A rare, benign, asymptomatic neoplasm that arises from the fallopian tube. The tumors are round and solitary and contain connective tissue and cystic structures lined by serous-type epithelium. The majority of cases are incidental findings during operation for an unrelated gynecologic disorder. The disease is fallopian tube cystadenofibroma (MONDO_0004501). Also known as: cystadenofibroma of fallopian tube, fallopian tube serous cystadenofibroma.
