[Unilateral edema of the breast secondary to congestive heart failure. Report of 2 cases].

This report describes two cases of diffuse unilateral edema and skin thickening of the breast, that mimics an inflammatory carcinoma, caused by congestive heart failure. The clue to the correct diagnosis of congestive enlargement of the breast is the presence of 'pitting' edema, which is not found in malignant breast edema. Resolution of the breast enlargement usually occurs when the heart failure is properly treated.
