Among many factors influencing postponed cancer diagnosis, mask-wearing created difficulties in initial diagnosis of head and neck tumours. This report features a patient who had been covering a submandibular tumour under a surgical mask for more than 6 months. He visited his general practitioner due to a significant weight loss, but he neither took his mask off, nor was he asked to do so. When he reported to our emergency room, we noticed a massive ulcerous mass in the right submandibular region. Histological examination confirmed primary squamocellular carcinoma of submandibular salivary gland. During the Covid-19 pandemic, significant clinical observations may be missed if a surgical mask or respirator are not removed during examination with the potential for increased incidence of medical malpractice claims.<\/jats:p>","DOI":"10.1177\/00258172221141252","type":"journal-article","created":{"date-parts":[[2023,1,19]],"date-time":"2023-01-19T02:37:27Z","timestamp":1674095847000},"page":"56-59","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Late diagnosis of a submandibular gland carcinoma in Covid-19 pandemic"],"prefix":"10.1177","volume":"93","author":[{"given":"Svetlana","family":"Valjarevic","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology with Maxillofacial Surgery, Clinical Hospital Center \u201cZemun\u201d, Belgrade, Serbia"},{"name":"University of Belgrade, Faculty of Medicine, Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dejan","family":"Radaljac","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology with Maxillofacial Surgery, Clinical Hospital Center \u201cZemun\u201d, Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milan B","family":"Jovanovic","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology with Maxillofacial Surgery, Clinical Hospital Center \u201cZemun\u201d, Belgrade, Serbia"},{"name":"University of Belgrade, Faculty of Medicine, Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nenad","family":"Miladinovic","sequence":"additional","affiliation":[{"name":"Department of Clinical Pathology, Clinical Hospital Center \u201cZemun\u201d, Belgrade"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,1,18]]},"reference":[{"key":"bibr1-00258172221141252","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-021-07164-y"},{"key":"bibr2-00258172221141252","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejca.2021.05.012"},{"key":"bibr3-00258172221141252","doi-asserted-by":"publisher","DOI":"10.1016\/S2589-7500(20)30293-4"},{"key":"bibr4-00258172221141252","doi-asserted-by":"publisher","DOI":"10.35680\/2372-0247.1604"},{"key":"bibr5-00258172221141252","doi-asserted-by":"publisher","DOI":"10.4323\/rjlm.2021.305"},{"key":"bibr6-00258172221141252","doi-asserted-by":"publisher","DOI":"10.1001\/jamaoto.2020.0488"},{"key":"bibr7-00258172221141252","unstructured":"Health Workforce Department.
