Leiomyomas in patients receiving Tamoxifen.

: In literature there have been only 8 cases of unavoidable laparotomy due to uterine leiomyomas performed in patients with breast cancer on Tamoxifen (TAM). Our article describes two cases of rapidly growing leiomyomas in patients treated with TAM: one of these underwent abdominal hysterectomy while the second stopped taking TAM and began therapy with Triptorelin. This therapeutical alternative could be a useful choice.
