity1 with pancreatic @entity10476 who had been followed up for 50 months. The related literature is also reviewed. In our case, the pathologic diagnosis was based on the positive immunoreactivity for @entity3778 in many of the @entity5 cells. The complementary cytogenetic studies were not possible in the private setting of the @entity1 's treatment. The @entity1 was 31 years old when first operated. Within 4 months of the first operation he had local recurrence. In the third year of his follow-up he had been discovered to have pulmonary metastases and another @entity3 in his lung was diagnosed the year after. The metastatic foci were primarily treated by surgical resections. He had chemotherapy after each resection of pulmonary metastatic foci. After 50 months of the initial surgical intervention, he succumbed to widespread thoracic and bone metastases. Because of the extreme rarity of @entity10476 in the pancreas, and its rather protracted course, we think our case may further contribute to the ever expanding database for this particular entity.
