INTRODUCTION: The effect of synthetic mesh after pelvic organ prolapse surgery on the progression of bladder cancer remains unclear. CASE PRESENTATION: A 79-year-old woman who underwent a tension-free vaginal mesh procedure 8 years prior was diagnosed with carcinoma in situ of the bladder. Although intravesical Bacillus Calmette-Guérin therapy was started, the tumor rapidly became muscle invasive. Laparoscopic radical cystectomy was performed following radiochemotherapy; however, the tumor extended to the left internal obturator muscle along the mesh arm. Pathological findings showed desmoplastic high-grade urothelial carcinoma infiltrating around the mesh. Finally, cancer recurred rapidly in the left internal obturator muscle. CONCLUSION: Synthetic mesh can become an abnormal anatomical pathway for tumor infiltration. Therefore, in high-risk bladder cancer patients who underwent a tension-free vaginal mesh procedure, radical cystectomy should be performed without delay before the tumor invades the perivesical tissue.
