We report a rare instance of a 22\u2010year\u2010old female with recurrent epithelioid MPNST metastasizing to cervical lymph nodes and pleural fluid\u2014a phenomenon rarely documented in literature. Clinical history, cytomorphological assessment, and immunohistochemistry were pivotal in establishing the diagnosis. This case underscores the diagnostic complexity and extreme rarity of epithelioid MPNST metastasizing to serous cavities.<\/jats:p>","DOI":"10.1002\/dc.70070","type":"journal-article","created":{"date-parts":[[2025,12,16]],"date-time":"2025-12-16T10:38:19Z","timestamp":1765881499000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["When the Rare Becomes Rarer: Metastasis of Epithelioid Malignant Peripheral Nerve Sheath Tumor (\n                    <scp>MPNST<\/scp>\n                    ) to Lymph Node and Pleural Fluid"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-9693-8297","authenticated-orcid":false,"given":"Nitika","family":"Gupta","sequence":"first","affiliation":[{"name":"Department of Pathology, Homi Bhabha Cancer Hospital and Research Centre, Tata Memorial Centre, Homi Bhabha National Institute (HBNI) New Chandigarh  Punjab India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nilay","family":"Nishith","sequence":"additional","affiliation":[{"name":"Department of Pathology, Homi Bhabha Cancer Hospital and Research Centre, Tata Memorial Centre, Homi Bhabha National Institute (HBNI) New Chandigarh  Punjab India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9297-5400","authenticated-orcid":false,"given":"Pranab","family":"Dey","sequence":"additional","affiliation":[{"name":"Department of Pathology, Homi Bhabha Cancer Hospital and Research Centre, Tata Memorial Centre, Homi Bhabha National Institute (HBNI) New Chandigarh  Punjab India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,16]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"254","volume-title":"Soft Tissue and Bone Tumours","author":"Nielsen G.
