[Profile of immune and allergic dermatoses among children at the outpatient dermatology clinic in Cotonou (Benin)].

OBJECTIVE

The aim of this work was to study the profile of immune and allergic dermatoses (IAD) in children consulting at the outpatient dermatology clinic at the National University Hospital in Cotonou (Benin).

METHOD: This retrospective descriptive study examined records of children consulting with this diagnosis over a 10-year period.

RESULTS

IAD (902 cases, 37%) were the most common pediatric dermatosis, followed by infectious dermatosis (24%). The sex ratio of children was 0.78. The age groups most strongly affected were those aged 1-30 months (25.39%) and 150-180 months (19.73%). The main IAD were: eczema (47.9%) and prurigo simplex (40.7%). Other IADs included lichen planus (5.1%), toxicoderma (3.8%), urticaria (1.5%), and erythrodermic eczema (1%). The incidence of eczema increased from 13.5% in 2000 to 21.5% in 2009, an increase of 62.2% over 10 years.

CONCLUSION

IADs are common at the Cotonou hospital clinic and are dominated by eczema, the incidence of which has increased significantly over time.
