Share cases and questions with Physicians on Medscape consult. Sometimes multiple renal cysts can be confused with true polycystic kidney disease. Dermatol Clin. Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin. Pulmonary involvement typically occurs in the second or third decade, with dyspnea, pneumothorax, or chylothorax.
