title: Acrodysostosis coinciding with pseudohypoparathyroidism and pseudo-pseudohypoparathyroidism.
abstract: The diagnosis of acrodysostosis has been differentiated from that of pseudohypoparathyroidism or pseudo-pseudohypoparathyroidism by the absence of endocrine abnormalities, more generalized osseous abnormalities, and a characteristic facial appearance. Two cases are presented which fulfill all of the major features of acrodysostosis: peripheral dysostosis, nasal hypoplasia (pug nose), and mental retardation. The first case had all the metabolic abnormalities of pseudohypoparathyroidism; the second case had urinary cyclic adenosine-3',5'-monophosphate findings suggestive of pseudo-pseudohypoparathyroidism. Therefore acrodysostosis cannot be differentiated from pseudohypoparathyroidism or pseudopseudohypoparathyroidism on clinical and radiologic features only.
