Correct answer: A — Most localised GA resolves spontaneously within 2 years without treatment (approximately 50-75% self-resolve)
Localised granuloma annulare has an excellent prognosis — approximately 50-75% of cases resolve spontaneously within 2 years. For this reason, active treatment is often not necessary, and reassurance is the primary management. Recurrence at the same or different sites occurs in approximately 40% after spontaneous resolution. Active treatment (potent topical/intralesional corticosteroids, cryotherapy) is reserved for symptomatic, cosmetically bothersome, or persistent lesions. Generalised GA is more treatment-resistant and less likely to spontaneously resolve — options include phototherapy, Hydroxychloroquine, Dapsone, and isotretinoin. The diabetes association is debated but screening is reasonable.
