Abstract
Leiomyomas are the most common benign uterine neoplasms of the myometrium. Rarely, can be observed unusual manifestations of these tumours.
We present a case of intravenous leiomyomatosis in a 52-year-old woman and a case of benign metastasizing leiomyoma in a 45-year-old woman. Intravenous leiomyomatosis is an uncommon condition in which morphologically benign smooth muscle is present within the lumina of the veins.
Benign metastasizing leiomyoma is a very rare phenomenon where histologically benign smooth muscle tumours are present at distant sites, particularly in the lungs, in women having histologically benign uterine leiomyoma. The diagnostic features, etiology, histology, therapeutic management and prognosis of these extremely rare conditions are discussed.
