Experts’ agreement was rated using a Likert scale (1–7).Results: A consensus was reached on 24 out 34 statements (73.5%) and on 5 out of 8 (62.5%) close-ended questions. The response rate was identical in both rounds (attrition of 0%). AC is the term with the highest agreement (median of 7 (strongly agree; IQR: 6–7)) and the lowest dispersion (VC = 21.33). ‘Potentially malignant disorder’ was the preferred classification group for AC (median of 7) and 85.6% of participants showing some level of agreement (CV < 50). Experts (66.75%) consider AC a clinical term (median: 7; IQR: 4–7) and believe definitive diagnosis can be made clinically (median: 6; IQR: 5–7), particularly by inspection and palpation (median: 5; IQR: 4–6). Histopathological confirmation is mandatory for the management of AC (median: 5; IQR: 2.5–7), even for homogeneous lesions (median: 5; IQR: 3.5–6). Consensus was reached on all treatment statements (VC < 50).Conclusions: AC is a potentially malignant disorder with a significant lack of agreement on diagnostic criteria, procedures, biopsy indications and the importance of techniques to assist in biopsy. A consensus was reached on nomenclature and management of this disorder PB Wiley YR 2021 FD 2021 LK http://hdl.handle.net/10347/26451 UL http://hdl.handle.net/10347/26451 LA eng NO Seoane, J, Warnakulasuriya, S, Bagán, JV, et al.
