Resumen

ROLDAN-VALADEZ, Ernesto et al. Secondary non-Hodgkin's B-cell lymphoma involving the breast: radiologic imaging. Gac. Méd. Méx [online]. 2005, vol.141, n.1, pp.63-67. ISSN 0016-3813.

Secondary lymphomas involving the breast, although uncommon, represent the largest group of metastasic tumors to the breast. Primary non-Hodgkin lymphomas (NHLs) of the breast are also rare, accounting for 1.7% to 2.2% of extranodal NHL cases and 0.38 to 0.7% of all NHLs. Approximately 300 cases have been reported in the Medical literature. Mammographic appearances are described as round or oval areas of opacity. The breast mass may appear homogeneous or inhomogeneous. The lesion may be very well defined and may be mistaken for a benign process, most notable in patients younger than 35 years of age. Ultrasonographic appearance is described as a sharply defined mass with low or medium echoes. The posterior aspect of the mass is well defined (possibly with slight acoustic enhancement but with no associated posterior shadowing). In summary, the mammographic appearance of the breast lymphoma is nonspecific, but the diagnosis can possibly be excluded if calcifications or a desmoplastic reaction are present. Prominent lymph vessels in a patient with a breast mass should raise the suspicion of breast lymphoma. The most critical aspect in the workup of a breast mass is the tissue biopsy, since radiographically lymphomatous lesions are indeterminate. We present the case of a 79-year-old woman with abdominal pain and a palpable breast mass; we also make a brief summary of the clinical features and main imaging findings of NHL (plain radiograph, mammography, breast ultrasound and thorax tomography).
