Introduction: Prostate cancer with inguinal hernia sac metastasis is a rare event. Herein we report a rare case of prostate cancer with inguinal hernia metastasis.
Case report: An 83-year-old male patient received hernioplasty and the submitted specimen was incidentally found to have adenocarcinoma of prostatic microscopically. The patient had undergone transurethral resection of prostate for three times in the latest 10 years. Benign pathological results were found in all three transurethral resection of prostate. The patient received serum PSA checkup while PSA level was 40.37 ng/ml. He received trans-rectal ultrasound-guided prostate biopsy and prostate adenocarcinoma with Gleason score 4+5 was noted.
Discussion: Inguinal hernia sacs obtained from hernioplasty are routinely sent for pathological examination in some medical facilities although meaningful results are rare. A retrospective study released in 2014 presented only 11 cases (0.35%) of malignancy in a total of 3117 specimens while one third of patients had preexisting malignancies before operations. There were only sporadic case reports on the prostate cancer disclosed in hernia sacs, while nearly all cases displayed metastasis found in the inguinal hernia sac. These findings suggested advanced nature of the disease and a diminished survival time. This report reminds us of the polymorphic characteristics of the prostate cancer and its possibility of metastasis in an unusual way.
