title: Histologic manifestations of perinatal genital mycoplasmal infection.
abstract: Genital mycoplasmas are controversial gynecologic and obstetric pathogens; their role in perinatal morbidity and mortality is ill defined. This retrospective study was conducted to identify autopsy manifestations of perinatal genital mycoplasmal infection. Bacterial and mycoplasmal cultures were obtained from multiple organ sites, along with detailed clinical, autopsy, and histologic information. All materials were screened by two pathologists. Twenty-nine cases were included in the study. In 17 only a genital mycoplasma was isolated, and in 12 cases a genital mycoplasma plus another bacterial pathogen were identified. Significant histologic findings included subpericardial and pleural hemorrhages, polymorphonuclear leukocytes in alveolar spaces, hemorrhage, and tubulocytic changes in the adrenal glands. The placentas revealed villous edema, deciduitis, and funicitis. The changes identified as significant suggest that mycoplasmas either cause hypoxia or promote histologic changes that mimick hypoxia.
