摘要：Background Cutaneous T cell lymphoma (CTCL) has a variable presentation and comprises a broad diagnostic group. Histologic and immunophenotypic confirmation is needed to establish a precise diagnosis. Once the categorization is determined,prognosis and therapeutic algorithms unfold. Primary cutaneous,CD-30+,Anaplastic large T-cell lymphoma represents an indolent form of CTCL that often spontaneously involutes. CTCL is a broad diagnosis encompassing a spectrum of disease. The European Organization for Research and Treatment of Cancer (EORTC)Cutaneous Lymphoma Project recognizes mycosis fungoides (MF),cutaneous CD30-positive large-cell lymphoma,and lymphomatoid papulosis as CTCLs with indolent clinical behavior [1]. Clinical presentation and immunohistochemistry together are needed to determine the subtype of CTCL,which guides proper management.
