How are you? Vaginal leiomyomas are indeed rare and can be asymptomatic or present with symptoms, such as dyspareunia, pain, or dysuria. These are estrogen-dependent tumors and can grow rapidly during pregnancy and regress after menopause. Imaging studies such as MRI and CT scan help estimate the extent of the mass and its possible adjacent involvement. Surgery has generally been the treatment of choice fro this type of tumor. It is best that you have this checked by your gynecologist for proper evaluation. Take care and do keep us posted.
