Kidney Tumors If you have kidney issues related to tuberous sclerosis complex (TSC), the most important thing you can do is keep appointments with your doctor. Tuberous sclerosis complex (TSC) is an autosomal-dominant disorder. Correct diagnosis of this syndrome is imperative, not only by detecting cutaneous manifestations at physical examination but also by recognizing the characteristic multimodality imaging findings. Tuberous sclerosis (TS) is an autosomal dominant inherited neurocutaneous syndrome characterized by a variety of hamartomatous lesions in various organs.
