Autoimmune progesterone dermatitis: Introduction. Autoimmune progesterone dermatitis: A skin rash that appears to be a result of the body's immune reaction to progesterone. As progesterone production is linked to menstrual cycles, the rash occurs usually in the week before menstruation until a few days after menstruation starts.
Conditions like this are called autoimmune diseases. Your white blood cells, which normally protect you from germs, attack the glands that are in charge of making moisture. When that happens, they can't produce tears and saliva. Dry eyes and dry mouth are the most common symptoms. You can sometimes get problems in other parts of your body, such as swollen glands around your face and neck, dry skin or nasal passages, or painful and stiff joints.
