[Chronic renal insufficiency associated with tuberous sclerosis]

Area of Science:

• Nephrology
• Oncology
• Genetics

Background:

• Tuberous sclerosis complex (TSC) is a genetic disorder characterized by hamartomatous growths in multiple organs.
• Renal involvement, primarily angiomyolipomas and cysts, is common in TSC, affecting up to 80% of patients.
• However, progression to end-stage renal disease is considered uncommon.

Observation:

• A 37-year-old woman with tuberous sclerosis presented with chronic renal failure.
• This presentation is unusual given the typical renal manifestations of TSC.
• The case prompted a comprehensive review of the literature.

Findings:

• The patient's chronic renal failure, despite renal hamartomatous lesions, represents a rare clinical scenario in tuberous sclerosis.
• Pathological, clinical, diagnostic, and therapeutic aspects of this rare association were discussed.
• Analysis of the literature supports the rarity of this complication.

Implications:

• This case underscores the importance of vigilant renal monitoring in tuberous sclerosis patients, even in the absence of overt signs of severe kidney disease.
• Understanding this rare complication can aid in earlier diagnosis and tailored management strategies.
• Further research into the specific mechanisms leading to renal failure in TSC may improve patient outcomes.
