Résumé
It is a rare tumor characterized by a good prognosis even in metastatic cases. Its etiopathogenesis is still controversial and the anatomopathological progress permits for the best comprehension of these tumors. It's a case revealed by an abdominal pain witch the diagnosis was done by a histological study aided by an immunohistochemistry analysis of the excised tumnor. This pathology represents 0.7 to 2.7% of all cases of the exocrine tumors of the pancreas, with a female predominance and the average age is 22 years old. The clinical picture is not specific and may be discovered by chance. The diagnosis is based on histological study. It shows a tumoral proliferation of a pseudopapillary shape composed of small sized cells adherent to the fibrovascular axes. The differential diagnosis between these tumors and essentially the neuroendocirne tumors is based on the immunohistochemistry analysis. The treatment is essentially surgical with a good prognosis even with metastatic cases. The diagnosis of solid pseudo-papillary tumor of the pancreas bases on histological study aided by an immunohistochemistry analysis. Its good prognosis justifies a surgical radical treatment. The visible increase of its incidence is the likely consequence of a better knowledge of this pathology
