Myeloid sarcoma of female breast is a rare presentation of acute myeloid leukemia (AML). The tumor mass may precede or occur concurrently with AML, CML, myeloproliferative disorders, and/or myelodysplastic syndromes. Histologically, it looks like a large cell lymphoma and can be misdiagnosed. A case refe...

Breast is an uncommon site of extra nodal lymphoma accounting for 2.2% all lymphomas. B cell lymphomas are more common than T types. The most subtype Diffuse Large Cell Lymphoma. very challenging to diagnose as it has nonspecific clinical and radiological features. We report a rare case primary in 20-year-old female. It was misdiagnosed abscess on ultrasound suppurative mastitis fine needle asp...

Literature review shows that hepatitis C infection may increase the risk of non-hodgkin lymphoma. Reactivation of hepatitis B infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. We present hepatitis B surface (HBs) antigenemia and concurrent hepatitis C virus (HCV) seropositivity in a case of hairy cell leukemia. Key Words: Hairy cell leukemi...

the occurrence of langerhans cell histiocytosis (lch) in a patient with lymphoma is an indication of a probable relationship between them. the two conditions have similarities both clinically and histopathologically. occurrence of these two conditions in the same patient, particularly not simultaneously, is rare. according to different management and treatment of these conditions, exact histopa...

micrornas are 19-22 nucleotide rnas involved in such important processes as development, proliferation, differentiation and apoptosis. different mirnas are uniquely expressed in lymphoid t cells, and play a role indevelopment and differentiation of various subtypes by targeting their target genes. recent studies have shown that aberrant mirna expression may be involved in t cell leukemogenesis ...

Survival of patients with multiple myeloma has improved substantially because of availability of new therapies including autotransplants, immunomodulating drugs and proteasome-inhibitors. Second primary cancers have emerged as an important determinant of morbidity and mortality among cancer survivors. Even though there is an increased risk of new cancers of the lymphoreticular and haematopoetic...

Mycosis fungoides (MF), the most common type of cutaneous T-cell lymphoma, is histologically characterized by atypical T lymphocytes with cerebriform nuclei that infiltrate the epidermis. Alope
