Histopathologic findings include epithelioid and multinucleated histiocytes with ground glass cytoplasm. We demonstrate the case of a 52\u2010year\u2010old female who presented with scattered red\u2010brown papules, finger swelling, and muscle pain. Biopsy demonstrated a dermal proliferation of large mononucleated and multinucleated histiocytes with dense, pink, oncocytic cytoplasm, consistent with MRH. Patient initiated prednisone, methotrexate, folic acid, and adalimumab. On follow\u2010up, the patient reported progressive hair loss confined to the frontal scalp. Physical exam showed moderately well\u2010defined, pauci\u2010inflammatory alopecic patches with follicular drop\u2010out and negative hair pull test. A punch biopsy from the scalp demonstrated a marked decrease in follicular units associated with aggregates of histiocytes in the upper dermis with infiltration of the follicular epithelium, some multinucleate, with abundant two\u2010toned ground\u2010glass cytoplasm. A diagnosis of alopecia secondary to follicular involvement by reticulohistiocytosis was made. To our knowledge, this is the first reported case of alopecia secondary to MRH in the literature.<\/jats:p>","DOI":"10.1111\/cup.70107","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:34:37Z","timestamp":1777458877000},"page":"898-900","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Multicentric Reticulohistiocytosis Induced Alopecia: A Clinical Case Report"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-1450-9161","authenticated-orcid":false,"given":"Hayley","family":"Zimbric","sequence":"first","affiliation":[{"name":"College of Medicine The Ohio State University  Columbus Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5562-6153","authenticated-orcid":false,"given":"Gabrielle","family":"Brokamp","sequence":"additional","affiliation":[{"name":"Department of Dermatology The Ohio State University  Gahanna Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4158-9136","authenticated-orcid":false,"given":"Catherine G.","family":"Chung","sequence":"additional","affiliation":[{"name":"Department of Dermatology The Ohio State University  Gahanna Ohio USA"},{"name":"Department of Pathology The Ohio State University  Columbus Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6924-6736","authenticated-orcid":false,"given":"Jessica","family":"Kaffenberger","sequence":"additional","affiliation":[{"name":"College of Medicine The Ohio State University  Columbus Ohio USA"},{"name":"Department of Dermatology The Ohio State University  Gahanna Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12016-013-8362-2"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.berh.2016.07.002"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11926-015-0511-6"}],"container-title":["Journal of Cutaneous Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cup.70107","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/cup.70107","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cup.70107","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T15:12:01Z","timestamp":1788275521000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/cup.70107"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,29]]},"references-count":3,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2026,10]]}},"alternative-id":["10.1111\/cup.70107"],"URL":"https:\/\/doi.org\/10.1111\/cup.70107","archive":["Portico"],"relation":{},"ISSN":["0303-6987","1600-0560"],"issn-type":[{"value":"0303-6987","type":"print"},{"value":"1600-0560","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,29]]},"assertion":[{"value":"2025-09-08","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-03-23","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-04-29","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
