Preheat the oven to 350 degrees F. Mix together the cream cheese, hot sauce and sour cream in a large bowl until well combined. Fold in the turkey. Transfer the mixture to a 2-quart casserole dish.
Bake until hot and bubbly, about 20 minutes. Sprinkle with the blue cheese and scallions. Serve with celery and carrot sticks, crackers and bread for dipping.
