الملخص EN

Bacground.

Psoriasis is an erythematosquamous dermatosis of chronic development.

In sub-Saharan Africa, few studies have been focused on complicated forms of psoriasis.

Objective.

The aim is to describe epidemiological, clinical, and histological features of severe skin forms of psoriasis in Cote d’Ivoire.

Material and Methods.

The study was both cross-sectional and descriptive, that focused on patient admitted to the dermatology unit for complicated psoriasis, from January 1st, 1986, to December 31th, 2007.

Results.

Fifty-six patients admitted to hospital for severe skin forms of psoriasis were recorded and included in our study over 7.503 patients hospitalized during the study period.

They represented 0.75% of cases.

The average age was 39.6 ± 3.3 years.

There were 49 male (87.5%) and 7 female patients (12.5%) with a sex ratio of 7.

At socioprofessional level, 48 patients (87.5%) were from category 1.

Patients’ history was dominated by the psoriasis vulgaris.

Physical and general signs were dominated by itching (58.9%).

The three severe skin forms were observed with predominant erythrodermic psoriasis (60.7%).

Fifteen patients (34.9%) were HIV positive.

Conclusion.

Severe skin forms of psoriasis are rare in our setting.

But in the quarter of HIV-positive patients, they are dominated by the erythrodermic psoriasis.
