In other cases, biopsy remains necessary to establish a histopathological diagnosis and treatment regimen. It is, therefore, essential that OCT assessors have a high specificity for differentiating BCC from non\u2010BCC lesions. To establish high\u2010confidence BCC diagnoses, specific morphological BCC characteristics on OCT are used. This study aimed to review several cases of non\u2010BCC lesions that were misclassified as BCC by experienced OCT assessors, thereby providing insight into the causes of these misclassifications and how they may be prevented. The study population consisted of patients who had a histopathologically\u2010verified non\u2010BCC lesion. Patients from Maastricht University Medical Center+ from February 2021 to April 2021 were included in the study. Two independent OCT assessors assessed OCT scans. One OCT assessor recorded the presence or absence of validated morphological BCC characteristics. A false\u2010positive OCT test result was defined as certainty of BCC presence in a non\u2010BCC lesion. The frequency of misclassifications and the presence or absence of morphological BCC features are discussed. A total of 124 patients with non\u2010BCC lesions were included. Six patients were misclassified by both OCT assessors and are discussed in more detail. Histopathological diagnoses were squamous cell carcinoma (<jats:italic>n<\/jats:italic>\u2009=\u20092\/21), actinic keratosis (<jats:italic>n<\/jats:italic>\u2009=\u20092\/29), squamous cell carcinoma in\u00a0situ\/Bowen's disease (<jats:italic>n<\/jats:italic>\u2009=\u20091\/16), or interphase dermatitis (<jats:italic>n<\/jats:italic>\u2009=\u20091\/4). In all misclassified cases, multiple, apparent morphological BCC characteristics on OCT were present. Most non\u2010BCC lesions are recognized as such by OCT assessors. However, there remains a small risk that a high\u2010confidence BCC diagnosis is established in non\u2010BCC lesions wherein features mimicking validated BCC characteristics are present. Misclassification may be prevented by careful delineation of epidermal layers and good differentiation between dermal ovoid structures typical of BCC versus squamous cell carcinoma.<\/jats:p>","DOI":"10.1111\/1346-8138.17020","type":"journal-article","created":{"date-parts":[[2023,11,6]],"date-time":"2023-11-06T09:10:25Z","timestamp":1699261825000},"page":"40-47","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["\u2018Pitfalls for differentiating basal cell carcinoma from non\u2010basal cell carcinoma on optical coherence tomography: A clinical series\u2019"],"prefix":"10.1111","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0253-8969","authenticated-orcid":false,"given":"Tom","family":"Wolswijk","sequence":"first","affiliation":[{"name":"Department of Dermatology Maastricht University Medical Center+  Maastricht The Netherlands"},{"name":"GROW Research Institute for Oncology and Reproduction Maastricht University  Maastricht The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patty J.","family":"Nelemans","sequence":"additional","affiliation":[{"name":"Department of Epidemiology Maastricht University  Maastricht The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fieke","family":"Adan","sequence":"additional","affiliation":[{"name":"Department of Dermatology Maastricht University Medical Center+  Maastricht The Netherlands"},{"name":"GROW Research Institute for Oncology and Reproduction Maastricht University  Maastricht The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myrurgia","family":"Abdul\u00a0Hamid","sequence":"additional","affiliation":[{"name":"Department of Pathology Maastricht University Medical Center+  Maastricht The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Klara","family":"Mosterd","sequence":"additional","affiliation":[{"name":"Department of Dermatology Maastricht University Medical Center+  Maastricht The Netherlands"},{"name":"GROW Research Institute for Oncology and Reproduction Maastricht University  Maastricht The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,11,6]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2017.10.006"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/srt.12949"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jid.2020.01.034"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(22)00347-3"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00403-014-1498-y"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.17969"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.2340\/actadv.v101.421"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0895-4356(03)00177-X"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2022.10.006"},{"key":"e_1_2_9_11_1","unstructured":"Adam MeekingsGM.Michelson Diagnostics.
