  Myotonia chondrodystrophia, which is easier to diagnose than describe, is a rare congenital disorder inherited as an autosomal recessive. Myotonia is accompanied by chondrodystrophia and epiphyseal dysplasia. Affected individuals are presenting with growth retardation, pectus carinatum, sadly appearance of face, blepharophimosis, ear and dental abnormalities, puckered lips, and hypertrophic muscles. Articular contractures especially in elbow are existing and patients had problems in gait. EMG changes are usually used to differentiate it from congenital myotonia. Immune deficiency disorders are not noted and its etiology is still remained unknown. Therapeutic affaires are of less importance.  Case report: we have presented an 8-year old boy referring due to facial deformity.
