“…A unique fibroepithelial urethral polyp with prostatic glands was incidentally detected in a man in his 60s with BPH. Such polyps are rare and are considered congenital; however, fibroepithelial urethral polyps in adults can also be acquired 1 2. Most of these polyps in adults are asymptomatic,2 as in the present case.…”

“…Fibroepithelial urethral polyps are rare and are usually seen in children between 3 and 9 years of age 1. Although referred to as congenital urethral polyps,1 fibroepithelial urethral polyps are usually asymptomatic in the rare instances in which they are reported in adults 2. The present case describes a man in his 60s with a unique, pathologically confirmed fibroepithelial urethral polyp and its associated heterotopic prostatic glands.…”

“…Most of these polyps in adults are asymptomatic,2 as in the present case. Although hematuria and urinary obstruction have been reported in patients with fibroepithelial urethral polyps,4 5 the clinical symptoms of fibroepithelial urethral polyps are non-specific as other obstructing urethral lesions, such as urethral valve, stricture and lithiasis, show similar symptoms 1. There has been no reports of malignant tumours arising from fibroepithelial urethral polyps and recurrence 2.…”

“…The urethral polyp was considered to be a fibroepithelial polyp with minor prostatic glands. The differential diagnosis of this unusual urethral lesion included urethral caruncle, polypoid urethritis, condyloma acuminatum, papilloma, prostatic urethral polyp and urethral involvement by urinary bladder carcinoma 1 2. A urethral caruncle diagnosis was unlikely as such lesions are typically located at or near the urethral meatus, and their pathology typically shows oedematous and inflamed stroma with dilated subepithelial blood vessels and red blood cell extravasation 3.…”

We describe a man in his 60s with an incidentally detected urethral polyp located in the middle section of his penile shaft. The patient had been suffering from urinary retention for 9 years due to benign prostatic hyperplasia. He was initiated on clean intermittent catheterisation to drain urine 1 year before the detection of the urethral polyp. Holmium laser nucleation of the prostate was performed, and an anterior urethral polyp (5 mm in diameter) was resected. Pathology indicated that the urethral polyp was a fibroepithelial polyp with prostate-specific antigen-immunoreactive heterotopic prostatic glands. There were no problems with urination 6 months after surgery. Fibroepithelial urethral polyps are usually congenital and are rarely described in adults. The clinicopathological features of this polyp, with its uniquely associated minor prostatic glands, are presented.

Objective: To investigate clinical, pathology, and imaging findings associated with inguinal lymph node (LN) metastases in patients with prostate cancer (PCa). Materials and Methods: This was a retrospective single-center study of patients with PCa who underwent imaging and inguinal LN biopsy between 2000 and 2023. We assessed the following aspects on multimodality imaging: inguinal LN morphology; extrainguinal lymphadenopathy; the extent of primary and recurrent tumors; and non-nodal metastases. Imaging, clinical, and pathology features were compared between patients with and without metastatic inguinal LNs. Results: We evaluated 79 patients, of whom 38 (48.1%) had pathology-proven inguinal LN metastasis. Certain imaging aspects— short-axis diameter, prostate-specific membrane antigen uptake on positron-emission tomography, membranous urethra involvement by the tumor, extra-inguinal lymphadenopathy, and distant metastases—were associated with pathology-proven inguinal LN metastases (p < 0.01 for all). Associations with long-axis diameter, fatty hilum, laterality, and uptake of other tracers on positronemission tomography were not significant (p = 0.09–1.00). The patients with metastatic inguinal LNs had higher prostate-specific antigen levels and more commonly had castration-resistant PCa (p < 0.01), whereas age, histological grade, and treatment type were not significant factors (p = 0.07–0.37). None of the patients had inguinal LN metastasis in the absence of locally advanced disease with membranous urethra involvement or distant metastasis. Conclusion: Several imaging, clinical, and pathology features are associated with inguinal LN metastases in patients with PCa. Isolated metastasis to inguinal LNs is extremely rare and unlikely to occur in the absence of high-risk imaging, clinical, or pathology features.
