Persistent Müllerian Duct Syndrome: Understanding the Challenges.

Area of Science:

• Endocrinology
• Pediatric Surgery
• Genetics

Background:

• Persistent Müllerian duct syndrome (PMDS) is a rare autosomal recessive disorder in 46,XY males, characterized by the presence of Müllerian duct remnants.
• It presents challenges in diagnosis and management due to its rarity and varied clinical manifestations.

Observation:

• A case of an infant diagnosed with PMDS at 6 months for bilateral impalpable testes is described.
• Laparoscopy revealed Müllerian structures (uterus, fallopian tubes) and bilateral intra-abdominal testes.
• Gonadal biopsy confirmed normal testicular tissue.

Findings:

• The infant underwent successful bilateral two-stage Fowler-Stephens orchidopexies, with preservation of Müllerian remnants to maintain testicular vascularity.
• At 7-year follow-up, testes are intrascrotal and normal on palpation, with no clinical concerns regarding the Müllerian remnant.
• Surveillance via ultrasound and MRI showed no adverse events related to the Müllerian remnant.

Implications:

• This case underscores the importance of surgical intervention and long-term surveillance in managing PMDS.
• It highlights the need for further research into fertility preservation, malignancy risk, and standardized management protocols for PMDS.
• The findings contribute to the limited understanding of long-term outcomes and optimal care strategies for patients with PMDS.
