Abstract
Invasive carcinomatous lesions associated with borderline phyllodes tumors are extremely rare.
Molecular biological mechanisms associated with this kind of lesions are unknown.
PIK3CA gene mutation could be implicated in the development of these lesions.
Introduction
Carcinomatous lesions associated with phyllodes tumors are extremely rare and are found in less than 1% of all cases. To date, the molecular biological mechanisms associated with this carcinomatous transformation remain unknown.
Presentation of case
We present here the case of a 61-year-old patient with invasive ductal of no special type (NST) carcinoma originating in a borderline phyllode tumor with mutation in the PIK3CA gene.
Discussion
To the best of our knowledge, this mutation has never been described in this type of association.
Conclusion
Based on these data, we can better understand the ethiopathogenic molecular mechanisms in this type of lesion. Consequently, they could also in the future give rise to new therapeutic alternatives.
