MORICZ, Claudia Zavaloni Melotti de and SANCHES JR., José Antonio. Lymphoproliferative processes of the skin: Part 1 - Primary cutaneous B-cell lymphomas. An. Bras. Dermatol. [online]. 2005, vol.80, n.5, pp. 461-471. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962005000600003.
Primary cutaneous B-cell lymphomas comprise a group of malignant neoplasms originated from the B-cell lymphoid lineage, of the non-Hodgkin type. The diagnostic routine of cutaneous B-cell lymphoproliferative processes consists of a skin biopsy for histopathological, immunohistochemical and gene rearrangement analysis. The classification of primary cutaneous lymphomas is still controversial. The currently most usual classifications are those proposed by the World Health Organization (WHO) and by the European Organization for Research and Treatment of Cancer (EORTC). The recently proposed WHO-EORTC consensus classification should replace them. However, despite recent progress in this field, there are still controversies and difficulties, mainly regarding the diagnosis and classification of cutaneous B-cell lymphomas.
