Carcinosarcoma is a tumour with a malignant epithelial component (carcinoma) and a malignant mesenchymal component (sarcoma), based on the histomorphology.

They can arise in a number of sites:

Relation of carcinosarcoma to metaplastic carcinoma and sarcomatoid carcinoma

Carcinosarcoma implies that the tumour arose from mesenchymal cells and epithelial cells simultaneously.

This is in contradistinction to:

  1. Sarcomatoid carcinoma - implies the tumour arose from epithelial cells only and is sarcoma-like (morphologically), and
  2. Metaplastic carcinoma - implies the tumour arose from epithelial cells that had undergone a (morphologic) transformation (metaplasia).

Uterine carcinosarcomas are generally considered metaplastic carcinomas.[1][2] They typically metastasize as carcinomas,[3] and putatively arise from epithelial cells (only).

The term carcinosarcoma is from the morphologic era of pathology;[citation needed] it precedes the modern battery of molecular tests and immunohistochemistry.
