Gross examination

Gross appearance of invasive ductal carcinoma.

As per:

or mastectomy.

Microscopic evaluation

Invasive ductal carcinoma, with occasional entrapped normal ducts (arrow).

Malignant cells having penetrated the basement membrane.

Staging

TNM staging is the most common system for invasive carcinomas.[1]

For lymph nodes (N):[1]

  • Clusters <0.2mm can be called "isolated tumor cell clusters"
  • Clusters 0.2 - 2.0 mm: "Micrometastasis"
  • At least one carcinoma focus over 2.0 mm: "Metastasis". If one node qualifies as metastasis, count all other nodes even with smaller foci as metastases.

Critical numbers of involved nodes: 1-3, 4-9, and 10 and over. Note any extranodal extension.[1]

Grading

Further information: Evaluation of tumors

Report
