Vernix caseosa peritonitis: report of two cases with antenatal onset.
Maternal peritonitis secondary to fetal vernix caseosa is considered an infrequent complication of cesarean section in which commonly spilled amniotic fluid is incompletely lavaged. Nine of the 10 reported cases have been diagnosed in the postpartum period after an uneventful cesarean section. Characteristically, vernix elicits granulomatous inflammation, occasionally with a mass lesion simulating bowel perforation and leading to colectomy. One case of antenatal leakage of amniotic fluid has been reported, also with granulomatous inflammation. We report two additional cases of antenatal leakage, both with acute inflammation lacking granulomatous features or mass lesions. The interval between amniotic fluid contamination and histopathologic evaluation is the basis for variations in the inflammatory pattern.
