Étude ultrastructurale des histiocytes bleu marine dans une lipidose splénique idiopathique avec surcharge en céroides

An ultrastructural study was performed in a patient with spleen lipidosis with ceroid overload. The different inclusions observed in histiocytes of the pulp rods are described. According to the lesions observed three types of histiocytes are differentiated with sequential evolution starting with phagocytosis of blood cells and ending with overload of ceroids. The latter is characterized by true myeline figures related to the granules observed optically in the blue histiocytes.
