Sclerosing Adenosis of the Prostate—A Benign Lesion Similar to Prostate Cancer: A Case Report and Literature Review
Sclerosing adenosis of the prostate (SAP) is a rare benign non-neoplastic small acinar hyperplasia. Like sclerosing adenosis of the breast, which is confused with breast cancer, SAP is a trap in the pathological differential diagnosis of benign and malignant lesions of the prostate. We report such a case to help colleagues better distinguish and diagnose such diseases. A 75-year-old patient with SAP had a prostate specific antigen (PSA) level of 11.0 ng/mL, and he had been suffering from progressive dysuria for 3 years. The central glandular area and the right periphery of the prostate were found to have nodular low signals on magnetic resonance imaging (MRI). Prostate biopsy showed that basal cells were positive for P63 and P504s, few basal cells were positive for S-100, and the positive rate of Ki67 was approximately 2%. We consider that the possibility of SAP is high. The patient was treated conservatively and was discharged in good health, free of dysuria and other problems. SAP is a rare benign lesion that is easily misdiagnosed as prostate cancer. The prostatic gland tube has a complete basal cell layer surrounding it, as well as myoepithelial cell metaplasia of basal cells, which is a key trait in distinguishing it from prostate cancer. Although the latest research indicates that SAP does not require treatment, the question of whether it is a risk factor for prostate cancer remains unanswered
The Efficacy and Safety of HoLEP for Benign Prostatic Hyperplasia With Large Volume: A Systematic Review and Meta-Analysis
This meta-analysis was to evaluate the efficacy and safety of holmium laser enucleation of prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH) with large volume. PubMed, Embase, and Cochrane Library databases (until March 2022) were used to search related randomized controlled trials. A total of 11 studies including 1,258 patients were involved. HoLEP could significantly decrease the length of hospital stay and accelerate recovery. In subanalysis, HoLEP had better perioperative outcomes than bipolar transurethral resection of the prostate (B-TURP) and bipolar transurethral enucleation of the prostate (BPEP). The improvement in operative time and enucleation time was better in thulium laser enucleation of the prostate (ThuLEP) than HoLEP. In the follow-up period, the HoLEP decreased post-void residual urine (PVR) in short-term intervals and improved patients’ maximum flow rate (Qmax) and prostate-specific antigen (PSA) in mid- and long-term intervals. In subanalysis, HoLEP presented significant improvements in Qmax, PSA, and quality of life (QoL) than B-TURP, and HoLEP could also improve Qmax than ThuLEP after 6 months of surgery. The HoLEP reduced the risk of postoperative bleeding compared with other surgeries in safety. In our study, we confirmed the advantages of HoLEP in treating BPH when the prostate size was larger than 80 mL, which indicated that HoLEP could be the best choice for treatment of large volume of prostate
