Los linfomas cutáneos primarios de células T distintos la micosis fungoide, el síndrome Sézary y los procesos linfoproliferativos positivos para CD30 son poco frecuentes, representan menos del 5% todos cutáneos; generalmente se caracterizan por un fenotipo citotóxico habitualmente presentan comportamiento clínico agresivo. A menudo, pacientes o desarrollan enfermedad extracutánea después diagnó...
Observation: The CD30 antigen is a type-1 transmembrane glycoprotein which is a member of the tumor necrosis factor receptor family and may be expressed on activated B and T cells. CD30+ lymphoproliferative disorders (CD30+ LPDs) mainly include primary cutaneous CD30+ anaplastic large-cell lymphoma (pcALCL) and lymphomatoid papulosis (LyP). Other CD30 +LPD showing skin lesions are large cell tr...
definitive diagnosis should be based on the presence or absence of extracutaneous disease at diagnosis. Testicular B-cell lymphoma can also affect the skin and its pathologic and immunophenotypic characteristics are indistinguishable from those of PCDLBCL, leg type; routine testicular examination is therefore recommended in appropriate cases. We have reported a case of systemic DLBCL diagnosed ...
Introduction: Primary gastric lymphoma (PGL) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (IHC) and genetic analysis. Case Presentation: A 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise IHC and staging in another center. Inappropriate IHC after surgery showed diffuse large B-cell lymphom...
Primary cutaneous T- and B-cell lymphomas are a heterogeneous group of diseases with varied clinical presentations and prognosis. The use of new molecular, histological, and clinical criteria has improved their recognition. Cutaneous B-cell and T-cell lymphomas are seldom found together in the same patient. Here we report a rare case of mycosis fungoides variant of a cutaneous T-cell lymphoma (...
