Littoral cell angioma is a rare primitive vascular tumor of the the spleen considered as benign. Its clinical presentation is non specific. The diagno stic is based on histological and immunohistological analysis. The lesion i s composed of anastomosing vascular channels often featuring papillary proj ections. They are lined by tumoral cells which exhibit an immunoreactivity for vascular and histiomonocytic markers. We report one case of littoral ce ll angioma and we discuss the diagnosis and the histogenesis of this tumor.
