Primary cutaneous follicular helper T (TFH)-cell lymphoma has recently been proposed, and is characterized by proliferation of malignant T cells expressing TFH-cell markers, such as CXCL13, accompanied by numerous reactive B cells. We report here a patient whose skin histology showed massive infiltration of both T and B cells, with a proliferation of arborizing high endothelial venules and foll...
Primary pancreatic lymphoma is a rare extranodal manifestation of any histopathologic subtype of B cell non-Hodgkin's lymphoma that predominantly involves the pancreas. It comprises less than 0.2% of pancreatic malignancies and less than 0.7% of non-Hodgkin's lymphomas. This lymphoma is almost never suspected clinically. It is usually diagnosed by surgical exploration for suspected adenoca...
Plasmablastic lymphoma is a rare subtype of diffuse large B-cell lymphoma more frequently diagnosed in immunosuppressed patients, mainly HIV-infected.

Classification of primary cutaneous lymphomas (PCLs) is the subject of ongoing controversy. Based on a series of 556 patients, the applicability of the European Organization for Research and Treatment of Cancer (EORTC) classification for PCLs was assessed and compared to the proposed World Health Organization (WHO) classification of hematologic malignancies. The large majority of patients could...
PURPOSE In the new WHO-European Organisation for Research and Treatment of Cancer (WHO-EORTC) classification for cutaneous lymphomas three major groups of primary cutaneous B-cell lymphoma (CBCL) are distinguished: primary cutaneous marginal zone B-cell lymphoma (PCMZL) and primary cutaneous follicle center lymphoma (PCFCL) with a good prognosis, and primary cutaneous large B-cell lymphoma, leg...
OBJECTIVES To describe clinicopathologic features and to identify prognostic factors in a large series of primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL LT), as defined in the recent World Health Organization-European Organization for Research and Treatment of Cancer classification of cutaneous lymphomas. DESIGN Retrospective multicenter study from the French Study Group on...
ABSTRACT The report describes the clinic of an aggressive non-Hodgkin lymphoma, primary cutaneous diffuse large-B cell leg type (PCDLBCL-LT), and shows its relevance for addressing case a rare with complex diagnosis and, in most cases, late as there are few studies reported on subject. Since it is pathology, essential to have dissemination knowledge assist early disease consequently, choice mor...
most bladder tumors are epithelial in origin. nonepithelial cancers are rarely located in the bladder. sarcomas are the most common malignancies among nonepithelial cancers. primary bladder lymphoma is rare and mostly low grade. here, we have reported a case of diffuse large cell lymphoma of the bladder. the patient, a 64-year-old man, had urinary frequency for 18 months. abdominal sonography i...
