Leiomyomatosis peritonealis disseminata in a postmenopausal woman.

Leiomyomatosis peritonealis disseminata (LPD), a multifocal proliferation of smooth muscle like cells, has so far been described in 48 cases. Most of them were pregnant women or women taking the oral contraceptives, which supported the hypothesis that LPD is associated with hyperestrogenism. We report a 65-year-old women, without history of taking exogenous estrogens, which suggests that factors other than hormonal influences may contribute to pathogenesis of LPD.
