Primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of B-Cell origin. The association of anaplastic lymphoma kinase (ALK) negative anaplastic large cell lymphoma (ALCL), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

we present 16 years old girl with primary breast lymphoma involving the both breasts simultaneously and co-incidence of central nervous system (cns) involvement which originated from the breast, in addition to evidence of lymphoma in multi-organ such as skin, mediastinum and some abdominal viscera. bilaterality has been observed in some series, but reports are few and series are often very smal...

Mantle cell lymphoma (MCL) is a subtype of non-Hodgkin's lymphoma (NHL) comprising around 7% of adult NHL. It is characterized by a chromosomal translocation t(11:14) and overexpression of Cyclin D1. The incidence of secondary gastrointestinal tract involvement in MCL ranges from 10 to 28% in various series. However primary gastrointestinal MCL is very rare, accounting for only 1 to 4% of prima...

the gastrointestinal tract is the most frequently involved extranodal location for malt* lymphomas, but malt lymphomas of the large intestine are rarely observed. a treatment for colorectal malt lymphoma has not yet been established. in colonic malt lymphomas, the literature suggests that surgical resection of localized lesion may be the best choice. in the present case, combination of multi-ag...

Medullary carcinoma (MC) of the colon and rectum is a rare entity, accounting for less than 0.1% of colonic adenocarcinoma that poses a diagnostic challenge for the practicing pathologist. Poorly differentiated or undifferentiated MC with an unusual histological appearance and immunoprofile in addition to heavy lymphoid infiltrate could make it problematic when differentiating it from a high gr...

A case of primary malignant non-Hodgkin's lymphoma of the breast is reported. This is the first well-documented case of breast lymphoma in our institution and also in Iran. The diagnosis of primary breast lymphoma requires the presence of lymphomatous infiltration in close ass, tissue in patients with neither previous lymphoma nor concurrent lymphoma in another site. There is no definite cl...

  Primary Hepatic Lymphoma (PHL) is rare and possibly associated with viral hepatitis and autoimmune diseases. Scleroderma could exceptionally be complicated by lymphoma. We describe PHL occurring in a 52-year-old female suffering scleroderma for eight years, with no history of cytotoxic or high-dose glucocorticoid therapy. CT scan, performed to work-up abdominal discomfort, constipation, and ...

primary adrenal lymphoma is extremely rare. we report a case with primary bilateral adrenal lym-phoma in a young male patient. he presented with abdominal pain and weight loss. pathologic study revealed malignant lymphoma, diffuse large cell type (t- cell origin). patient recieved combination chemotherapy and radiation therapy but 22 months after diagnosis died because of progression of dis ease
