“…The excess of ceroids that gives rise to sea-blue histiocytes has been observed in widely differing diseases, for example in conditions with massive cell destruction, chronic myeloid leukaemia (Sundberg era/., 1964; Kattlove er a/., 1969;Lee& Ellis, 1970;Dosik, Rosner & Sawitsky, 1972), thronibocytopenia (Landing et al^ 1961;Saltzstein, 1961;Hill, Speer & Gedrikoglu, 1963;Dollberg et al., 1965;Quinton, Wurzel & Czernobilsky, 1967;Couderc et al, 1969;Cazal et al, 1971;Quattrin et al, 1972), hyperlipoproteinaemia of type I (Ferrans et ai^ 1971) or type V (Rywlin et al, 1971b), dysUpidosis (Terry, Sperry& Prodoff, 1954;Kristenson & Sourander, 1966;Lowden, Barson& Wentworth, 1970), albinism with hypocholesterolaemia (Maranoff, Fite and Frumin, 1972) and lecithin cholesterol acyltransfcrase deficiency (Jacobsen, Gjone & Hovig, 1972). This feature has been found also in cases of chronic granulomatous disease (Ford et al, 1962;Bartman, van dc Velde & Friedman, 1967) and of rupture of the spleen (Winkler et al, 1969) and in siblings with splenomegaly and neurological disorders (lones et al, 1970;Lake, Stcphans and Stephans, 1970).…”
