  1. Abbreviations: ANED: Alive, no evidence of disease; TSC: Tuberous sclerosis complex; AML: Angiomyolipoma; NA: Not available; Chr.: chromosome
  2. aMultiple small AMLs (tumorlets) in the renal parenchyma.
  3. bEosinophilic solid and cystic RCC (x2), low-grade oncocytic tumor (LOT) (x3), and numerus small AMLs, considered “silent TSC”.
  4. cOne additional “TSC-associated oncocytic tumor” (1.9 cm), with morphologic similarity to LOT (information provided courtesy Dr. Sounak Gupta, Mayo Clinic).
