Multiple unilateral angiofibromas with a hypopigmented patch as a possible presentation of tuberous sclerosis complex (TSC)

Tuberous sclerosis complex (TSC), known as Bourneville’s disease or epiloia, is an autosomal dominant inherited disorder that may affect numerous organ systems. TSC has many forms of clinical presentation. The cutaneous features of TSC include facial angiofibromas, shagreen patches, ash leaf hypopigmented macules, periungual fibromas, forehead fibrous plaques, confetti hypopigmentation, and poliosis. Rarely, the angiofibromas in TSC have a segmental distribution. It has been suggested that the segmental expression of tuberous sclerosis may result from a postzygotic mutation. The aim of this concise communication was to describe a patient with unilateral angiofibromas associated with a hypopigmented patch. No other features of TSC were present. We think this could have been a rare presentation of TSC.
