Full Definition
En coup de sabre is a specific variant of linear scleroderma that affects the frontoparietal region of the scalp and forehead, creating a characteristic linear depression that resembles a sword wound. This condition can extend deeper than the skin, potentially affecting underlying bone, muscle, and even brain tissue. In pediatric patients, en coup de sabre may be associated with neurological complications including seizures, headaches, and learning difficulties. The term derives from French, meaning 'sword cut,' reflecting the distinctive appearance of the linear atrophic lesion that often includes alopecia and hyperpigmentation.
