A rare case of SCHMID metaphyseal chondrodysplasia associated with hypothyroidism,growth hormone deficiency and celiac disease: case report.

UNLABELLED: SCHMID metaphyseal chondrodysplasia is a rare cause of short stature with a good prognosis regarding other types of chondrodysplasia in reason of the normal integrity of the growth plate.

CASE PRESENTATION: The authors present a rare case of 4-year-2-month-old boy referred to our Unit for harmonious short stature, he had a waddling gait, subtle micromelia, and hyperlordosis, no special facies.

CLINICAL DISCUSSION: The skeletal scan made the diagnosis of SCHMID metaphyseal chondrodysplasia. The first laboratory workup showed elevated thyroid stimulating hormone and anti-tissue transglutaminase immunoglobulin A. The duodenal biopsies confirmed the diagnosis of coeliac disease. Treatment of levothyroxine was initiated with a gluten-free diet .6 years later, his re-evaluation showed a low insulin-like growth factor 1 and low growth hormone peaks confirming the diagnosis of growth hormone deficiency, Growth hormone therapy was initiated with an adjusted dose of levothyroxine.

CONCLUSION

Other causes of short stature should not be missed when diagnosing chondrodysplasia, and further investigations should be carried out to detect other concomitant disorders since metaphyseal chondrodysplasia is a rare cause for short stature while hypothyroidism and coeliac disease are relatively common.
