Distinct Outcomes in Localized versus Generalized Granuloma Annulare: A Retrospective Cohort Study Highlighting Subtype-Specific Management Implications

This dataset presents clinical data from a retrospective cohort study of 128 patients with histologically confirmed granuloma annulare (GA), diagnosed between 2019 and 2023 at a single Asian center. It compares outcomes between localized (LGA) and generalized (GGA) subtypes. Included data covers demographics, histology, comorbidities, treatments, and follow-up outcomes. Key findings include: • Overall clearance: 89.4% (LGA) vs 16.7% (GGA, P<0.001) • Treated LGA achieved high clearance rates; treated GGA had 0% clearance • Spontaneous resolution: 88.5% (LGA) vs 60.0% (GGA) • Diabetes prevalence: 16.7% (GGA) vs 3.8% (LGA, P=0.038) • Recurrence: 55.6% (GGA) vs 26.9% (LGA) This data supports subtype-specific management and enables reproducible research on GA in an Asian population.
