Abstract

|
Lymphomatoid papulosis is a chronic self-regressing papulonecrotic or papulonodular skin disease with histologic features suggestive of a malignant lymphoma. It is part of a spectrum of CD30-positive cutaneous lymphoproliferative diseases, is considered as one of indolent cutaneous T-cell lymphomas. The disease is characterized by recurrent crops of pruritic papules at different stages of development that predominantly arise on the trunk and proximal extremities. Clinicopathologically, lymphomatoid papulosis should be differentiated from anaplastic large cell lymphoma. Continued observation of all patients is essential because lymphomas develop in 20% of the patients with lymphomatoid papulosis. Herein, we present two cases of type A lymphomatoid papulosis proven by the histopathologic examination.
