Kimura’s Disease: A Rare Case Presentation of a Subcutaneous Breast Lesion in an Asian Woman

Abstract

We report a case of a 54 year old Asian woman referred to our hospital for a subcutaneous right breast swelling for the last one year. No other systemic symptoms were present and a mild hypereosinophilia was found in routine blood tests .To rule out any neoplastic lesion and reach a specific diagnosis, Excision biopsy of the lesion under local anaesthesia was performed, Histopathological examination showed lymphoid infiltrates with prominent reactive germinal centres along with infiltration by eosinophils and vascular proliferation, a diagnosis of Kimura’s disease of breast was made. The patient was put on symptomatic treatment and clinical follow up revealed complete regression of the swelling and disease. This case has been reported due to its extreme rarity and highlights the need for including Kimura’s disease in the differential diagnosis of subcutaneous breast swellings. Knowledge of Kimura’s disease, its clinical appearance, course and histopathology puts the clinician in a better position to diagnose.  Long-term follow-up should be mandatory for Kimura’s disease.
