ICD-11 2C74 — Malignant neoplasms of fallopian tube

Tumours of the fallopian tube are much less common than the corresponding ovarian neoplasms; however, histologically the same surface epithelial-stromal tumour subtypes are recognised. Sex cord-stromal and germ cell tumours are rare. Hydatidiform moles and gestational choriocarcinoma are uncommon complications of tubal ectopic pregnancy. The wolffian adnexal tumour is also infrequent and typically occurs in the leaves of the broad ligament. The risk factors appear similar to those of the ovary. Fallopian tube carcinomas are a component of the hereditary breast-ovarian cancer syndrome caused by BRCA1 and BRCA2 germline mutations.

The diagnosis includes nothing.

Diagnosis with code 2C74 contains 3 clarifying diagnoses:

1. 2C74.0 — Adenocarcinoma of fallopian tube
2. 2C74.Y — Other specified malignant neoplasms of fallopian tube
3. 2C74.Z — Malignant neoplasms of fallopian tube, unspecified
