ABSTRACT
Background@#The clinical features of inflammatory papulardermatoses of the face are very similar. Their clinical manifestationshave been described on the basis of a small numberof case reports and are not specific. @*Objective@#This studyaimed to use computer-aided image analysis (CAIA) to comparethe clinical features and parameters of inflammatorypapular dermatoses of the face and to develop a formalizeddiagnostic algorithm based on the significant findings. @*Methods@#The study included clinicopathologically confirmedinflammatory papular dermatoses of the face 8 casesof eosinophilic pustular folliculitis (EPF), 13 of granulomatousperiorificial dermatitis-lupus miliaris disseminatusfaciei (GPD-LMDF) complex, 41 of granulomatous rosacea-papulopustular rosacea complex (GR-PPR) complex,and 4 of folliculitis. Clinical features were evaluated, andarea density of papular lesions was quantitatively measuredwith CAIA. Based on these variables, we developed a predictivemodel for differential diagnosis using classificationand regression tree analysis. @*Results@#The EPF group showedlesion asymmetry and annular clusters of papules in all cases.The GPD-LMDF complex group had significantly higher perioculardensity. The GR-PPR complex group showed a higherarea density of unilateral cheek papules and the highest total area density. According to the predictive model, 3 variableswere used for differential diagnosis of the 4 diseasegroups, and each group was diagnosed with a predictedprobability of 67%∼100%. @*Conclusion@#We statisticallyconfirmed the distinct clinical features of inflammatory papulardermatoses of the face and proposed a diagnostic algorithmfor clinical diagnosis.
