Hereditary osteodystrophy with multiple hormone resistance--a case report.

Hereditary Osteodystrophy, also called pseudohypoparathyroidism, Type 1A (PHP), is a very rare condition composed of a heterogeneous group of autosomal dominant disorders with the common feature of organ resistance to multiple hormones. These patients produce the right amount of hormones but there is resistance to its effect. PHP is difficult to diagnose and the lack of diagnosis may have serious implications for the patient. We report a case of PHP, diagnosed by the dentist, due to the dental and jaw manifestations.
