Histological findings showed nodular to diffuse dermal infiltration of lymphocytes with irregular nuclei, eosinophils, plasma cells, and mast cells. CD20 revealed patch positivity. Periphery of lymphoid follicles showed BCL-2 positivity and BCL-6 positivity focally at the center. CD30 and toluidine blue staining showed positivity, and several mast cells were confirmed. The immunoglobulin heavy chain gene rearrangement result showed B-cell monoclonality. The patient\u2019s condition was diagnosed as cutaneous marginal zone B-cell lymphoma, plasmacytoid type with mastocytosis. Primary cutaneous marginal zone B-cell lymphoma is an indolent lymphoma with a tendency for local recurrence. In the specimen obtained from our patient, multiple mast cells were observed. Primary cutaneous marginal zone B-cell lymphoma with prominent mastocytosis is rare and there are a few reported cases. Therefore, this case is worth reporting for its rarity and for the purpose of reminding mastocytosis in primary cutaneous marginal zone B-cell lymphoma. <\/jats:p>","DOI":"10.1177\/2050313x211042527","type":"journal-article","created":{"date-parts":[[2021,8,28]],"date-time":"2021-08-28T12:27:34Z","timestamp":1630153654000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["A case report of primary cutaneous marginal zone B-cell lymphoma with mastocytosis"],"prefix":"10.1177","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7230-1089","authenticated-orcid":false,"given":"Hyun Yi","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Dermatology, Eulji University Hospital, Eulji University School of Medicine, Daejeon, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joong Sun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Eulji University Hospital, Eulji University School of Medicine, Daejeon, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dae Won","family":"Koo","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Eulji University Hospital, Eulji University School of Medicine, Daejeon, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,8,28]]},"reference":[{"key":"bibr1-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1590\/abd1806-4841.20153638"},{"key":"bibr2-2050313X211042527","volume":"125","author":"Cho-Vega JH","year":"2006","journal-title":"Am J Clin Pathol"},{"key":"bibr3-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.12659\/AJCR.923354"},{"volume-title":"Urticaria Pigmentosa","year":"2021","author":"Macri A","key":"bibr4-2050313X211042527"},{"key":"bibr5-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1016\/j.iac.2013.09.001"},{"key":"bibr6-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e3181f72835"},{"key":"bibr7-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/aqaa116"},{"key":"bibr8-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200009000-00012"},{"key":"bibr9-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1309\/AJCP63OGXHXCSKSC"},{"key":"bibr10-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2012-03-415638"},{"key":"bibr11-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1053\/j.semdp.2016.11.007"},{"key":"bibr12-2050313X211042527","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdl109"}],"container-title":["SAGE Open Medical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X211042527","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2050313X211042527","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X211042527","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,4]],"date-time":"2025-03-04T00:37:40Z","timestamp":1741048660000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2050313X211042527"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,1]]},"references-count":12,"alternative-id":["10.1177\/2050313X211042527"],"URL":"https:\/\/doi.org\/10.1177\/2050313x211042527","relation":{},"ISSN":["2050-313X","2050-313X"],"issn-type":[{"type":"print","value":"2050-313X"},{"type":"electronic","value":"2050-313X"}],"subject":[],"published":{"date-parts":[[2021,1]]},"article-number":"2050313X211042527"}}
