Addison’s Disease is characterized by a darkening of the skin, blotchiness or seemingly “tanned” areas. Unlike some of the other skin conditions on this list, Addison’s Disease is potentially fatal if not caught in time. The symptoms apparent in the patient’s skin can occur along with chronic fatigue, dizziness, nausea, low blood sugar and low blood pressure.
In the case of this disease, skin changes may occur rapidly at a time of high stress that can lead to shock, fainting, and kidney failure. Sudden changes, such as blotchiness, tan skin, or a general darkening of skin pigmentation may be a result of the body’s inability to make hormones like cortisol that regulate adrenal functioning.

Eczema is a chronic skin condition that causes excessive inflammation, dryness, scaling, patchiness, and even bleeding. Fairly common, eczema can be treated with adequate moisturization along with topical steroids. Unfortunately, the severity of the condition varies from person to person, with many sufferers of eczema experiencing the condition based on a combination of genetic and environmental factors.
Photodermatitis, typically known as “sun poisoning”, often occurs when a warm, humid climate causes the immune system to react to UV light. The skin erupts in rash, blisters and hyperpigmentation, and may be additionally accompanied by fever and the chills.
