Primary cutaneous marginal zone B-cell lymphoma.
Primary cutaneous marginal zone B-cell lymphoma (PCMZL) is included as one of the major types of primary cutaneous B-cell lymphoma in the revised World Health Organization-European Organization for Research and Treatment of Cancer classification. Clinically, PCMZL is an indolent disease and has an excellent prognosis. PCMZL is composed of a polymorphous infiltrate that includes centrocyte-like,...
متن کاملPrimary cutaneous marginal zone B-cell lymphoma: clinical and therapeutic features in 50 cases.
BACKGROUND Primary cutaneous marginal zone B-cell lymphoma (PCMZL) is a low-grade B-cell lymphoma that originates in the skin, with no evidence of extracutaneous disease. Studies focusing on the optimal treatment of PCMZL have not been published thus far. We describe 50 patients with PCMZL to further characterize clinical characteristics and outcome and, in particular, to evaluate our current t...
متن کاملMarginal Zone B-cell lymphoma
Extra-nodal MZBCL of MALT type (7% of all NHL) is an indolent disease involving most often the stomach, where it usually follows chronic gastritis due to Helicobacter pylori (HP) infection. The disease may also localize in the lung, the thyroid, the salivary gland, the orbit. Splenic MZBCL (1% of all NHL on histologic samples) usually, though not invariably, presents splenomegaly associated cir...
متن کاملLetter: Primary cutaneous marginal zone B cell lymphoma of the face: a challenging diagnosis.
The primary cutaneous marginal zone B cell lymphoma is a small B cell lymphoma, including cells of the marginal zone, lymphoplasmacytic cells, and plasma cells. Clinically it manifests as erythematous or erythematous-violaceous papules, plaques, or nodules, single or multiple, most often located to the extremities. Its course is usually indolent, with a survival at 5 years of approximately 97 p...
متن کاملAbsence of MALT1 translocations in primary cutaneous marginal zone B-cell lymphoma.
The implication of MALT1 gene in the pathogenesis of primary cutaneous marginal zone B-cell lymphomas (PCMZL) has been a matter of controversy. We examined the presence of MALT1 translocations in a series of 23 PCMZL. FISH assay with a MALT1 dual color break apart translocation probe revealed the absence of MALT1 translocations in all cases.
