Hi, Welcome to Chat Doctor, Most common cause of itchy eruption or patch under the breast is Tina corporal. It starts as pa pule and soon turns into a patchy lesion with scales and pa pule + vesicles at the periphery. Tab terminating 250 mg daily at night for 15 days will help. Sertaconazole cream to be applied twice daily. Tab Cetirizine 10 mg daily at night. Keep the area clean and Chat Doctor. Thanks
