10 Causes of Geographic Tongue
Cause #4: Psoriasis
Psoriasis is a chronic autoimmune condition where there are patches of abnormal skin. The patches are usually scaly, red, itchy, and dry. The severity varies ranging from small and localized patches to complete involvement of the body. Psoriasis can be divided into 5 types: guttate, plaque, pustular, erythrodermic, and inverse. Psoriasis can also affect the fingernails and toenails.
Psoriasis is not a contagious condition and it can be treated with vitamin D3 cream, steroid creams, immune system suppressing medications, and ultraviolet light. Psoriasis has been associated with increased likelihood of other conditions such as cardiovascular disease, psoriatic arthritis, lymphomas, and geographic tongue.
