A Study Of Skin Disease Spectrum Occurring In Angola Phototype V-Vi Population In Luanda

BackgroundPrevalence of skin diseases in Luanda (Angola) is unknown, and publications are barely found in the literature. We aim to describe, for the first time, the frequency of skin disease spectrum in phototype V-VI Angolan population in Luanda City.MethodsWe included Fitzpatrick phototype V-VI Angolan patients who consulted the Dermatology Unit in Luanda Medical Center during a 1-year period. Medical information was recovered from the electronic database, and diagnoses were based on ICD-10. Only the main complaint was registered, and the results were classified according to age and sex. Criteria exclusion consisted of incomplete clinical records, Fitzpatrick phototype I-IV Angolan, or foreign patients from the study.ResultsFrom a total of 3938 patients, 3554 met the inclusion criteria, of which 2742 were adults 13 years or older. In this group, acne (23.6%), dermatophytosis (11.0%), and pityriasis versicolor (8.6%) were the main complaints. On the other hand, in the pediatric population (n = 812), atopic dermatitis (29.4%), tinea capitis (13.7%), and molluscum contagiosum (12.5%) were the most frequent disorders. In adult females, acne (31.3%) was the main condition, while in adult males, dermatophytosis (13.5%). In children, the frequency of atopic dermatitis was comparable: 29.1% and 28.6% in girls and boys, respectively.ConclusionsWe published for the first time the frequency of the skin disease spectrum in Fitzpatrick phototype V-VI Angolan population in Luanda City, highlighting the prevalence of acne, dermatophytosis, and atopic dermatitis.
