<unk>  is a mesenchymal dysplasia manifesting as regions of dripping wax appearance or flowing candle wax appearance. The disorder can be detected by radiograph due to thickening of bony cortex resembling "dripping candle wax." It is included on the spectrum of developmental bone dysplasias including pycnodysostosis and osteopoikilosis. The disorder tends to be unilateral and monostotic (i.e. affecting a single bone), with only one limb typically involved. Cases with involvement of multiple limbs, ribs, and bones in the spine have also been reported. There are no reported cases of involvement of skull or facial bones.<unk>  can be associated with pain, physical deformity, skin and circulation problems, contractures, and functional limitation. It is also associated with a benign inner ear dysplasia known as osteosclerosis.
