Linear Psoriasis in a Pediatric Patient Successfully Treated With Ixekizumab

Linear psoriasis is a rare clinical presentation of psoriasis characterized by erythematous scaly plaques distributed along Blaschko's lines. We describe an 8-year-old male with a linear Blaschkoid plaque in which biopsy findings and clinical history were consistent with linear psoriasis. The lesion showed only mild improvement with topical steroid therapy but exhibited significant clearance with the biologic agent ixekizumab, an IL-17A inhibitor. With limited supporting literature regarding management, this case report illustrates the clinical manifestation, diagnosis, and an effective management strategy for linear psoriasis in a pediatric patient.
