Its diagnosis relies on the recognition of pleomorphic lipoblasts (PLBs), whose numbers vary considerably. Because few large fine\u2010needle aspiration (FNA) biopsy studies exist, the authors review their experience with PLPS.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>The authors\u2019 cytopathology files were searched for PLPS with histopathologic verification. FNA biopsy smears were performed via standard techniques.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Twenty cases from 20 patients (male\/female ratio, 2.3\/1; age range, 22\u201077\u2009years; mean age, 58\u2009years) met the inclusion criteria. All had tissue confirmation. Biopsy sites included the following: thigh (11 [55%]), upper extremity (4 [20%]), axilla (2 [10%]), neck (1 [5%]), chest wall (1 [5%]), and mediastinum (1 [5%]). Aspirates were from primary (17 [85%]), locally recurrent (2 [10%]), and metastatic neoplasms (1 [5%]). The FNA diagnoses were PLPS (10 [50%]), myxofibrosarcoma (4 [20%]), LPS (2 [10%]), sarcoma (2 [10%]), and high\u2010grade malignant neoplasm (2 [10%]). Smears showed thick cell clusters and dissociated single forms. Pleomorphic, epithelioid, and bizarre cell\/nuclear shapes were common. PLBs were absent, rare, or unnoticed in 45%. In 25%, smears dominated by myxoid stroma were diagnosed as high\u2010grade myxofibrosarcoma or myxoid LPS. Ancillary testing performed in 5 cases had limited diagnostic efficacy.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>FNA biopsy of PLPS, although able to successfully recognize malignancy, suffers from a sampling bias due to an inability to capture or recognize PLBs in a significant proportion of cases secondary to the heterogeneous composition of this neoplasm.;<\/jats:p><\/jats:sec>","DOI":"10.1002\/cncy.22580","type":"journal-article","created":{"date-parts":[[2022,4,21]],"date-time":"2022-04-21T13:46:39Z","timestamp":1650548799000},"page":"705-713","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Pleomorphic liposarcoma: A clinicopathologic study of 20 <scp>FNA<\/scp> cases"],"prefix":"10.1002","volume":"130","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0531-2690","authenticated-orcid":false,"suffix":"Jr.","given":"Paul E.","family":"Wakely","sequence":"first","affiliation":[{"name":"Department of Pathology The Ohio State University Wexner Medical Center  Columbus Ohio USA"},{"name":"James Cancer Hospital and Solove Research Institute  Columbus Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3652-698X","authenticated-orcid":false,"given":"Sintawat","family":"Wangsiricharoen","sequence":"additional","affiliation":[{"name":"The Johns Hopkins Hospital  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syed Z.","family":"Ali","sequence":"additional","affiliation":[{"name":"The Johns Hopkins Hospital  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,4,21]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"45","volume-title":"WHO Classification of Tumours Editorial Board.
