Primary renal lymphoma presenting with hypertension

Area of Science:

• Oncology
• Pediatric Nephrology

Background:

• Primary renal lymphoma (PRL) is an exceptionally rare malignancy, infrequently diagnosed in pediatric populations.
• Typical PRL presentations involve hematuria, flank pain, abdominal mass, and significant weight loss, predominantly in adult patients.

Observation:

• This report details a pediatric case initially presenting with hypertension, without the classic PRL symptoms.
• The patient was asymptomatic, underscoring the diagnostic challenge posed by atypical presentations.

Findings:

• The child was diagnosed with primary renal lymphoma, an uncommon finding in this age group and clinical context.
• Hypertension was the sole presenting clinical sign leading to the diagnosis.

Implications:

• This case expands the spectrum of clinical manifestations for primary renal lymphoma in children.
• It emphasizes the importance of considering rare diagnoses, including PRL, in pediatric patients with unexplained hypertension.
