Leiomyomatosis peritonealis disseminata (LPD) are multiple nodules adherent to and superficially invading the peritoneum,mimicking metastatic ovarian carcinoma. Their origin would be metaplastic mesenchymal cells (MC), which in susceptible women MC could originate from surgical myoma fragments [1]. Estrogen may stimulate subcoelomic MC to proliferate, differentiating into myoblasts, myofibroblasts, fibroblasts, and even decidua-like cells [2]. LPD can express sex steroid receptors, hence be promoted by hormonal stimulation, e.g., pregnancy or exogenous intake [3]. LPD is rare (
