A case of SCMM metastasis on the mediastinal lymph node is presented in this study. A 54-year-old male patient had a lesion on the palmar side of the right hand and mediastinal lymph node metastasis. Fine needle aspiration biopsies were performed from the lymph nodes. Cytologically, cellular smears consisted of isolated discohesive cells, nuclear aggregates, small layers of cells, and pseudo-rosettes. Two kinds of cells were observed: one with small, round-oval cells, and the other with small to medium cells. Immunohistochemically, tumor cells were positive with S-100, SRY-related HMG-box gene 10, MelanA, and human melanoma black 45. Friend leukemia virus integration 1 was positive in over 10% of tumor cells. Metastatic malignant melanoma may present with different cytomorphologic features. SCMM is a tumor to be aware of because it can be confused with other small round blue cells and misdiagnosed.<\/jats:p>","DOI":"10.4103\/joc.joc_64_24","type":"journal-article","created":{"date-parts":[[2025,8,29]],"date-time":"2025-08-29T17:01:09Z","timestamp":1756486869000},"page":"175-177","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["A Rare Melanoma Variant: Small Cell Malignant Melanoma Metastasis in the Lymph Node"],"prefix":"10.4103","volume":"42","author":[{"given":"Egemen","family":"Akincioglu","sequence":"first","affiliation":[{"name":"Department of Pathology, University of Health Science, Gulhane Training and Research Hospital, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tolga","family":"Baglan","sequence":"additional","affiliation":[{"name":"Department of Pathology, Ankara Etlik City Hospital, Ankara, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,8,29]]},"reference":[{"key":"CIT0001-20250902","doi-asserted-by":"crossref","first-page":"231","DOI":"10.1159\/000503703","article-title":"Small cell variant of metastatic melanoma: A mimicker of lymphoblastic leukemia\/lymphoma","volume":"6","author":"Ronen","year":"2019","journal-title":"Dermatopathology"},{"key":"CIT0002-20250902","first-page":"5319","article-title":"Small cell malignant melanoma of the anus: A case report with review of the literature","volume":"7","author":"Ishida","year":"2014","journal-title":"Int J Clin Exp Pathol"},{"key":"CIT0003-20250902","doi-asserted-by":"crossref","first-page":"619","DOI":"10.1002\/dc.21633","article-title":"Small cell variant of malignant melanoma masquerading as lymphoma on fine-needle aspiration cytology: A case report","volume":"40","author":"Buehler","year":"2012","journal-title":"Diagn Cytopathol"},{"key":"CIT0004-20250902","doi-asserted-by":"crossref","first-page":"E63","DOI":"10.1002\/dc.24889","article-title":"Cytologic features of small cell melanoma","volume":"50","author":"Satturwar","year":"2022","journal-title":"Diagn Cytopathol"},{"key":"CIT0005-20250902","doi-asserted-by":"crossref","first-page":"788","DOI":"10.1111\/cup.12192","article-title":"Rosette-like structures in the spectrum of spitzoid tumors","volume":"40","author":"Arps","year":"2013","journal-title":"J Cutan Pathol"},{"key":"CIT0006-20250902","doi-asserted-by":"crossref","first-page":"349","DOI":"10.4103\/ijmpo.ijmpo_84_16","article-title":"Round cell tumors: Classification and immunohistochemistry","volume":"38","author":"Sharma","year":"2017","journal-title":"Indian J Med Paediatr Oncol"},{"key":"CIT0007-20250902","doi-asserted-by":"crossref","first-page":"790","DOI":"10.1111\/cup.12979","article-title":"Aberrant expression of FLI-1 in melanoma","volume":"44","author":"Ramani","year":"2017","journal-title":"J Cutan Pathol"}],"container-title":["Journal of Cytology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/joc.joc_64_24","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T13:29:19Z","timestamp":1787837359000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/joc.joc_64_24"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7]]},"references-count":7,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.4103\/joc.joc_64_24","relation":{},"ISSN":["0970-9371","0974-5165"],"issn-type":[{"value":"0970-9371","type":"print"},{"value":"0974-5165","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,7]]},"assertion":[{"value":"2024-05-16","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-07-27","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
