Paraurethral endometriosis is an extremely rare condition. To the best of our knowledge, only seven cases with details on variable risk factors have been reported in the English literature. Herein, we present the case of a third nulliparous patient described in the literature at the time of diagnosis. A 30-year-old woman presented with mild urinary symptoms. A well-defined 2.3 cm paraurethral cystic lesion was found on clinical examination, and MRI findings were suggestive of hemorrhagic content, with no evidence of pelvic endometriosis. Complete surgical excision was performed, and the patient's symptoms improved. The patient experienced no recurrence for 10 months postoperatively. The histopathological findings were suggestive of endometriosis. These findings might indicate that embryonic remnants are possible causes of the pathogenesis of paraurethral endometriosis.
