Post-coital bleeding: a rare and unusual presentation of cervical endometriosis

Often due to benign conditions such as cervical ectopy, post-coital bleeding is a distressing symptom for the patient. However, for the clinician, the identification of the etiology is important in order to effect proper treatment.

We present a case referred to the colposcopy clinic because of post-coital bleeding and a smear report of 'groups of benign glandular cells of endometrial origin'. Colposcopy was normal but histology of an excised haemorrhagic nodule revealed endometriosis with resolution of symptoms.

Cervical endometriosis should be considered in the differential diagnosis of post-coital bleeding with no obvious ectopy or malignancy.
