The absence of mitosis with nuclear atypism in all histological samples opens the question of whether the origin of the tumor in the lung was from uterine leiomyomas metastasizing or multifocal amarthomas, synchronous or metachronous. Hamartomas or real metastasis of uterine leiomyomas? The response to GnRH analogue treatment was evaluated.
