Acrodysostosis — a rare congenital malformation syndrome — is described in a 41/2 year old boy with peripheral dysostosis, nasal hypoplasia, mental retardation (PNM syndrome) and impaired hearing. The differential diagnosis includes pseudo (PH) — and pseudo-pseudohypoparathyroidism (PPH). The patient described here had severe peripheral dysostosis, typical of PNM as opposed to the above-mentioned conditions with only moderate peripheral dysostosis. Furthermore, there were no soft tissue calcifications and no intracranial calcification as can be seen in PH and PPH. Laboratory findings were normal.
