Calcinosis cutis is characterized by the deposition of calcium salts in the subcutaneous tissues of the body. Metastatic calcifications can occur in the body in hyperparathyroidism and end-stage renal disease. Calcifications can also occur in a variety of other clinical settings and can be subjected to fine-needle aspiration (FNA). Calcinosis cutis was diagnosed by FNA in a 20-yr-old male who presented with a solitary subcutaneous nodule near the ankle, on the lateral malleolus. Smears showed amorphous granular material consistent with calcium, and occasional histiocytes. The presence of amorphous calcium salts along with histiocytes in the appropriate clinical setting is diagnostic of calcinosis cutis. The diagnosis was confirmed on histology. Diagn.

皮肤钙质沉着症的特征是身体皮下组织中钙盐沉积。转移性钙化可发生于甲状旁腺功能亢进和终末期肾病患者体内。钙化也可发生于多种其他临床情况，且可进行细针穿刺抽吸（FNA）检查。一名20岁男性因踝关节外侧踝部附近出现一个孤立性皮下结节就诊，通过FNA诊断为皮肤钙质沉着症。涂片显示有与钙相符的无定形颗粒物质以及偶尔可见的组织细胞。在适当的临床情况下，无定形钙盐与组织细胞同时存在可诊断为皮肤钙质沉着症。组织学检查确诊。《诊断性细胞病理学》1999年；21卷：200 - 202页。
