Background: The synchronous diagnoses of three primary malignancies in a patient is rare and represents a difficult treatment challenge. We report a rare case of an 81-year-old male with synchronous triple urogenital cancers including penile squamous cell carcinoma, bladder papillary urothelial carcinoma, and prostate adenocarcinoma.
Case report: The patients presented with a penile lesion with blood draining through the foreskin. Further examination with cystoscopy during the biopsy procedure revealed a 1.5-cm tumor along the left lateral bladder wall and a firm prostate in bilateral lobes. Diagnosis of penile squamous cell carcinoma was confirmed by biopsies of the penile lesions and glans as confirmed by cystoscopy and histological evaluation of the tissue obtained by transurethral resection of the bladder. Biopsies of the prostatic urethra confirmed a diagnosis of prostate adenocarcinoma. All biopsies were performed in a single procedure. Pathology findings revealed moderately differentiated squamous cell carcinoma (p16+) invading the lamina propria of the glans penis, noninvasive low-grade papillary urothelial carcinoma of the bladder, and high-grade prostatic adenocarcinoma (Gleason score 5+5=10) within the prostatic stroma.
Conclusion: Review of the English literature through PubMed search suggests that this specific combination of synchronous triple urogenital cancer is the first documented case of its kind. Incidence, diagnosis, and treatment for the combination of these cancer types are discussed with consideration for concurrent management of three primary cancers.
