4Department of Pathology, Stanford University, Stanford, CA. xtranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, or MALT lymphoma, is a non-Hodgkin’s lymphoma associated with chronic inflammation. It typically occurs in the gastric mucosa or the thyroid parenchyma, and is rarely reported in the breast [1]. Histologically, MALT lymphoma is characterized by heterogeneous...

Primary breast lymphomas (PBL) are an exceptionally rare form of extranodal non-Hodgkin lymphoma (NHL), occurring in less than 0.5% all malignancies.1 T-cell (TCL) is even rarer entity, accounting for only 6% lymphomas. It has aggressive but poorly understood clinical course, and non-specific features that can mimic inflammatory carcinoma (oedema, skin changes mastalgia).1 Currently, there no s...

PRIMARY LYMPHOMA OF BREAST -UNUSUAL TYPE-A CASE REPORT (ABSTRACT): Introduction: Primary Lymphoma of the breast (PBL) is a rare entity, while secondary involvement of the breast with diffuse disease is more common. While Non Hodgkin Lymphoma type is the usual variant in PBL. We report a case primary Hodgkins lymphoma of the breast. Case Presentation: A 50 yr old woman presented three years ago ...

We report a case of primary breast lymphoma in a 75-year-old woman who noticed a lump in her right breast after trauma. Mammographic, ultrasonographic, and pathologic correlations are provided. The typical appearance of primary breast lymphoma on mammography is a solitary, uncalcified, circumscribed, or indistinctly marginated mass with adjacent lymphadenopathy. On ultrasound, primary breast ly...

Lymphoma is a rare neoplasm in the breast. In this location, it may be primary or secondary, depending on whether there is lymphoma elsewhere in the body. The most common presentation of breast lymphoma is a painless palpable mass, indistinguishable from that of breast carcinoma, although the treatment regimens for these two neoplasms differ vastly. Knowledge of the varied mammographic and sono...

We report on the development of an uncommon association of pathologic processes, where an invasive adenocarcinoma of the breast developed concomitantly with a primary lymphoma arising in the same breast. The patient, a 78 year old female, presented with two palpable breast lesions in her left breast and an additional lesion in the right breast. Core needle biopsies of the lesions revealed both ...

Primary Breast lymphoma is a rare lesion that has been reported in patients without HIV. However, Primary Breast lymphoma occurring in a patient with HIV has rarely been reported despite the fact that HIV infection is known to increase the propensity to develop certain types of lymphoma. We report a case of an HIV patient with breast lymphoma that was discovered by screening mammography while p...

Hematological malignancies rarely affect the breast, and the majority of those that do are lymphomas. In this review, we describe the clinical aspects and multimodal imaging findings of breast lymphoma. We also illustrate the key clinical and radiological findings that allow it to be distinguished from various other malignant and benign diseases of the breast. Breast lymphoma manifests as a bre...

SUMMARY Anaplastic large cell lymphoma of the breast is a rare malignancy associated with prosthetic breast implants. We present a case of a woman with no prior history of breast implants who developed anaplastic lymphoma kinase-1 negative anaplastic large cell lymphoma on a background of a previous benign cyst aspiration.

Primary lymphoma of the breast is a rare occurrence because of the paucity of lymphoid tissue in the breast and is an even rarer entity in the male breast. Imaging, along with tissue diagnosis goes a long way in diagnosing breast lymphoma which has a significantly different management scheme than other breast neoplasms with respect to radio-chemotherapy rather than surgical resection. We presen...
