title: Unusual features of rosacea in saudi females with dark skin.
abstract: BACKGROUND
  Data on the clinical presentation of rosacea among darker-skinned ethnic groups is scarce. This article presents the clinical spectrum of rosacea in Saudi female patients with differences highlighted according to skin types.
  
  
  METHODS
  Female patients diagnosed with rosacea at the dermatology clinic in King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia, between February 2010 and May 2011 were studied prospectively. Data collected included demographics, duration of the disease, personal history of any atopic disorder, aggravating factors, cutaneous and ocular symptoms, the presence of migraine, Helicobacter pylori infection, skin phototypes, and the clinical types and severity of rosacea.
  
  
  RESULTS
  FIFTY PATIENTS CONSENTED TO JOIN THE STUDY: 20 (40%) were patients with skin type 4, 9 (18%) had skin type 5, and 21 (42%) had skin type 6. The cheeks, glabella, and chin were involved in 26 (52%) patients. Extrafacial lesions affecting chest, back, and ears were identified in 7 patients (14%). Severe erythematotelangiectatic rosacea was diagnosed in 21 patients (42%): skin type 4 comprised 50%, higher than the incidences for skin type 5 (22%) and skin type 6 (42.9%). The severe papulopustular subtype of rosacea was noted in 7 patients (14.0%), affecting 20% with skin type 4 and 14% with skin type 6. Severity of the erythematotelangiectatic or papulopustular subtypes of rosacea was not significantly associated with skin type (P=0.5691 and P=0.7740, respectively).
  
  
  CONCLUSIONS
  This study addresses the growing interest in skin diseases in dark-skinned individuals. Rosacea is one of the skin disorders that had always been described for fair-skinned populations, but our results indicate that darker-skinned individuals also can be affected by rosacea and the clinical presentation is similar to that seen in patients with fair skin.
