Calcinosis cutis associated with leptospirosis in a 4‐month‐old dog

Abstract

AbstractCanine leptospirosis is a multisystemic disease that can affect dogs of all ages and lifestyles. This report describes a 4‐month‐old dog diagnosed with acute leptospirosis and treated with dialysis and antibiotic therapy as well as intensive supportive care for 11 days of hospitalisation. About 10 days after discharge, the dog developed cutaneous lesions that were consistent with calcinosis cutis on histopathology. The lesions resolved within 1 month without specific intervention. This report discusses a potential association between calcinosis cutis and leptospirosis infection and highlights a need for early vaccination to protect young dogs.
