Cervical aortic arch
Cervical aortic arch (CAA), a rare congenital anomaly first described by Reid in 1914, in which the aortic arch sits above the clavicles; often a pulsatile neck mass, classified by Haughton types A–E, treated surgically when symptomatic.
Cervical biopsy
A cervical biopsy is a procedure that samples tissue from the cervix to check for precancer or cancer, usually done during colposcopy after an abnormal screening result.
Cervical cancer
Cervical cancer, a malignant neoplasm of the cervix caused by persistent high-risk HPV (types 16 and 18 dominate), is the fourth most common cancer in women, with about 662,000 cases and 349,000 deaths in 2022, preventable by HPV vaccination and HPV-based screening.
Cervical cerclage
Cervical cerclage: surgical stitching of the cervix, also called cervical stitch, placed in the second trimester to prevent preterm birth from cervical insufficiency; transvaginal McDonald or transabdominal routes, removed around 37 weeks.
Cervical dermoid cyst
Cervical dermoid cyst (dermoid cyst of the neck), ORPHA:141046, a rare benign cyst with keratinized epithelium and skin appendages, usually a slow-growing submandibular or sublingual mass, diagnosed by imaging and treated by surgical excision.
