Epidemiology Cherubism is a very rare disorder with only an estimated cases reported in the literature. Cherubism cannot be diagnosed by histology alone because they are not distinguishable from other giant cell lesions of bone [ 45 ]. However, when performed, numerous osteoclast-like multinucleated giant cells in a moderately loose fibrous stroma are present. The arrangement of primary teeth can be disturbed [ 2425 ]. Hum Mutat. An excess of these bone-eating cells contributes to the destruction of bone in the upper and lower jaws.

    Cherubism with co-expressed craniosynostosis and clubbed fingers has been described in a single family [ 1516 ], However, it is not clear whether the appearance of these phenotypes is coincidental or associated with cherubism.

    Dental disease involving the jaw K07—K10— It has been noted that the condition does not progress beyond puberty. The classic clinical appearance of the cherubic face includes bilateral, symmetric, painless fullness of the cheeks and mandible in children at 2 to 7 years of age, when the diagnosis of cherubism is usually made.

    In mouse models with mutant or ablated Sh3bp2 genes [ 283031 ] there is a delayed B-cell response [ 31 ].

    Additional information Competing interests The authors declare that they have no competing interests. When expansile fibrous tissue masses invade the floor and walls of the orbits they can cause upward tilting or displacement of the globes.

    The orbital effects of cherubism are due to this displacement and not to direct invasion of the globe and surrounding extraocular muscles. Details of histological findings at the various stages of cherubism are rarely described. The impact of cherubism lesions on development and eruption of the primary and permanent dentition varies depending on the time of onset and severity of the expansile lesions.
