The extra skin cells form raised, red, scaly patches that are itchy and sometimes painful. ³ People with psoriasis are also reported to be at increased risk of developing other serious clinical conditions such as cardiovascular and other noncommunicable diseases and to suffer substantial impairment of physical and psychological quality of life. ⁴ Plaque psoriasis is the most common type of psoriasis. ⁵

About Onychomycosis
Onychomycosis is a common condition, caused predominantly by various fungal organisms (fungi), and typically occurs under the toenail, though fingernails may also be affected.
