Introduction To retrospectively evaluate the epidemiological, clinical, imaging findings, and therapeutic features of breast lymphomas in patients who had primary lymphoma of the breast.
Materials and Methods This is a retrospective study including 13 patients with primary non-Hodgkin’s lymphoma of the breast treated at the institute Salah Azaiez from 2000 to 2019. This sample includes 1 case of follicular lymphoma, 2 cases of large T-cell lymphoma, and 10 cases of large B-cell lymphoma.
Results All the patients were women and aged between 17–89 years (average age: 52.6 years). The mean symptom was a breast lump, only one patient consulted for inflammatory signs in the breast. The average clinical size of the tumor was 7.2 cm, with a maximum of 15 cm.
Mammography showed an oval mass with circumscribed margins in the majority of cases. Ultrasound showed in most of the cases a hypoechoic irregular mass or multilobulated mass with irregular margin and hypervascular on color Doppler. Magnetic resonance imaging (MRI) was performed in only three patients and showed a spiculated lesion with polycyclic limits. 8 patients underwent surgery. In our study lymphoma involved 10 cases of large B-cell lymphoma, one case of follicular lymphoma, and two cases of large T-cell lymphoma. 11 patients had localized stages (I + II) at diagnosis, and 2 patients had the disseminated stage (stage III) of primary breast lymphoma. Seven patients underwent chemotherapy treatment alone, and five had chemotherapy with radiotherapy. The median follow-up of our patients was 53 months, ranging from 1 to 177 months. Overall survival was 71% at 3 years and 51% at 5 years.
