Core tip: The commonest type of simple vaginal cyst is the Mullerian cyst. These are typically lined by columnar epithelium and contain serous or mucinous fluid. If the cyst contains blood it is thought to be due to the presence of endometrial elements in the cyst wall. It is then termed an endometrial cyst. We describe a simple Mullerian vaginal cyst containing blood in which no endometrial tissue was found. No cause for the intracystic hemorrhage was identified. We conclude that intracystic hemorrhage can occur in a simple Mullerian vaginal cyst in the absence of endometrial components.
