62 Primary breast lymphoma: a report of 13 cases and revue of literature

Abstract

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.
