Hematometra Caused by Chronic Lichen Planus in a Patient Mimicking Acute Urinary Retention: A Case Report.

The association between lichen planus (LP) with subsequent hematometra and acute urinary retention (AUR) is quite rare, and few cases reported that association. In such cases, if the patient is left untreated, then possible kidney injury and bladder wall rupture may arise from that retention. In this case, we reported a patient who is known to have a background history of long-standing LP that presented with a history and features suggestive of AUR and was found to be caused by hematometra on an ultrasound scan.
