RESUMEN
Non-Hodgkin's lymphoma (NHL) of the breast may be primary or secondary. Both are rare and there are no morphological criteria to make the differential diagnosis. Benign intramammary lymph nodes are often encountered, but the development of either primary or secondary lymphoma within an intramammary lymph node is extremely rare. We report the case of a 72-year-old woman who presented with a palpable mass in her right breast. A mammography showed a large intramammary lymph node from which a biopsy was taken. On morphological and immunohistochemical examination the tumor fulfilled the criteria of NHL originating in an intramammary lymph node. The patient received chemotherapy which led to the disappearance of the mass. A review of the literature revealed that this is the third reported case of primary NHL originating in an intramammary lymph node.

Primary renal lymphoma is a rare disease. There is still no agreement on its development primarily in this non-lymphoid organ. Some of the reported cases are questionable because of the incomplete staging of extrarenal disease. In the present study, we describe a rare case of a 73-year-old white man presenting with right flank pain. Physical examination did not reveal any peripheral lymphadenopathy or hepatosplenomegaly. An abdominal computerized tomography (CT) showed a large tumor in the right kidney with no enlarged liver, spleen or lymph nodes. On morphological and immunohistochemical examination, the tumor fulfilled the criteria of anaplastic large cell lymphoma (ALCL). A review of the literature revealed that this is the first reported case of primary ALCL of the kidney.

Involvement of the gastrointestinal (GI) tract by multiple myeloma (MM) is extremely rare. The small intestine and stomach are the most frequent sites of spread. We report 1 case of a 61-year-old woman who presented with clinical and radiographic features of an acute large bowel pseudo-obstruction. An abdominal computerized tomography (CT) showed a large tumor of the rectum. On morphological and immunohistochemical examination the tumor fulfilled the criteria of MM. The patient received combined chemotherapy and radiotherapy which led to the disappearance of the tumor. A review of the literature revealed that this is the first reported case of MM presented as acute large bowel pseudo-obstruction due to a rectal myeloma tumor.
