Authors:  Fei Teng, M.M., Dong Chen, M.D., Ying Wu, M.D., Jian-feng Shang, M.M., Yan-wei Li, M.M., and Guo-liang Lian, B.M.
  Objective: To gain further understanding of the pathological features and biological behavior of solid papillary carcinoma (SPC) of the breast.
Study Design:
We stained tissue sections of a right atrial tumor excised from a patient with SPC of the breast with metastasis to the right atrium, using hematoxylin and eosin (H&E) staining and immunohistochemistry.
The solid area of the tumor showed an intermingled fibrovascular network with no apparent papillary structures on H&E staining, providing an auxiliary diagnosis for myocardial invasion. Immunohistochemical staining confirmed cardiac metastasis of invasive SPC of the breast.
Pathological examination of this case improves our understanding of the diagnosis and treatment of metastatic SPC.
