Indolent Breast Lymphomas: A Case Series and Review of Literature

Indolent breast lymphomas (IBL) are a rare form of extranodal lymphoma. There are very few reported cases of IBL presenting as a breast mass. We report two cases of IBL, a Marginal Zone Lymphoma (MZL) and a Small Lymphocytic Lymphoma (SLL), which were discovered on routine mammogram and later confirmed by biopsy and flow cytometery. Patient with MZL underwent chemotherapy and radiation therapy whereas patient with SLL was treated with chemotherapy alone.
