Bilateral morphea en coup de sabre: a rare presentationof linear morphea

Morphea en coup de sabre is a form of linear localized scleroderma that can lead to cicatricial alopecia when it affects the scalp. Typically unilateral, it may also involve neurological and eye complications. This document presented a rare case of bilateral morphea en coup de sabre in a young man, which developed after a childhood head trauma. The condition caused linear alopecia on the scalp and right eyebrow, with lesions that progressed over 4 years, remained inactive for 6 years, and then resumed progression. Despite experiencing repeated frontal headaches, the patient's neurological and ocular exams were normal. Diagnosis was confirmed through dermoscopy and histopathology, highlighting the case's uniqueness due to its bilateral nature, trauma history, and disease recurrence.
