A Synchronous undifferentiated nasopharyngeal carcinoma and infiltrating ductal carcinoma of the breast successfully treated with induction chemotherapy followed by local control of both tumours: a case report

BACKGROUND: Multiple primary cancers have a low incidence particularly when cancers are synchronous. Few cases of synchronous head and neck cancer and breast carcinoma are reported in the literature. CASE PRESENTATION: We report here an exceptional case of a 47 years old Moroccan woman presenting two synchronous cancers, the first in the nasopharynx and the second in the breast. The patient was treated successfully with a combined strategy associating chemotherapy, radiation therapy, and surgery. She remains disease free after 27 months of follow up. CONCLUSIONS: Treatment strategy in the case of multiple primary cancers remains controversial because of the variety of presentations; initial aggressive treatment reports good results.
