Ureter - an unusual site of breast cancer metastasis: A case report

Figure 1 Computed tomography urography scan showed a severe obstruction in the lower segment of the left ureter along with left hydronephrosis.

Figure 2 Hematoxylin and eosin-stained histological ureter section showing infiltration of poorly differentiated tumor cells that displayed an alveolar growth pattern (magnification, 100×).

Figure 3 Immunoreactivity in tumor cells. A: Weak nuclear immunoreactivity for estrogen receptor in tumor cells (magnification, 100×); B: Negative immunohistochemical staining for progestin receptor in tumor cells (magnification, 100×).
