A new case of Melnick-Needles syndrome with skeletal manifestations: A case report.

INTRODUCTION AND IMPORTANCE

Melnick-Needles syndrome (MNS) is a rare skeletal dysplasia that affects skeletal and connective tissue. Less than 70 cases of MNS reported in the literature. MNS had various clinical manifestations such as skeletal deformity, cortical bony sclerosis, facial abnormality, and urogenital symptoms.

CASE PRESENTATION

We presented a 5-year-old girl who referred to our orthopedic clinic with knee valgus deformity, spinal kyphoscoliosis, bilateral coxa valga, and humerus cortical irregularity. Based on some facial and skeletal feature, MNS was confirmed with genetic evaluation (heterozygote Filamin A genome).

CLINICAL DISCUSSION

The diagnosis of MNS requires a thorough medical and family history, physical examination, and radiographic evaluation. Differential diagnoses for patients with skeletal and facial deformities like MNS include Camurati-Engelmann disease, cystinuria, Galloway-Mowat syndrome, Joubert syndrome, and mucopolysaccharidosis. Treatment for MNS patients with bony deformities without lethal conditions can be conservative, but corrective surgery may be necessary in some cases.

CONCLUSIONS

MNS was a rare syndrome with common clinical manifestations such as limb and spine deformity. It is important to conduct a careful examination of any patient who presents with limb and skeletal deformity to the orthopedic clinic, as the disease may have some lethal clinical implications.
