Abstract:
Persistent müllerian duct syndrome is a rare form of male pseudohermaphroditism. It is usually diagnosed in the early years of life. A case is reported of normal male appearance with bilateral undescended testicles and a right inguinal hernia. On exploration a uterus, two fallopian tubes and a testis were found in the hernial sac. As these patients have an increased risk of gonadal tumours they should be kept under long-term review.
Insights
Persistent Müllerian Duct Syndrome (PMDS) is a rare disorder causing male pseudohermaphroditism, often diagnosed in childhood. This case highlights a male with internal female reproductive organs, emphasizing the need for long-term monitoring due to cancer risks.
Area of Science:
- Endocrinology
- Genetics
- Pediatric Surgery
Background:
- Persistent Müllerian Duct Syndrome (PMDS) is a rare intersex condition characterized by the presence of Müllerian structures (uterus, fallopian tubes) in otherwise normal 46,XY males.
- It results from mutations in the anti-Müllerian hormone (AMH) gene or its receptor (AMHR2), impairing Müllerian duct regression during fetal development.
Observation:
- A case report of a patient with a typical male phenotype presenting with bilateral undescended testicles and a right inguinal hernia.
- Surgical exploration revealed intra-abdominal female reproductive organs, including a uterus and fallopian tubes, alongside a testis within the hernial sac.
Findings:
- The presence of a uterus and fallopian tubes in a phenotypically male individual confirms the diagnosis of Persistent Müllerian Duct Syndrome.
- Undescended testicles and inguinal hernias are common clinical manifestations associated with PMDS.
Implications:
- Individuals with PMDS have an elevated risk of developing gonadal tumors, particularly in undescended testes.
- Long-term medical surveillance and management are crucial for early detection and treatment of potential complications, including malignancies.
