- Ceroid: benign histiocytes with abundant, foamy, vacuolated cytoplasm due to ingestion of sphingomyelin and other phospholipids
- Sea blue histiocyte syndrome (OMIM: Sea Blue Histiocyte Disease [Accessed 2 March 2018]): autosomal recessive, may be related to adult Niemann-Pick disease (Hum Pathol 1982;13:1115)
