Tuberous sclerosis complex (TSC) is an autosomal dominant hereditary disease that affects multiple organs and systems throughout the body. TSC-associated kidney disease is the leading cause of death in adult TSC patients. This article retrospectively analyzed the characteristics of one TSC-related renal giant angiomyolipoma(RAML)treated with surgery. The patient, 25 years old, was diagnosed with tuberous sclerosis complex in 2000 due to multiple maculopapular rashes on both cheeks. At a regular follow-up in July 2019, imaging examinations revealed a tumor in the left lower quadrant with a maximum cross-sectional area of 16 cm×7 cm. Genetic testing showed a loss of heterozygosity in the EX18_ 41 of TSC2. After the diagnosis was confirmed, open left partial nephrectomy was performed, during which multiple tumors were found on the kidney surface and the largest one was located on the ventral side with a diameter of approximately 20 cm. After the renal artery was occluded, kidney tumors were completely enucleate. Postoperative pathological confirmed the diagnosis of angiomyolipoma. This case provides a reference for the treatment of TSC-related renal giant hamartoma.
