What is a distinctive feature of skin lesions in tuberous sclerosis?

A distinctive feature of skin lesions in tuberous sclerosis is their irregular leaflike borders. These lesions, known as angiofibromas or fibrous cephalic plaques, appear primarily on the face and have a characteristic leaf-like or mazelike morphology. This irregularity is a hallmark of the condition and helps differentiate these lesions from other types of skin manifestations that may present with more regular, circular borders or even flat, yellowish appearances.

The appearance of these lesions can vary, but the presence of irregular borders provides a visual cue that aligns with the diagnostic criteria for tuberous sclerosis. Being aware of the unique characteristics of these lesions is crucial for healthcare professionals, as it aids in properly identifying and diagnosing tuberous sclerosis in patients.
