Background: Holmium laser enucleation of the prostate (HoLEP) has proven to be effective in benign proliferations of the prostate resulting in large prostatic volumes. It is a less-invasive surgical alternative to transurethral resection and surgical resection. Prostatic adenocarcinoma can incidentally be found in the enucleated tissue. Occasionally, nonadenocarcinomatous forms of neoplasia occur such as sarcoma. Case Presentation: Two male patients, both 65 years old, undergo HoLEP for gigantic prostates. The first patient presented with recurrent hematuria and clot retention. After HoLEP, the patient voiding symptoms improved. Pathologic immunostaining of the tissue showed spindle cell proliferation consistent with stromal tumor of uncertain malignant potential (STUMP). The second patient presented with acute urinary retention and subsequently underwent HoLEP. Pathologic examination of the enucleated tissue was consistent with prostatic stromal sarcoma. Conclusion: HoLEP is a well-established surgical treatment for gigantic proliferations of benign prostatic tissue. Occasionally, patients who are candidates for HoLEP may have a rare underlying pathologic condition such as a sarcoma or a STUMP. Exclusion of underlying malignant processes in massive prostates is necessary before operating.
