[Littoral cell angioma: a rare vascular splenic tumor].

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