Here you will find skin conditions that affect the back in adults. Several conditions are prone to affect the back. Tinea versicolor is an example of a fungal infection that will often cause color changes in the skin on the back. Additionally, certain rashes have an affinity for the skin in this area. For example, pityriasis rosea will typically cause pink patches over the entire back. Solar lentigos (sun spots) are the result of accumulated sun exposure. These spots are not cancerous, but they are indicators of higher risk for the development of skin cancers, so these spots should be evaluated by your doctor regularly to screen for possible skin cancer hidden among them. Notalgia paresthetica is thought to be the result of changes in the nerves of the skin and can cause itching in the skin of the back. Areas of notalgia paresthetica will often darken in time.
