Definition / General
  • Not in WHO breast classification
  • Aggressive behavior despite small size and minimal nodal involvement
Terminology
  • Also called invasive ductal carcinoma with large central acellular zone, ring carcinoma, central necrotizing carcinoma
Clinical Features
Prognostic Factors
  • Poorer prognosis than matched patients with poorly differentiated tumors containing less extensive necrosis
Micro Description
  • Well circumscribed, solitary nodule with extensive central necrosis or collagen / hyaline deposition, constituting a majority of tumor volume, surrounded by a narrow rim of viable high grade tumor cells (ring-like hypercellular zone) with pushing border and minimal tubule formation
  • Relatively sharp margin but infiltrative growth accompanied by eosinophilic intercellular matrix
  • Abrupt transition between peripheral cellular and central acellular zones without alteration of cancer cell adhesion (Pathol Int 2009;59:390)
