[Spontaneous regression of epithelial thymic tumours].
BACKGROUND
Spontaneous regression of an epithelial thymic tumour has been reported but seems extremely rare. Its mechanism is unknown.


METHODS
We report two cases of epithelial thymic tumour, either histologically proven or highly suspected on imaging, that regressed spontaneously (partially in one patient and totally in the other).


CONCLUSIONS
Spontaneous regression of an epithelial thymic tumour is very rare but this possibility could lead to clinical and radiological monitoring rather than surgery in selected patients.
