Fibrous tumors of the pleura, liposarcoma, thymoma or lipoma most frequently affect this anatomic area. Surgical exploration and resection are often mandatory to make the definitive diagnosis. We report the case of a 54-year-old women who presented with an epigastric and right sub costal pain. A complete preoperative workup revealed a large tissular and fatty mass in the right costo-diaphragmatic angle suggestive of liposarcoma. Surgical resection resulted in the surprising diagnosis of hamartochondroma.<\/jats:p>","DOI":"10.3390\/curroncol29050281","type":"journal-article","created":{"date-parts":[[2022,5,11]],"date-time":"2022-05-11T10:19:46Z","timestamp":1652264386000},"page":"3489-3493","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hamartochondroma Pleural Lesion Mimicking Liposarcoma: A Case Report"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1174-7655","authenticated-orcid":false,"given":"Gabrielle","family":"Drevet","sequence":"first","affiliation":[{"name":"Department of Thoracic Surgery and Lung Transplantation, Louis Pradel Hospital, Hospices Civils de Lyon, 69677 Bron, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erik","family":"Kovacs","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery and Lung Transplantation, Louis Pradel Hospital, Hospices Civils de Lyon, 69677 Bron, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lara","family":"Chalabreysse","sequence":"additional","affiliation":[{"name":"Department of Pathology, Louis Pradel Hospital, Hospices Civils de Lyon, 69677 Bron, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Delphine","family":"Gamondes","sequence":"additional","affiliation":[{"name":"Department of Radiology, Louis Pradel Hospital, Hospices Civils de Lyon, 69677 Bron, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fran\u00e7ois","family":"Tronc","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery and Lung Transplantation, Louis Pradel Hospital, Hospices Civils de Lyon, 69677 Bron, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,11]]},"reference":[{"key":"ref_1","first-page":"7191363","article-title":"Prediction of Histologic Subtype and FNCLCC Grade by SUVmax Measured on 18F-FDG PET\/CT in Patients with Retroperitoneal Liposarcoma","volume":"6","author":"Li","year":"2021","journal-title":"Contrast Media Mol.
