Breast Carcinoma with Choriocarcinomatous Differentiation: A Rare Case
Objectives: Breast carcinoma with choriocarcinomatous differentiation is a rare entity, generally presenting with high-grade disease and an aggressive clinicalcourse with overall survival of less than a year
Case: A 69-year-old woman with a diagnosis of pT1N0M0 invasive ductal carcinoma with choriocarcinomatous differentiation received six cycles ofadjuvant chemotherapy and is still disease free on the 23rd month after diagnosis, showing a better prognosis than most other cases reported in theliterature.
Conclusion: The reason for the poor prognosis for this type of breast carcinoma remains unclear. Standard chemotherapeutic agents administered for breastcarcinoma may be used for choriocarcinomatous differentiation.
