The authors have demonstrated subcutaneous calcification which is characteristic for pseudo-pseudo-hypoparathyroidism (pph) and which is best shown by xero-radiography. If the presence of pph is suspected, or if it needs to be distinguished from some other condition, it is valuable to obtain xerograms of the soft tissues of the extremities. In pph the subcutaneous calcification is in all probability derived from the skeleton.
作者已经证实了皮下钙化，这是假性假性甲状旁腺功能减退症（pph）的特征，通过干板X线照相术能最好地显示出来。如果怀疑存在pph，或者需要将其与其他疾病区分开来，获取四肢软组织的干板X线照片是很有价值的。在pph中，皮下钙化很可能来源于骨骼。
