fallopian tube serous adenofibroma (MONDO_0003461, a Monarch Disease Ontology term) is a rare, benign, asymptomatic neoplasm that arises from the fallopian tube. The majority of cases are incidental findings during operation for an unrelated gynecologic disorder. The tumors are round and solitary and contain connective tissue and papillary or tubular structures lined by serous-type epithelium. Also known as: fallopian tube adenofibroma, serous adenofibroma of fallopian tube.
