Background: Cutaneous lymphomas are monoclonal neoplastic proliferations of immune cells most frequently T or B cells that infiltrates skin. Development of new diagnostic methods, particularly those for immunophenotyping, have substantially changed classification of these neoplasms. These reasons prompted us to perform this study. Objective: To re-classify cutaneous lymphomas and pseudoly...

It is a challenging task to diagnose mycosis fungoides (MF), a type of primary cutaneous lymphoma, in the early stages of its development, due to the unspecific presentations associated with the disease. Histopathology and immunohistochemistry conduce to a more definite diagnosis. Presence of atypical T-cells in epidermis and upper dermis is the most significant pathologic finding. Herein...

Localized primary breast lymphoma is very rare. The typical clinical and radiographic presentation of isolated primary breast lymphoma mimics that of breast adenocarcinoma. Histologic diagnosis of primary breast lymphoma relies heavily on Hematoxylin and Eosin pathologic evaluation and immunohistochemical staining. Cytotoxic systemic chemotherapy is the primary treatment for this disease with t...

Background: Comparison of the number of mast cells in the active stage and that in remission in the same patients with ulcerative colitis with immunohistochemical staining remains to be elucidated, and analysis of the number of mast cells in benign and malignant colonic lesions is insufficient. Methods: Using immunohistochemical methods, morphological examinations of mast cells were undertaken ...

Primary hepatic lymphoma is extremely rare. Although the utility of fluorodeoxyglucose (FDG)-positron emission tomography (PET) for imaging extranodal lymphoma has been reported, there is very little literature describing its use in primary hepatic lymphoma. This case report demonstrates the effect of FDG-PET/computed tomography (CT) in a case of unifocal primary hepatic lymphoma and its useful...

BACKGROUND Primary cutaneous B-cell lymphoma manifested by anetoderma has been reported in 7 cases. In all, the secondary anetoderma developed in lesions of marginal-zone lymphoma or posttransplant lymphoproliferative disorder resembling marginal-zone lymphoma. The mechanisms underlying the destruction of elastic tissue in anetoderma are unclear. However, there is growing evidence linking prima...

introduction: a study was made conserning 142 patients who were suffering from gastrointestinal lymphoma, were seen at the department of hematology and oncology, esfahan medical school, during the period 1982-2002. method: all patients had laparotomy, and biopsy of the site lesion. histopathological subtypes were done in the international working formulation. stage groupings were done applying ...
