Mondor disease, or superficial thrombophlebitis of the breast, is an uncommon 
disorder that occurs only rarely in pregnant women. One such case is presented 
here followed by a review of the clinicopathologic features of the disease. 
Accurate diagnosis of Mondor disease is based almost entirely on careful 
physical examination of the breast, and no specific treatment is required. Its 
major clinical significance lies in the need to distinguish it from malignancy 
of the breast.
