Key result
A 40-year-old woman was diagnosed with Kimura disease of the breast, presenting clinically as carcinoma, representing the first documented case of this entity in the breast.
Case Report (n=1)
This case report documents the first known instance of Kimura disease occurring in the breast, highlighting it as a potential diagnostic mimic of breast carcinoma.
Breast KD may mimic carcinoma; hypothesis-generating for expanded differentials in eosinophilic masses.
Kimura disease (KD) is a rare chronic inflammatory disorder of unknown etiology, primarily seen in young Asian males. The disease is characterized by a triad of painless subcutaneous masses in the head and neck region, blood and tissue eosinophilia, and elevated serum immunoglobulin E levels. We report an unusual case of a 40-year-old woman found to have KD of the breast which presented clinically as carcinoma, leading to a diagnostic dilemma. To the best of our knowledge, this is the first case of KD in the breast to be documented in the literature. The patient also had scabies, which may have provided the stimulus for hypersensitivity, which is considered to be the pathogenetic mechanism responsible for development of KD.
