Delayed Diagnosis of Tuberous Sclerosis Complex: A Case Report.

Tuberous sclerosis complex (TSC) is a multisystem genetic disorder with variable clinical expression. We report the case of a 26-year-old woman who presented with characteristic cutaneous findings, including facial angiofibromas, periungual fibromas, and a fibrous cephalic plaque. Further evaluation revealed renal angiomyolipomas and retinal astrocytic hamartomas. Despite a history of childhood seizures, the diagnosis was delayed until adulthood. This case highlights the role of dermatological examination in identifying TSC, particularly in patients with subtle or asymptomatic systemic involvement.
