BACKGROUND:

The mammary affectation by a lymphoma is not frequent; it almost always involves type B lymphomas. It is characterized by a lack of clinical and radiological specificity, which makes differential diagnosis difficult with mammary tumors of another origin.

CLINICAL CASE:

A 72-year-old patient with a history of hypercholesterolemia, hypertension, osteoarthritis and depression, with two deliveries and menopause at 55 years of age. Mother with a history of postmenopausal breast cancer. The mammography of the right breast reported the existence of a retroareolar mass of 8 cm, of ill-defined contours and an axillary adenopathy with cortical thickening. The biopsy reported a high-grade non-Hodgkin B lymphoma. 8 cycles of chemotherapy were administered with the R-CHOP scheme. After this procedure, the PET-CT showed a residual, metabolically inactive right mammary lesion, with nodal or extramammary supra or infradiaphragmatic disease.

CONCLUSIONS:

A malignant mammary neoplasm is not always a ductal or lobular carcinoma. It is necessary to evaluate the possibility of other histological strains or, even, of a metastatic affectation. The adequate interview and exploration are fundamental for a good diagnostic orientation.
