Concurrent hepatic and renal angiomyolipomas in tuberous sclerosis complex

Area of Science:

• Oncology
• Genetics
• Rare Diseases

Background:

• Tuberous sclerosis complex (TSC) is a genetic disorder characterized by the development of benign tumors (hamartomas) in various organs.
• Renal angiomyolipomas (AMLs) are the most common and clinically significant manifestation in TSC patients, leading to significant morbidity.
• Hepatic involvement, such as hepatic AMLs or other lesions, is considered uncommon in TSC.

Purpose of the Study:

• To review the literature on hepatic involvement in Tuberous Sclerosis Complex.
• To highlight the rarity and underreporting of liver manifestations in TSC patients.
• To emphasize the importance of considering hepatic involvement in the differential diagnosis of liver lesions in TSC.

Main Methods:

• Systematic literature search using keywords such as 'Tuberous Sclerosis Complex', 'TSC', 'hepatic involvement', 'liver', and 'angiomyolipoma'.
• Review and synthesis of case reports and series describing hepatic lesions in TSC patients.
• Analysis of the frequency, type, and clinical presentation of hepatic involvement in TSC.

Main Results:

• Hepatic involvement in TSC is infrequently reported compared to renal or neurological manifestations.
• Reported hepatic lesions in TSC include angiomyolipomas, focal nodular hyperplasia, and adenomas.
• Clinical presentation of hepatic lesions in TSC can range from asymptomatic to symptomatic, with potential complications like bleeding.

Conclusions:

• Hepatic involvement, though rare, can occur in Tuberous Sclerosis Complex and should be considered in the clinical evaluation.
• Increased awareness and reporting of hepatic manifestations are needed to better understand their prevalence and clinical significance.
• Further research may elucidate the specific mechanisms underlying hepatic lesion development in TSC.
