Renal leiomyoma associated with tuberous sclerosis

Area of Science:

• Nephrology
• Oncology
• Genetics

Background:

• Tuberous sclerosis complex (TSC) is a genetic disorder characterized by the development of benign tumors in various organs.
• Renal manifestations are common in TSC, with angiomyolipomas and cysts being the most frequently observed lesions.
• Other renal tumors are infrequently associated with TSC, making their identification significant.

Observation:

• This study presents a case of a patient diagnosed with tuberous sclerosis complex.
• The patient presented with a fever of unknown origin, prompting an extensive diagnostic investigation.
• During the investigation, an incidental renal leiomyoma was detected.

Findings:

• The primary finding is the incidental detection of a renal leiomyoma in a patient with tuberous sclerosis complex.
• Renal leiomyomas are rare tumors and their association with TSC is exceptionally uncommon.
• This case highlights a deviation from the typical renal pathology seen in tuberous sclerosis.

Implications:

• The presence of a renal leiomyoma in a TSC patient expands the spectrum of known renal pathologies associated with the condition.
• This finding may necessitate a broader differential diagnosis for renal masses in TSC patients.
• Further research into the genetic and molecular mechanisms underlying rare renal tumors in TSC is warranted.
