Plain-English summary

Five cats were brought to the vet because of hard lumps in their paws, which made it uncomfortable for them to walk. Tests showed that all the cats had signs of kidney failure, which can lead to abnormal mineral buildup in the body. A closer look at the paw lesions revealed calcinosis, a condition where calcium deposits form in soft tissues. The findings suggest that the paw problems are linked to their kidney issues. Treatment focused on managing the kidney failure, which is crucial for preventing further complications.

Abstract

This retrospective study describes the clinicopathological findings in five cats with soft tissue mineralisation of interdigital spaces and footpads. Paw disease was the reason for veterinary consultation in three out of five cats. All cats had laboratory findings suggestive of renal failure and high solubility product [calciumxphosphorus]. In all cases, cytological examination of paw lesions was suggestive of calcinosis. The results of our study agree with two previous case reports of paw calcification in the cat, suggesting a metastatic pathogenesis and a correlation between paw mineralisation and renal failure.
