It has features similar to other granulomatous and infectious diseases of the nose and paranasal sinuses, which can make diagnosis challenging and delayed. We present a case of 38-year-old man who was admitted to the hospital on three occasions over a 3-month period for right periorbital erythema, nasal congestion and discharge. Following two separate surgical debridement and biopsies, ENKTCL was diagnosed and the patient was commenced on chemoradiotherapy. The case highlights the atypical nature of his presentation and the high degree of suspicion for a pathological process that must be maintained to formulate the diagnosis.<\/jats:p>","DOI":"10.1136\/bcr-2020-238113","type":"journal-article","created":{"date-parts":[[2021,4,1]],"date-time":"2021-04-01T13:21:35Z","timestamp":1617283295000},"page":"e238113","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Nasal-type extranodal NK\/T-cell lymphoma presenting as recurrent periorbital cellulitis"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4780-4124","authenticated-orcid":false,"given":"Mansoor Ali","family":"Hussein","sequence":"first","affiliation":[{"name":"otolaryngology, Tallaght Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seamus","family":"Boyle","sequence":"additional","affiliation":[{"name":"Otolaryngology, Tallaght University Hospital, Dublin, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shawkat","family":"Abdulrahman","sequence":"additional","affiliation":[{"name":"Otolaryngology, Tallaght Hospital, Dublin, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brendan","family":"Fennessy","sequence":"additional","affiliation":[{"name":"Otolaryngology, Tallaght University Hospital, Dublin, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,4,1]]},"reference":[{"key":"2025082804321452000_14.4.e238113.1","doi-asserted-by":"publisher","DOI":"10.1007\/s11899-016-0355-9"},{"key":"2025082804321452000_14.4.e238113.2","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1016\/j.anl.2003.07.005","article-title":"Successful treatment of disseminated nasal T-cell lymphoma using high-dose chemotherapy and autologus peripheral blood stem cell transplantation: a case report","volume":"31","author":"Kouzaki","year":"2004","journal-title":"Auris Nasus Larynx"},{"key":"2025082804321452000_14.4.e238113.3","doi-asserted-by":"crossref","first-page":"99","DOI":"10.4103\/0975-5950.168217","article-title":"NHL - Extranodal T-cell lymphoma","volume":"6","author":"Devi","year":"2015","journal-title":"Natl J Maxillofac Surg"},{"key":"2025082804321452000_14.4.e238113.4","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1186\/s13045-017-0452-9","article-title":"The diagnosis and management of NK\/T-cell lymphomas","volume":"10","author":"Tse","year":"2017","journal-title":"J Hematol Oncol"},{"key":"2025082804321452000_14.4.e238113.5","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2017-221019","article-title":"Late diagnosis: a case of rapidly progressive extranodal NK\/T cell lymphoma, nasal type","volume":"7","author":"Mori","year":"2018","journal-title":"BMJ Case Rep"},{"key":"2025082804321452000_14.4.e238113.6","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2019-232404","article-title":"Extranodal natural killer\/T cell lymphoma, nasal type: a diagnostic challenge","volume":"12","author":"Gomes","year":"2019","journal-title":"BMJ Case Rep"},{"key":"2025082804321452000_14.4.e238113.7","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2011-05-354142"},{"key":"2025082804321452000_14.4.e238113.8","article-title":"Extranodal natural killer\/T cell lymphoma, nasal type presenting as a palatal perforation and naso-oral fistula","volume":"2011","author":"Bhatt","year":"2011","journal-title":"Case Reports"},{"key":"2025082804321452000_14.4.e238113.9","doi-asserted-by":"publisher","DOI":"10.3109\/10428194.2010.544049"},{"key":"2025082804321452000_14.4.e238113.10","doi-asserted-by":"crossref","unstructured":"Hughes E , Fogarty H , Fortune A , et al .
