"Is scleroderma like psoriasis?"


Both of them cause hard skin right? Does scleroderma involve plates like psoriasis does?


Scleroderma and psoriasis are similar in that both are autoimmune diseases in which the skin is affected. However, there are not many similarities beyond this comparison between the two conditions. Psoriasis, in its most common form, causes thickened plaques to build up on the skin, usually on the extensor surfaces of the joints (such as the backs of the elbows and the fronts of the knees).

These plaques may initially be red and may eventually develop a classic silvery-white appearance. While the skin in these plaques is thickened, the rest of the body not affected by the plaques does not become hardened. Psoriasis is often associated with inflammation of joints and tendons, and can also cause changes in the finger- and toenails. Scleroderma, on the other hand, does not typically cause the skin to develop distinctive plaques like those seen in psoriasis. However, scleroderma does cause skin to become hardened and tight, classically affecting the digits and the face. Scleroderma is often associated with color changes in the fingers and toes that occurs with changes in temperature (called Raynaud's Phenomenon). Scleroderma can also affect the body beyond the skin, including damage to the internal organs, blood vessels and muscles. If you have any questions or concerns about scleroderma, psoriasis or any other conditions that may be affecting the skin, you should discuss them further with your primary care doctor.
