Leiomyomatosis Peritonealis Disseminata Associated with Endometriosis and Multiple Uterus-Like Mass: Report of Two Cases

Leiomyomatosis peritonealis disseminate (LPD) is a rare benign disease of unknown etiology of women in reproductive age. A few reported cases of association with endometriosis have been described suggesting a possible origin from submesothelial multipotential cells. We present two cases of LPD associated with endometriosis expressing smooth muscle metaplasia, and some of the nodules with aspects of uterus-like mass. Laparoscopy, gross findings, and the pathological and immunohistochemical study of the surgical specimens were described. Our findings suggest an endometriotic origin for the LPD and indicate that the therapeutic approach might contemplate the surgical reduction of the nodules and endometriosis treatment

An increasing number of parasites are being added to the list of those that can be transmitted via food or water and that pose a risk to human health if ingested. These zoonotic infections usually have complicated life cycles requiring a number of hosts for completion or a diversity of cycles of transmission that may interact. The challenge in all control efforts is to break the cycle of transmission that may lead to human infection, which requires the ability to detect and characterize the relevant parasite life cycle stage in food or water. This requires tools that are both sensitive and specific, and often beyond the limitations of conventional techniques such as microscopy
