[Chlamydia trachomatis and cervix dysplasia]. / Chlamydia trachomatis y displasia cervical.

Fifty patients between 18 and 70 years of age from Gynecology and Obstetrics Department, Hospital General "Gonzalo Castañeda" ISSSTE, were studied. Patients were referred for bearing positive cytology with mild, moderate and severe dysplasia; also intentional search for Chlamydia trachomatis was made, both in cytology as well as with the immunofluorescence method, and also directed biopsy. A positive association was found in 10 patients (20%) proving that Chlamydia trachomatis is a promotor and modifier of cervical atypia.

[Disseminated peritoneal leiomyomatosis with malignant degeneration. A case report]. / Leiomiomatosis peritoneal diseminada con degeneración maligna. Informe de un caso.

Leiomyomatosis peritonealis disseminata (LPD), is a rare condition of unknown cause, characterized by the development of numerous nodules throughout the peritoneal cavity which appear during reproductive age, especially with pregnancy or associated with prolonged exposure to oral contraceptive agents. Histologically the nodules have the appearance of benign leiomyomata. LPD is thought to have originated from metaplasia of submesothelial multipotential mesenchymal cells. The treatment of the this disorder has been surgical castration, presumably to remove the hormonal stimulus necessary for tumor growth. Only two cases of malignant leiomyomatosis peritonealis disseminata have been reported. We report one more case of LPD with malignant degeneration which appears to be extremely rare.
