Background:
Vulvar cancer rarely sends metastases to distant sites.
Case:
A 49-year-old female presented with a vulvar mass. The histologic examination revealed an infiltrating lesion with free surgical margins and no evidence of lymph node involvement. Four months following surgery, due to a bloody breast discharge and a palpable breast lump an excisional biopsy was performed. The histological evaluation revealed morphological features suggestive of metastatic squamous cell carcinoma. The morphological, immunohistochemical and in situ hybridization findings were consistent with a breast metastatic nodule of squamous cell carcinoma arising from the primary vulvar cancer.
Conclusion:
We conclude that the specimens are from the same origin therefore making the breast lesion a metastasis from the vulva.

Metastasis
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
