Psoriasis Responsible Physician Dr. Katerina Kyriakou Dermatologist - Venereologist Psoriasis is a common, chronic, inflammatory skin disease that affects the skin, nails and joints.It is characterized by the presence of erythematous plaques, which are covered by silvery scales, and are found mainly on the elbows, knees and scalp. The most frequent lesions of psoriatic onychiasis are pits, salmon spots and onycholysis. 1/3 of patients with psoriasis develop psoriatic arthritis, which may precede, accompany or follow the skin manifestations of the disease.Psoriasis is a multifactorial disease caused by a combination of genetic, immunological and environmental factors. Stress, smoking, trauma, some infections and certain medications seem to trigger the manifestation of the disease in people with a genetic predisposition.Treatments are divided into local and classic systemic (cyclosporine, methotrexate, acitretin), while in recent years injectable biological treatments have been available in our pharmaceutical arsenal, which have an indication for more serious forms of the disease. Undoubtedly, the treatment of psoriasis is individualized, while the goal of "clear skin" is now achievable, giving patients a very good quality of life.Dermatologist Katerina Kyriakou, trained and specialized in the largest and most well-known Dermatology centers in Greece and abroad, provides comprehensive treatment for the treatment of psoriasis.
