A seven month-old, female English Pointer presented with erythematous alopecia on the left forehead. The lesion had not improved with oral antibiotics, topical antifungal drug, topical ivermectin and oral prednisolone for 2 months. Then skin biopsy was performed, and the lesion was diagnosed as idiopathic sterile granuloma and pyogranuloma. Interestingly, the lesion showed spontaneous regression at 10 days after the biospy, and no relapse has occurred for 1 year.
