The Spectrum and Sequelae of Acne in Black South Africans Seen in Tertiary Institutions

Introduction: Acne is a chronic disorder of the pilosebaceous unit affecting all ethnic groups. It remains in the top 5 skin conditions seen worldwide. The paucity of data characterizing acne in South African Blacks led us to the documentation of types and sequelae of acne. Methods: This is a cross- sectional study describing the spectrum and variants of acne in 5 tertiary hospitals in the second most populous province in South Africa over 3 months (January 1 – March 31, 2015). Results: Out of 3,814 patients seen in tertiary dermatology clinics, 382 (10%) had a primary diagnosis of acne or rosacea, forming the fourth most common condition seen. Acne accounted for 361 (94.5%); acne vulgaris was the commonest subtype at 273 (75.6%), followed by steroid-induced acne 46 (12.7%), middle-age acne 6 (1.7%), acne excoriée 2 (0.6%), and “undefined” 34 (9.4%). Conclusion: The observation of steroid-induced acne as the second most common variant in Black patients underlines the need to enquire about steroid use and education about the complications of using steroid-containing skin-lightening creams. Treatment of postinflammatory hyperpigmentation should be part of the armamentarium for holistic acne treatment in Blacks, as it remains a major concern even after active acne has resolved.
