Wilms Tumor in Child With Trisomy 18 and Horseshoe Kidney

Area of Science:

• Pediatric Oncology
• Clinical Genetics
• Nephrology

Background:

• Trisomy 18 (Edwards syndrome) is a genetic disorder linked to congenital anomalies, including renal malformations.
• Horseshoe kidney is a common renal abnormality, and its association with Trisomy 18 increases the risk of certain complications.
• Mosaic Trisomy 18 may present with milder phenotypes but carries a higher risk for neoplasms, particularly Wilms tumor.

Observation:

• A case is presented involving a patient with Trisomy 18 and a horseshoe kidney.
• The patient developed Wilms tumor, a pediatric renal malignancy frequently observed in children with Trisomy 18.
• This observation underscores the confluence of these three specific conditions in a single patient.

Findings:

• The co-occurrence of Trisomy 18, horseshoe kidney, and Wilms tumor presents a complex clinical scenario.
• Understanding the interplay between these conditions is crucial for accurate diagnosis and risk assessment.
• The case provides valuable insights into the management of pediatric patients with multiple coexisting conditions.

Implications:

• Early recognition and surveillance for Wilms tumor are vital in Trisomy 18 patients with renal anomalies.
• Multidisciplinary management involving genetics, oncology, and nephrology is essential for optimal patient care.
• This case contributes to the literature, aiding in the development of tailored treatment protocols for similar complex pediatric cases.
