Oral abrocitinib in the treatment of granuloma annulare: a case report.

Aim: To evaluate the therapeutic efficacy and safety of JAK inhibitor abrocitinib in patients with localized granuloma annulare (GA) and to review the available cases documented in English. Methods: We presented a patient who had a persistent, localized granuloma anulare (GA) for one year and did not respond to traditional therapies. This patient was treated with oral abrocitinib at a dosage of 150 mg daily. Results: After 6 weeks of treatment with abrocitinib, the patient exhibited notable symptom improvement with no new lesions. No adverse events or recurrences were reported during the 5-month follow-up period. Conclusions: Abrocitinib may be a promising and safe treatment option for patients with localized GA who do not respond to traditional therapies.
