We report a case of an isolated peritoneal metastasis of prostate cancer in a patient without other metastatic sites and a history of prostate surgery. A 63-year-old male with locally advanced prostate cancer without known distant metastasis on androgen deprivation therapy presented with abdominal distension that had persisted for a month. Abdominopelvic computed tomography (CT) showed gastric wall thickening and a moderate amount of ascites. The gastroscopy showed hyperemic mucosal patches on the antrum body. A cytological examination of the ascites fluid was negative for malignant cells. Diagnostic laparoscopy showed multiple nodules in the peritoneum. A biopsy was performed. Histological findings were compatible with metastatic carcinoma of the prostate, which was immunohistochemically positive for pan-cytokeratin, the androgen receptor, and prostate-specific antigen (PSA). The patient was then treated with abiraterone acetate. After 1 month of treatment, both ascites and the PSA value decreased. We describe an extremely rare case of isolated peritoneal carcinomatosis from prostate cancer without any organ metastasis or history of surgery. Clinicians should be aware of these very rare metastases of prostate cancer. Hormonal therapy may be helpful for such cases.<\/jats:p>","DOI":"10.3390\/curroncol29070351","type":"journal-article","created":{"date-parts":[[2022,6,21]],"date-time":"2022-06-21T21:55:19Z","timestamp":1655848519000},"page":"4423-4427","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Isolated Peritoneal Metastasis of Prostate Cancer Presenting with Massive Ascites: A Case Report"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8162-8657","authenticated-orcid":false,"given":"Hee Ryeong","family":"Jang","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Kangwon National University Hospital, Kangwon National University School of Medicine, Chuncheon-si 24289, Gangwon-do, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6243-6868","authenticated-orcid":false,"given":"Kyoungyul","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kangwon National University Hospital, Kangwon National University School of Medicine, Chuncheon-si 24289, Gangwon-do, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8482-9198","authenticated-orcid":false,"given":"Kyu-Hyoung","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Kangwon National University Hospital, Kangwon National University School of Medicine, Chuncheon-si 24289, Gangwon-do, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7","DOI":"10.3322\/caac.21654","article-title":"Cancer Statistics, 2021","volume":"71","author":"Siegel","year":"2021","journal-title":"CA Cancer J.
