Albright's hereditary osteodystrophy (AHO) is a syndrome which combines pseudohypoparathyroidism (secondary to end-organ resistance to PTH), decreased calcium, increased PO4, short stature, obesity, round face, and brachydactyly. The main skin finding is bone formation (osteoma cutis--OC). In contrast to actual hypoparathyroidism, the PTH level is normal or even increased.
The lesions of osteoma cutis may occur anywhere, but have a predilection for sites around large joints and areas of trauma. The lesions initially may be pinpoint in size and then enlarge, e.g., becoming 5-8 cm in size. Shortening of the metacarpal bones may occur in patients with AHO.
With regard to treatment of the osteoma cutis, see osteoma cutis.
