title: Diffuse large B-cell lymphoma mimicking advanced basal cell carcinoma.
abstract: Primary cutaneous B-cell lymphomas (PCBCLs) are made up of a heterogenous group of B-cell lymphoproliferative diseases confined to the skin at the time of diagnosis with no evidence of extracutaneous involvement. With early diagnosis and adequate treatment, PCBCLs as a group has excellent prognosis, with about a 95% survival rate at five years. We report a case of diffuse large B-cell lymphoma (DLBCL) in a 52-year-old woman presenting as a fungating skin ulcer mimicking advanced basal cell carcinoma. Review of available literature showed most studies of PCBCLs being done on Europeans with no universally acceptable system of classification. Clinical findings, diagnostic evaluations and treatment outcomes of PCBCLs are discussed with emphasis on comparison of European Organization for Research and Treatment of Cancer (EORTC) and the World Health Organization (WHO) Classification of Neoplasms of the Hematopoietic and Lymphoid Tissue classification systems.
