Idiopathic multiple nodular panniculitis in a dachshund dog

A 2-year-old intact female dachshund dog was presented with recurrent subcutaneous nodules and fistulations on the neck, back and hip. The patient was diagnosed as a sterile nodular panniculitis based on the cytology, histopathology, and cultures for bacteria and fungus. The fistulas were surgically removed and methylprednisolone was administrated 2 mg/kg twice daily per oral. The lesions were all disappeared, but the relapses were happened when the dosage of the drug was tapered off. The repeated treatments with methylprednisolone or azathioprine were performed, consequently, the patient was controlled with relatively low-dosage methylprednisolone (0.25 mg/kg, every third day).
