Hence solitary ulcers of palate can often be a challenging one to diagnose. We report an interesting case of a diffuse large B cell lymphoma of the maxillary sinus which perforated the palatal bone and presented clinically as a palatal ulcer. Initially the lesion manifested as a small ill-defined swelling in the posterior palatal slope in relation to 24and25 which were mobile and hence was erroneously diagnosed as chronic periodontal abscess. This paper is intended to stress the relevance of including non-Hodgkin\u2019s lymphoma in the differential diagnosis of solitary palatal ulcers as it may be often misdiagnosed as more common reactive or inflammatory lesions.<\/jats:p>","DOI":"10.1136\/bcr-2018-228605","type":"journal-article","created":{"date-parts":[[2019,2,9]],"date-time":"2019-02-09T09:59:17Z","timestamp":1549706357000},"page":"bcr-2018-228605","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Extranodal diffuse large B cell lymphoma of maxillary sinus presenting as a palatal ulcer"],"prefix":"10.1136","volume":"12","author":[{"given":"Mahija","family":"Janardhanan","sequence":"first","affiliation":[{"name":"Department of Oral Pathology and Microbiology, Amrita School of Dentistry,AIMS Campus,Amrita Vishwa Vidyapeetham, Kochi, Kerala, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rakesh","family":"Suresh","sequence":"additional","affiliation":[{"name":"Department of Oral Pathology and Microbiology, Amrita School of Dentistry,AIMS Campus,Amrita Vishwa Vidyapeetham, Kochi, Kerala, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6503-4306","authenticated-orcid":false,"given":"Vindhya","family":"Savithri","sequence":"additional","affiliation":[{"name":"Department of Oral Pathology and Microbiology, Amrita School of Dentistry,AIMS Campus,Amrita Vishwa Vidyapeetham, Kochi, Kerala, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ravi","family":"Veeraraghavan","sequence":"additional","affiliation":[{"name":"Department of Oral Surgery, Amrita School of Dentistry, AIMS Campus, Amrita Vishwa Vidyapeetham, Kochi, Kerala, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,2,9]]},"reference":[{"key":"2025082622551058000_12.2.bcr-2018-228605.1","doi-asserted-by":"crossref","first-page":"391","DOI":"10.1016\/j.ijom.2004.08.009","article-title":"Characteristics of 40 primary extranodal non-hodgkin lymphomas of the oral cavity in perspective of the new who classification and the international prognostic index","volume":"34","author":"van der Waal","year":"2005","journal-title":"Int J Oral Maxillofac Surg"},{"key":"2025082622551058000_12.2.bcr-2018-228605.2","doi-asserted-by":"crossref","first-page":"338","DOI":"10.1016\/j.oooo.2014.06.002","article-title":"Large B-cell lymphoma of the base of the tongue and oral cavity: a practical approach to identifying prognostically important subtypes","volume":"118","author":"Owosho","year":"2014","journal-title":"Oral Surg Oral Med Oral Pathol Oral Radiol"},{"key":"2025082622551058000_12.2.bcr-2018-228605.3","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19900915)66:6<1190::AID-CNCR2820660619>3.0.CO;2-U"},{"key":"2025082622551058000_12.2.bcr-2018-228605.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.critrevonc.2012.12.009"},{"key":"2025082622551058000_12.2.bcr-2018-228605.5","doi-asserted-by":"crossref","first-page":"225","DOI":"10.1016\/0964-1955(93)90027-C","article-title":"Oral presentation of lymphoma: case report of T-cell lymphoma masquerading as oral crohn\u2019s disease, and review of the literature","volume":"29B","author":"Scully","year":"1993","journal-title":"Eur J Cancer B Oral Oncol"},{"key":"2025082622551058000_12.2.bcr-2018-228605.6","unstructured":"Sivapathasundharam B , Satish Muthukumar R , Rajendran R .
