Previous Next 4 of 8 Nail psoriasis

Psoriasis can affect fingernails and toenails, causing pitting, abnormal nail growth and discoloration. Psoriatic nails may become loose and separate from the nail bed (onycholysis). Severe cases may cause the nail to crumble.

Nail psoriasis often accompanies another type of psoriasis, such as plaque psoriasis. Treatment options include oral or injected medications.
