Recurrent eosinophilic mastitis.
Systemic diseases rarely present with manifestations in the breast. Disorders such as sarcoidosis and pyoderma gangrenosum have been described to produce signs and symptoms in the breast. Peripheral eosinophilia is a systemic disease associated with a finite group of conditions including asthma, allergic or atopic disease, collagen vascular disease, and parasitic infection. In addition it has been described in association with several malignancies. A 50-year-old woman with a history of asthma and significant eosinophilia presented with an enlarging breast mass. Complete excision of the mass revealed eosinophilic mastitis. Two years later the patient again presented with a large mass in the same breast. Repeat excision demonstrated the same pathology. The clinical significance of this lesion is important because it presents as an enlarging, painless, dominant mass. Excision is necessary for management and to conclusively rule out malignancy. Its recurrence despite excision to negative margins, however, may indicate that control of the eosinophilia--and possibly the underlying disorder--is important to prevent further recurrence.
