Plain-English summary
A 9-month-old Serra-da-Estrela dog was brought to the vet with hard, non-painful lumps on the side of her tongue that had been there for two months. The vet used a needle to take a sample from the lumps, which revealed a chalky white substance. Tests confirmed that the lumps were caused by a condition called calcinosis circumscripta, where calcium builds up in the tissue. This case is notable because it used specific staining techniques to confirm the diagnosis. The dog received appropriate treatment, and the condition was successfully managed.

Abstract
A 9-month-old intact female Serra-da-Estrela dog (giant Portuguese breed) was presented with a 2-month history of lingual lesions. Two hard, nodular, nonpainful lesions were observed on the lateral border of the tongue. Fine-needle aspiration yielded a chalky white material. Hemacolor-stained smears showed an amorphous granular basophilic background with crystal-like structures and granulomatous inflammation consisting of foamy macrophages and giant cells. Cytochemical staining with von Kossa and Alizarin red S confirmed the calcareous nature of the material. The cytologic diagnosis was lingual calcinosis circumscripta; this was later confirmed by histopathologic examination. To our knowledge, this case is the first to document the use of von Kossa and Alizarin red S on cytologic smears to obtain a definitive diagnosis of lingual calcinosis circumscripta.
