Clinical and pathologic features of invasive micropapillary carcinoma

Abstract
Invasive micropapillary carcinoma (IMC) of the breast is a rare subtype of breast carcinoma that has an extremely high incidence of lymph node metastases and poor clinical outcome. This histological subtype of breast carcinoma has remained unclear due to the rarity of cases. Many questions exist on the clinicopathological significance of this subtype, especially regarding prognosis.
