A rarely described Kimura's disease of the breast

Kimura's disease is a rare chronic inflammatory disease of unknown aetiology. The majority of cases are reported in middle-aged Asian males and rarely seen in other ethnicities. Patients classically present with chronic single or multiple painless subcutaneous masses, lymphadenopathies, hypereosinophilia and elevated serum immunoglobulin E. The disease usually affects the head and neck area, however, rare involvement of other locations such as axilla, upper limbs, popliteal region and abdomen has been reported. Here, we report a rarely encountered Kimura's disease of the breast and axillary lymph nodes in a middle-aged female. In this report, we will describe the main clinical, radiological and pathological features to raise the awareness about this indolent disease.
