Melnick−Needles Syndrome Associated with Growth Hormone Deficiency: A Case Report

Melnick−Needles syndrome is an X−linked dominant bone dysplasia characterized by a typical facies (exophthalmos, full cheeks, micrognathia, and malalignment of teeth), flaring of the metaphyses of long bones, s−like curvature of the lower extremities, irregular constriction in the ribs, and sclerosis of base of the skull. The phenotype of affected individuals varies, even within families. About fifty cases of Melnick−Needles syndrome have been reported to date. Short stature is not a well−known component of the disorder. There is only one reported case of Melnick−Needles syndrome associated with growth hormone deficiency. A six−year−old girl who presented to our clinic with short stature was diagnosed as Melnick−Needles syndrome based upon characteristic clinical and radiological findings. Two different stimulation tests demonstrated growth hormone deficiency. Presenting this second case of Melnick−Needles syndrome associated with growth hormone deficiency, we suggest that this association may be coincidental, but that it may also be a consequence of craniofacial abnormalities or an independent component of the disorder.
