Myeloid sarcoma in the prostate is exceptionally rare, with fewer than 30 patients reported. Among these, 8 have been observed without a prior diagnosis of a hematolymphoid neoplasm. To date, concurrent prostatic myeloid sarcoma and adenocarcinoma have not been documented in the English-language literature. We present the first 2 myeloid sarcomas in the prostate occurring concurrently with high-grade prostatic adenocarcinoma, identified on core needle biopsy and radical prostatectomy in patients without a prior history of myeloid sarcoma or acute myeloid leukemia (AML), and highlight the associated diagnostic challenges. Both were positive for NPM1 by immunohistochemistry, consistent with\n                    <jats:italic toggle=\"yes\">NPM1<\/jats:italic>\n                    mutation. Neither patient received treatment for myeloid sarcoma\/AML due to multiple comorbidities. One patient succumbed to the disease 44 days after diagnosis, while the other passed away from respiratory failure in the context of multiple comorbidities 2 months after being diagnosed with myeloid sarcoma.\n                  <\/jats:p>","DOI":"10.1177\/10668969251344965","type":"journal-article","created":{"date-parts":[[2025,6,11]],"date-time":"2025-06-11T03:47:04Z","timestamp":1749613624000},"page":"111-118","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Diagnostic Challenges in Identifying Concurrent Myeloid Sarcoma and High-Grade Prostatic Adenocarcinoma Within the Prostate"],"prefix":"10.1177","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-0768-4764","authenticated-orcid":false,"given":"Ting","family":"Zhao","sequence":"first","affiliation":[{"name":"Massachusetts General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3428-4166","authenticated-orcid":false,"given":"Judith A.","family":"Ferry","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James L.","family":"Netreba","sequence":"additional","affiliation":[{"name":"Department of Pathology, Mercy Hospital Oklahoma City, Oklahoma City, OK, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9490-8583","authenticated-orcid":false,"given":"Kristine M.","family":"Cornejo","sequence":"additional","affiliation":[{"name":"Massachusetts General Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,6,11]]},"reference":[{"key":"e_1_3_2_2_2","volume-title":"Haematolymphoid Tumours","author":"WHO Classification of Tumours Editorial Board","year":"2024","unstructured":"WHO Classification of Tumours Editorial Board.
