Histopathology of placentas from index and subsequent pregnancies in women with chronic histiocytic intervillositis (CHI).

	Index CHI	1st subsequent pregnancy	2nd subsequent pregnancy
N placentas	34	30	12
N placentas with pathology reports	34 (100%)	23 (76.7%)	8 (66.7%)
CHI	34 (100%)	11 (47.8%)	2 (25.0%)
Chronic villitis	5 (14.7%)	6 (26.1%)	2 (25.0%)
Increased fibrin deposition	18 (52.9%)	7 (30.4%)	2 (25.0%)
Small for gestational age	7 (20.6%)	4 (17.4%)	1 (12.5%)

Index pregnancy was defined as a participant's first pregnancy diagnosed with CHI by placental histopathological examination following poor outcome. Subsequent pregnancies refer to those following diagnosis. Variables are expressed as N (percentage).
