purpose: to describe a case of endometrial carcinoma with an atypical outcome. material and methods: we report a typical early endometrial adenocarcinoma with a good prognosis, which after a long latent period showed an atypical outcome with the appearance of a lung tumour suspicious to be another primary tumour. however, a good response was obtained treating with carboplatin and paclitaxel, known as an active chemotherapy of endometrial neoplasms. discussion: early endometrial tumours have survival rates between 80 and 90%. it is unusual the development of progression after a long disease-free period.
