title: Pagetoid reticulosis: a case report and review of the literature.
abstract: The histologic finding of a pagetoid epidermotropic growth pattern is associated with a variety of conditions that range from reactive to neoplastic in nature. Included among these conditions is the uncommon skin disorder pagetoid reticulosis. Pagetoid reticulosis may present clinically as a solitary, indolent plaque-like lesion. Conversely, it may manifest as a more generalized clinically aggressive disease. The generalized form may develop into systemic lymphoma, leading to severe morbidity and death. We present a case of pagetoid reticulosis of the perioral region, a rare anatomic site for this condition. Histopathologic and immunohistochemical findings were consistent with a diagnosis of isolated pagetoid reticulosis. This review discusses the nature of pagetoid reticulosis and addresses past and current concepts regarding the condition.
