Psoriasis is an autoimmune and inflammatory disease that affects the skin cells and is characterized by the presence of plaques covered with squamous. The aim of this study is to determine the epidemiological, ethiopathogenic and therapeutic profile of a psoriatic population. To this purpose, we conducted a retrospective clinical study on 87 psoriatic patients, the parameters under consideration are: sex, age, socio-economic level, personal and family history, disease history (age and site of beginning, triggering factors and symptoms of beginning, type of psoriasis) and therapeutic strategy. Our results showed that psoriasis affects both sexes equally, as it can appear at any age, although it manifests itself preferentially between 21 and 60 years-old , especially in the following populations: urban (60.90%), smokers (44.8%), those with an autoimmune and/or metabolic pathology (50.5%), family character of psoriasis (9.2%). Similarly, medication (32%), stress (17.2%) and psycho-affective shock (11.4%) are the major triggering factors. This pathology is mainly manifested by pruritus (41.4%), of which (71%) of patients have a vulgar type. The therapeutic strategy was rotational between the different therapeutic weapons with a dominance of partial response (43.7%) to therapies.
