ABSTRACT
BACKGROUND: Acinar cell carcinoma (ACC) is a rare malignancy of the pancreas arising from acinar cells. Unlike ductal adenocarcinoma, this tumor rarely presents with pancreatitis. METHODS: We present a case of ACC associated with chronic calcifying pancreatitis, and a review of the literature focusing on diagnosis and management. RESULTS: A 43-year-old man was proposed for Wirsungojejunal derivation for chronic pancreatitis. Histopathological examination of the tissue extracted revealed an ACC. Duodenopancreatectomy was performed. Six months post-operatively, the patient developed hepatic metastasis and was treated with gemcitabine as palliative chemotherapy. CONCLUSIONS: The clinical presentation of ACC of the pancreas is not specific and the tumor can be under-diagnosed when associated with chronic pancreatitis. Data regarding course, treatment, and prognosis of this tumor are generally lacking.

AIM: The aim of this study is to review clinical data, histological and immunohistochemical findings and prognosis of stromal gastrointestinal tumors. METHODS: A retrospective Study of 32 cases of stromal gastrointestinal tumors diagnosed in the Department of Pathology of Mongi Slim Hospital of Tunis from 1991 to 2004. RESULTS: The average age of the patients was of 54.4 years, equal for sex. Tumors were essentially gastric (50%) and of the small intestine (37.5%). All the patients had surgical treatment. Gastro-intestinal Stromal Tumors or GIST represent the most frequent stromal tumor with 56.2% of cases. CONCLUSION: After immunohistochimestry study, using CD117 antigen, this revision allows better management of GIST. Glivec is the standard treatment of advanced GIST.
