<p>Tuberous sclerosis complex (TSC) is an autosomal dominant disorder which can have manifestations in the kidneys, along with other organ systems. Children with TSC may develop kidney lesions at any point during childhood, and typically these are angiomyolipomata (AML) and/or kidney cysts. Children may also have hypertension associated with TSC-associated kidney disease, and rarely reduced kidney function. New guidelines for the management of TSC-associated kidney disease in children and adults were published in 2024. This educational review summarises the relevant clinical aspects of these guidelines for paediatric nephrologists through a series of four clinical cases. These cases cover management of hypertension, frequency of follow-up and frequency of kidney imaging. Difficult clinical scenarios are reviewed, such as the management of <i>TSC2-PKD1</i> contiguous gene syndrome and the management of large AMLs in children with TSC.</p> Graphical abstract <p></p>
