I have a 7 year old gelding paint diagnosed with eosinophilic balanitis. Lesions were first noticed in cool weather, before fly season. They grew in size very rapidly. Lab couldn't find any organism in biopsy. He is currently on oral ivermectin every 10 days for 3 weeks, topical ivermectin, steroid cream 4 times a week, and oral antibiotic. Dr O do you have anymore info about this?

The term eosinophilic balanitis is not a diagnosis but a histological description that could be due to several causes. The term means inflammation of the glans penis with eosinophils. Often these lesions are tumorous. A common cause for eosinophilic tumors is the fly larva Habronema which is why they are using ivermectin. Other possibilities would include: collagenolytic granuloma, amyloidosis, and mast cell tumors. Sometimes lymphosarcoma can cause a cutaneous eosinophilic dermatitis but I don't think it presents as discreet tumors. These diseases often present with a strong eosinophilic infiltrate. Perhaps total removal of one of the masses would allow for a complete examination for the primary disease.
