Introduction:
Spontaneous regression of an epithelial thymic tumour has been reported but seems extremely rare. Its mechanism is unknown.
Case Report:
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).
Conclusion:
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.
