We report on a 7 year-old-girl with mandibulo-acral dysplasia. When she was
3 years of age it mimicked scleroderma because of skin atrophy and later o
n a Hutchinson-Gilford progeria syndrome (HGP). Acro-mandibular dysplasia w
as diagnosed because of facial hypoplasia and mandibular hypoplasia. The bi
lateral proximal mid-humeral notch seen in this case is unusual.
