Synchronous Presentation of Ductal Carcinoma In Situ of the Breast with Follicular Lymphoma

ABSTRACT

A synchronous incidence of breast cancer and follicular lymphoma (FL) is uncommon. The association between these two conditions could be explained by the antigenic stimulation of the adjacent carcinoma and common genetic background. This study aimed to review the literature, and discuss the etiology and management of synchronous breast cancer and FL. Herein, we presented a case of synchronous ductal carcinoma in situ (DCIS) of the breast and FL involving multiple lymph nodes, including those in both axilla. A 49-year-old woman presented with palpable lumps in both axilla. She underwent lumpectomy, radiotherapy, and hormonal therapy for DCIS, while adjuvant chemotherapy was recommended for the lymphoma. Diagnosis was based on histopathologic analysis, such as excision or biopsy.
