[Presenting skin disorders in black Afro-Caribbean patients: a multicentre study conducted in the Paris region].

Background: There have been few studies in France concerning the specific features of dermatological practice regarding dark skin (Fitzpatrick's phototype V and VI) or the special requirements of black African and Afro-Caribbean patients.

Aim: To determine the principal reasons for dermatological consultation among black patients of African or Afro-Caribbean descent in the Paris region.

Methods: This was a prospective clinical study conducted between 15 February and 15 May 2004. The diagnoses of cutaneous conditions leading to dermatological consultation for all black patients of phototype V to VI were recorded by 10 dermatologists practicing in 14 centres within the Paris region.

Limits: The method used did not allow any conclusions to be drawn regarding the incidence of the presenting conditions among the global population nor did it allow comparison between populations of different phototypes. The absence of any preset list of diagnoses or of precise inclusion criteria regarding evaluation of skin colour left individual investigators with a broad margin of interpretation.

Results: In 836 adults and 228 children (half of whom were from Africa and half from the West Indies), diagnoses were as follows: acne in 29.2% of adults and 13.2% in children, and eczema in 6.8% of adults and 27.2% of children. Among dermatoses more specific to black subjects, scalp conditions were frequently seen in both adults (alopecia 7% of diagnoses) and children (tinea capitis 9.6% and alopecia 3.6% of diagnoses). In at least 25% of cases, consultation was associated with dyschromia. Clinical signs suggesting the use of skin lightening products were seen in 95 patients.

Conclusion: In France, as in other industrialized countries, black patients consult dermatologists essentially for common benign dermatoses also seen amongst white people. Nevertheless, it is important to emphasise the presence of skin problems specific to black patients such as dyschromia and pigmentary disorders, hair and scalp dermatoses, and side effects associated with the use of skin lightening products.
