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.
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.
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.
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.
施密德干骺端软骨发育不良是身材矮小的罕见原因,与其他类型的软骨发育不良相比,因其生长板完整性正常,预后良好。
作者报告了一例罕见病例,一名4岁2个月大的男孩因匀称性身材矮小转诊至我院。他有蹒跚步态、轻度短肢畸形和腰椎前凸,无特殊面容。
骨骼扫描诊断为施密德干骺端软骨发育不良。首次实验室检查显示促甲状腺激素和抗组织转谷氨酰胺酶免疫球蛋白A升高。十二指肠活检确诊为乳糜泻。开始使用左甲状腺素治疗并采用无麸质饮食。6年后,他的复查显示胰岛素样生长因子1水平低和生长激素峰值低,确诊为生长激素缺乏症,开始生长激素治疗并调整左甲状腺素剂量。
诊断软骨发育不良时不应遗漏身材矮小的其他原因,应进一步检查以发现其他伴随疾病,因为干骺端软骨发育不良是身材矮小的罕见原因,而甲状腺功能减退和乳糜泻相对常见。
