Abstract Introduction: Persistent Müllerian duct syndrome (PMDS) is a rare disease occurring in men with an otherwise completely normal phenotype, in which female internal sex organs are present, including a uterus, fallopian tubes, cervix, and vagina. We report a case of bilateral recurrent inguinal hernia due to PMDS treated by transabdominal preperitoneal repair (TAPP). Patient concerns: A 72-year-old male presented with a complaint of swelling on both sides of the groin. The patient had undergone bilateral inguinal hernia suture repair 50 years ago. Diagnosis: Bilateral recurrent inguinal hernia Interventions: TAPP was performed. There was a fibrous structure linking the left and right hernia orifice and a muscular structure in the hernia sac on the left. We noticed that the muscular structure was a vagina and fibrous structure was the salpinx, and we diagnosed the patient with PMDS. Supravaginal hysterectomy and right salpingectomy were performed. After that a preperitoneal mesh repair was performed for bilateral inguinal hernia. Outcomes: Histologically, the diagnosis was confirmed as PMDS. The patient had an uneventful recovery. Conclusion: This case is the first case of bilateral recurrent inguinal hernia due to PMDS managed by TAPP.
