Guttate Psoriasis 點滴狀牛皮癬
Guttate psoriasis is a type of psoriasis that looks like small, salmon-pink drops on the skin. The word guttate is derived from the Latin word gutta, meaning drop. Usually there is a fine scale on the droplike lesion that is much finer than the scales in plaque psoriasis, the most common type of psoriasis. The trigger to the disease is often a preceding streptococcal (bacterial) infection. The eruption of the lesions on the skin usually happens about two to three weeks after the person has strep throat. The outbreak can go away and not reoccur.

Can Psoriasis Affect Only My Nails?只有發生在指甲的牛皮癬
Yes, psoriasis may involve solely the nails. More commonly, the nail symptoms accompany the skin and arthritis symptoms. Nails affected by psoriasis can have small pinpoint pits or large yellowish separations of the nail plate called "oil spots." Nail psoriasis is typically very difficult to treat, but it can respond to medications taken internally to treat psoriasis or psoriatic arthritis. Treatment options include potent topical steroids applied at the nail-base cuticle, injection of steroids at the nail-base cuticle, and oral or systemic medications as described below for the treatment of psoriasis.
