Persistent Mullerian Duct Syndrome with Embryonal Cell Carcinoma along with Ectopic Cross Fused Kidney

Area of Science:

• Endocrinology
• Urology
• Oncology

Background:

• Persistent Mullerian Duct Syndrome (PMDS) is a rare intersex condition where individuals with male external genitalia possess internal female reproductive structures like a uterus and fallopian tubes.
• This syndrome often goes undiagnosed until later in life, frequently discovered incidentally during investigations for other conditions.
• Cross fused renal ectopia is a congenital anomaly where one kidney is positioned on the opposite side of the abdomen and fused with the other kidney.

Observation:

• A phenotypical male presented with an abdominal mass and bilateral cryptorchidism (undescended testes).
• Diagnostic workup revealed the presence of a uterus and bilateral fallopian tubes, characteristic of PMDS.
• The patient also had an ectopic, cross-fused right kidney and an Embryonal cell carcinoma in the left undescended testis.

Findings:

• The case demonstrates an extremely rare co-occurrence of Persistent Mullerian Duct Syndrome, cross fused renal ectopia, and testicular cancer in a phenotypical male.
• The abdominal mass was identified as an Embryonal cell carcinoma arising from the left undescended testis.
• The anatomical abnormalities included bilateral cryptorchidism and a fused ectopic kidney.

Implications:

• This case underscores the importance of thorough investigation in phenotypical males presenting with ambiguous genitalia or related anomalies.
• The co-existence of PMDS, renal anomalies, and malignancy highlights complex developmental pathways and potential risks.
• Early diagnosis and management are crucial for addressing both the hormonal and oncological aspects of such rare conditions.
