Categories:
Benign mesonephroma (Wolffian tumors or Wolffian duct adenomas) 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.[1] Surgery is the recommended treatment. In a small number of cases, recurrences or malignancy have been been reported. Close follow-up is advised.[2]
