Аннотация
BACKGROUND: Deposition of calcium salts in the skin and subcutis, referred to as calcinosis cutis, is a common complication in patients with end-stage renal disease. The lesion can present as a mass and is amenable to fine needle aspiration (FNA).
CASE: A 48-year-old man undergoing hemodialysis following a failed renal transplant presented with a 1.5-cm neck nodule. A diagnosis of calcinosis cutis was made following FNA, which obtained semiliquid, chalky material.
CONCLUSION: In cytologic preparations, deposits of calcium salts can be both amorphous and refractile on Diff-Quik and Papanicolaou stain. However, the material may not be birefringent with these stains. Alizarin red S stain for calcium will permit demonstration of the characteristic birefringence.
