To develop a milestone-based evaluation system for the core "knowledge and skills" competency of neurology residents that is tailored to China's medical context, so as to provide precise guidance for their training and assessment. Using the Delphi method, the study first constructed an initial framework through literature review, on-site investigation and expert-group discussion. Two rounds of expert consultation were then conducted among specialists in neurology education across China. Indicators were screened and optimized according to the mean score, agreement rate and coefficient of variation (CV), ultimately finalizing the system. The expert response rates in both rounds were 100%. The group authority coefficients were 0.97 and 0.98, with Cronbach's α of 0.90 and 0.88, respectively. The mean scores of all indicators ranged from 3.88 to 5.00, agreement rates from 62.50 % to 100 %, and CVs from 0 to 0.21. The finalized framework comprises one first-level indicator, three second-level indicators and 17 third-level indicators. The milestone evaluation system for core competencies in "knowledge and skills" of neurology residents developed in this study is scientific and reasonable, providing a standardized and scientific assessment tool for the standardized training of neurology residents.

An 11-year-old boy presented with erythematous plaques over the bilateral mandibular and mental regions for 2 years, accompanied by cough and dyspnea for more than 2 months. Chest computed tomography angiography revealed marked stenosis of the right pulmonary artery, irregular aortic caliber, and aortic wall thickening. Histopathological examination of the skin lesion, including immunohistochemistry and special stains, confirmed a chronic suppurative inflammation. Whole-exome sequencing was negative. A final diagnosis of granuloma faciale and Takayasu arteritis was established. Combination therapy with systemic tocilizumab, prednisone, and methotrexate, along with topical 0.1% tacrolimus ointment, resulted in a favorable clinical response. This report summarizes the clinical features of a pediatric case of granuloma faciale and Takayasu arteritis and reviews the etiology, diagnostic approach, and current treatment strategies for the disorders, aiming to enhance clinicians' understanding of these conditions.
