She was found to have an incidental 2\u2009cm pedunculated, solid, and multicystic mass attached to the pelvic floor on laparoscopy. The neoplasm had a variably myxoid and spindle cell pattern with nests and cords of small cells, forming pseudocysts, and true cysts lined by ciliated epithelium which were PAX-8+ and ER+\/PR+. The tumor had the EWSR1::WT1 fusion. Numerous peritoneal nodules less than 1\u2009cm were noted on repeat laparoscopy 3\u2009months later. These had similar features including the ciliated epithelial cysts. Our case illustrates yet another potential variant pattern of DSRCT with Mullerian-like ciliated epithelial cysts.<\/jats:p>","DOI":"10.1177\/10935266241312435","type":"journal-article","created":{"date-parts":[[2025,1,9]],"date-time":"2025-01-09T04:44:51Z","timestamp":1736397891000},"page":"142-147","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Variant Pseudocystic Desmoplastic Small Round Cell Tumor With Heterologous Mullerian Cysts"],"prefix":"10.1177","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9561-4931","authenticated-orcid":false,"given":"Eric I.","family":"Nayman","sequence":"first","affiliation":[{"name":"Department of Pathology, Northwestern University Feinberg School of Medicine, Chicago, IL, USA"},{"name":"Herbert Wertheim College of Medicine, Florida International University, Miami, FL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carole","family":"Brathwaite","sequence":"additional","affiliation":[{"name":"Department of Pathology, Nicklaus Children\u2019s Hospital, Miami, FL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felipe","family":"Pedroso","sequence":"additional","affiliation":[{"name":"Herbert Wertheim College of Medicine, Florida International University, Miami, FL, USA"},{"name":"Department of Pediatric Surgery, Nicklaus Children\u2019s Hospital, Miami, FL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maggie E.","family":"Fader","sequence":"additional","affiliation":[{"name":"Department of Oncology, Nicklaus Children\u2019s Hospital, Miami, FL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Farres","family":"Obeidin","sequence":"additional","affiliation":[{"name":"Department of Pathology, Northwestern University Feinberg School of Medicine, Chicago, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louis P.","family":"Dehner","sequence":"additional","affiliation":[{"name":"Lauren V.
