“…Usually, the neoplasm presents itself as a large unilateral and painless mass, rarely bilateral, and with an average size of 3 cm 9,10 . Considering the clinical characteristics, the patient remains in accordance with the literature, being asymptomatic, including without presenting the classic B symptoms -systemic symptoms of fever, night sweat, and unexplained loss of more than 10% of weight in six months -, being the tumor identified as an incidental finding in imaging tests 1,9,10 .…”

A 42-year-old woman, with no history of autoimmune diseases or risk factors for cancer, sought a private medical clinic for undergoing breast imaging tests, noticing the presence of a solid nodule with indistinct margins — BI-RADS 4 — in the left breast. An ultrasound-guided core biopsy was performed and complemented by histopathological and immunohistochemical studies, confirming the diagnosis of primary small B-cell MALT lymphoma. After treatment with radiotherapy, the patient evolved with remission, maintaining annual follow-up with a specialist physician. The importance of routine screening for pathologies that affect the breasts is highlighted, aiming at their early diagnosis. In addition, radiotherapy has good prognostic results at the expense of surgical treatment.

“…MALT lymphomas involving the breast are rare—<0.5% of all breast malignancies—because of the scarcity of mucosa associated lymphoid tissue in the breast. Breast MALT lymphoma is reported in 1.7%–2.2% of extranodal breast lymphoma 4. In our case, MALT lymphoma coexisted in breast and submandibular and parotid glands.…”

Breast MALT lymphoma and AL amyloidosis complicating Sjögren’s syndrome

Marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphomas of the breast with mammary amyloidosis are exceedingly rare entities. This report describes the case of women with long-standing Sjögren’s syndrome presenting with breast MALT lymphoma and amyloïd light-chain (AL) amyloidosis. Breast microcalcification needle biopsy made the positive diagnosis. This unusual finding should be kept in mind. It emphasises the need for careful clinical examination of nodes and extranodal organs supposedly affected in patients with autoimmune disease.

“…The worldwide incidence of SS is difficult to assess as many cases remain undiagnosed for years [ 12 , 13 ]. Overall, extranodal MALT lymphomas more frequently affect the stomach, spleen, thyroid, ocular adnexal tissues, and salivary glands, while they are rare in the breast (1.7–2.2% of primary breast lymphomas), possibly due to the anecdotic presence of MALT tissue at this site [ 14 , 15 ].…”

The association between autoimmune diseases, mostly rheumatoid arthritis, systemic lupus erythematosus, celiac disease and Sjögren syndrome, and lymphoma, has been widely demonstrated by several epidemiologic studies. By a mechanism which has not yet been entirely elucidated, chronic activation/stimulation of the immune system, along with the administration of specific treatments, may lead to the onset of different types of lymphoma in such patients. Specifically, patients affected by Sjögren syndrome may develop lymphomas many years after the original diagnosis. Several epidemiologic, hematologic, and histological features may anticipate the progression from Sjögren syndrome into lymphoma but, to the best of our knowledge, a definite pathogenetic mechanism for such progression is still missing. In fact, while the association between Sjögren syndrome and non-Hodgkin lymphoma, mostly extranodal marginal zone lymphomas and, less often, diffuse large B-cell, is well established, many other variables, such as time of onset, gender predilection, sites of occurrence, subtype of lymphoma, and predictive factors, still remain unclear. We report on a rare case of primary breast lymphoma occurring three years after the diagnosis of Sjögren syndrome in a 57-year-old patient. The diagnostic work-up, including radiograms, core needle biopsy, and histological examination, is discussed, along with emerging data from the recent literature, thus highlighting the usefulness of breast surveillance in Sjögren syndrome patients.
