Canine bone sporotrichosis: A case report

Abstract

Sporotrichosis, a subcutaneous and zoonotic mycosis, is caused by dimorphic fungus Sporothrix schenckii. The infection occurs after a traumatic skin injury, while handling plant materials or animals. This disease commonly occurs in cats and is rarely reported in dogs. Herein we report a case of bone sporotrichosis in a dog that presented at the Hospital Unit for Pets (HUP) of the Pontifical Catholic University of Paraná (PUCPR). The animal had a 4-month history of lameness in its thoracic limbs. Haematological, radiological, mycological, and histopathological tests were conducted to confirm the diagnosis. The animal was treated for 2 months with a 10 mg kg-1 PO SID dose of itraconazole, but only partial improvement was observed. A 20% supersaturated potassium iodide solution i.e., a 40 mg kg-1 dose every 24 h was then included for regression and healing of the wounds.
