Objective: This study aimed to report a unique perineal abscess after placement of a transobturator sling, involving the thighs and obturator regions bilaterally without involving mesh exposure.
Case Report: A 66-year-old woman treated for stress urinary incontinence with a transobturator sling developed a late bilateral obturator infection 30 months after surgery. This complication appeared 6 months after chemotherapy for breast cancer. Sling removal through vaginal and bilateral inguinal incisions was performed. The patient evolved well, without recurrence of the infection or incontinence.
Discussion: This case presents a unique scenario of muscle and skin infection after sling placement without any mesh exposure or vaginal involvement. The occurrence of the infection only after chemotherapy may indicate that immunosuppression had participation on its development. Care should be taken when exposing this mesh in contaminated perineal areas.
