INTRODUCTION Cytotoxic CD8+ T-cell lymphomas are only rarely encountered and thus remain only poorly characterized. Our aim was to collect and correlate clinical and histological data of CD8+ skin lymphoma infiltrates to obtain a proper subtype assignment of CD8+ skin lymphoma infiltrates and to derive putative prognostic markers thereof. METHODS Formalin-fixed and paraffin-embedded (FFPE) ti...
Clinical features and history Cutaneous B-cell lymphomas usually present as one or more erythematous papules or nodules that may coalesce to form plaques. They are usually localized tumors effecting one cutaneous region and rarely ulcerate. There is some regional predilection for various sub-types of tumors; follicle center lymphoma more commonly arises on the scalp, marginal zone B-cell lympho...
BACKGROUND A growing number of studies demonstrate the utility of (18)fluoro-2-deoxyglucose positron emission tomography (FDG-PET) in the management of malignant lymphoma. The results of FDG-PET, however, have not been studied extensively for T-cell and natural killer (NK)-cell neoplasms. PATIENTS AND METHODS We retrospectively evaluated pretreatment FDG-PET scans in 41 patients with T/NK-cel...
BACKGROUND Cutaneous T-cell lymphoma occurring in the context of posttransplant immunosuppression is rare, with 27 cases documented to date. OBSERVATIONS We report 2 new cases of posttransplant cutaneous T-cell lymphoma in patients treated at our institution. Both were male recipients of renal transplants who had undergone transplantation a mean of 5.3 years previously and were taking various...
Background: Primary cutaneous lymphoma is separated into two groups, cutaneous lymphoma (CTCL) and cutaneous B-CELL Lymphoma (CBCL). This study was performed to classify histopathologically and define demographic features of Persian patients with primary cutaneous lymphoma.Methods: Twenty hundred and thirty four patients with primary cutaneous lymphoma who have been referred to Razi Hospital in...
BACKGROUND Peripheral nodal follicular T-cell lymphomas expressing follicular helper T-cell (T(FH)) markers have recently been identified. Such lymphomas are characterized by a nodal neoplastic T-cell proliferation accompanied by numerous reactive B cells and demonstrate some overlap with nodal angioimmunoblastic T-cell lymphoma (AITL). We identified 5 cases of cutaneous T-cell lymphoma with a ...
