Psoriasis is a chronic skin condition with several types:
Plaque Psoriasis, marked by red patches with silvery scales;
Guttate Psoriasis, characterized by small, drop-shaped spots;
Pustular Psoriasis, featuring red skin with pus-filled blisters;
Inverse Psoriasis, which affects moist skin folds; and
Erythrodermic Psoriasis, a severe, emergency condition with widespread redness and peeling. It is
not contagious. The causes include
immune system dysregulation, where T-cells attack healthy skin cells, and
genetic factors. Common triggers include
alcohol, certain
medications, and
infections. Diagnosis is through a
physical exam and sometimes a
biopsy. Though incurable, treatments can manage symptoms and improve quality of life.
