Review Article

Abstract: We report 2 patients with typical clinical findings of circumscribed morphea who on histopathologic examinations had histiocytes (“floating sign”) surrounding individual collagen fibers in the dermis in addition to the key histologic findings of morphea. To our knowledge, there are no previous reports in the medical literature of such a phenomenon. Histopathological findings in idiopathic morphea and morphea-like conditions are reviewed.
