uterine lymphoma is a rare disease therefore, information regarding histologic type, immunophenotype of tumor cells and etiologic factors are limited. although secondary involvement of the genital tract occurs in up to 40% of cases• of disseminated lymphoma, lymphoma presenting with primary female genital tract . symptomatology is very unusual. we report a case of b-cell lymphoma in the uterine...

Primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL LT) accounts for approximately 20% of all primary cutaneous B-cell lymphomas and tends to present as infiltrated nodules, tumors, and plaques on the legs in the elderly. Unlike other primary cutaneous large B-cell lymphomas, it has a poor prognosis and tends to require treatment with systemic chemotherapy. We present the case of ...

Abstract Background Primary Breast Lymphoma is a rare manifestation of extranodal non-Hodgkin lymphoma and accounts for less than 1% all breast malignancies. It defined by localized involvement the mammary tissue lymphomatous infiltrate in absence prior extramammary concomitant widespread disease. Case presentation A 46-year-old melanodermic woman was referred to our hospital due an extensive u...

Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of extranodal diffuse large B-cell lymphoma (DLBCL) characterized by selective growth of neoplastic cells within the vascular lumen. IVLBCL involves all types of organs and mostly is associated with poor prognosis, but patients with cutaneous variant have significantly better survival. In this article we report a case of 80-year-old...

primary pancreatic lymphoma is a rare extranodal manifestation of any histopathologic subtype of b cell non-hodgkin's lymphoma that predominantly involves the pancreas. it comprises less than 0.2% of pancreatic malignancies and less than 0.7% of non-hodgkin's lymphomas. this lymphoma is almost never suspected clinically. it is usually diagnosed by surgical exploration for suspected ad...

Primary cutaneous marginal zone lymphoma (MZL) is a common B-cell lymphoma of skin and is characterized by an infiltrate of neoplastic marginal zone B cells typically within the marginal zones of reactive lymphoid follicles and the interfollicular region. However, in our experience, many cases have underemphasized features such as marked plasmacytic differentiation and/or a prominent T-cell com...

Precursor B-cell lymphoblastic lymphoma (B-LBL) is an uncommon high-grade neoplasm of immature B cells. It occurs predominantly in childhood with extranodal involvement such as skin and bone. Therefore, primary cutaneous involvement in elderly adults is a very rare manifestation of B-LBL. Here, we report a 78-year-old man with B-LBL presenting as a single cutaneous lesion which was immunohistoc...

Primary cutaneous marginal zone B-cell lymphoma (MZL) is considered a cutaneous counterpart of extranodal MZL of mucosa-associated lymphoid tissue and an indolent lymphoma. Amyloid deposition in this tumor is very rare. We report here a case of primary cutaneous MZL with massive amyloid deposition. The tumor disseminated to the dura and mimicked primary dural MZL. The patient had a four year hi...
