Your Question

I've had a recurrence of a wolffian tumor. Is there a way I can talk to other women with this condition. Also, is there any research studies enrolling women with this tumor?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

What are wolffian tumors?

Wolffian tumors are rare tumors located anywhere along the length between the ovary and vagina in sites of remnant wolffian ducts. Wolffian ducts are structures in a developing embryo that get incorporated into the reproductive system in males and degenerate in females. Wolffian tumors are thought to have a low potential to become cancerous and tend to range from 0.8 to 25 centimeters in size. It is not clear what causes these rare tumors.[1]
