Low-grade mucosa-associated lymphoma of the breast: radiological-pathological correlation

Primary breast lymphoma generally is a rare disease. We present a case of a low-grade mucosa-associated (MALT) lymphoma of the breast in a 32-year-old woman, a distinctive type of localized non-Hodgkin's lymphoma (NHL), which is very seldom located in the breast. We performed differential diagnosis and radiological-pathological correlation with regard to typical microscopic criteria and clinical relevance that apply for that special entity.
