Birefringent crystals of calcium oxalate have been previously identified in the colloid of human thyroid glands. We found such crystals in 19/20 adult thyroids at autopsy, in 4/20 infants at autopsy, and, using frozen sections, in 19/20 thyroids partially or totally removed at surgery. These crystals were soluble in hydrochloric acid, insoluble in acetic acid, and contained only calcium by energy dispersive X-ray microanalysis, confirming their calcium oxalate character. Similar crystals were found in equine and ovine thyroids.
草酸钙双折射晶体先前已在人类甲状腺胶体中被鉴定出来。我们在19/20例成人尸检甲状腺中、4/20例婴儿尸检甲状腺中发现了此类晶体，并且通过冰冻切片，在19/20例手术中部分或全部切除的甲状腺中也发现了此类晶体。这些晶体可溶于盐酸，不溶于乙酸，通过能量色散X射线微量分析仅含有钙，证实了它们草酸钙的性质。在马和羊的甲状腺中也发现了类似的晶体。
