Three cases of ceroid granulomas of the female genital system are pres
ented, involving the cervix in two and lesions in the ovaries and bowe
l serosa in the other. Ceroid granulomas are unusual and interesting l
esions formed when suitable substrates accumulate within macrophages t
o such an extent that a relative lack of biological antioxidants resul
ts and auto-oxidation and conversion to ceroid is favoured. This may o
ccur in the setting of haemorrhage and necrosis, whether fi om tumour
necrosis or associated with endometriosis. Other sources of lipids and
lipoproteins include bile, meconium and vernix caseosa.
