Adenoid cystic carcinoma(ACC)is a rare malignant epithelial tumor originating from salivary gland tissue.The occurrence of ACC in the cervix is even rarer,representing for only 1%of all cervical adenocarcinomas.It is highly invasive,has a poor prognosis,and lacks a standard treatment plan.This article reports the diagnosis and treatment of a patient with cervical ACC combined with basal cell carcinoma and squamous cell carcinoma.The patient,an elderly woman,was admitted to the hospital for a newly discovered mass at the vaginal opening accompanied by intermittent vaginal bleeding.The pathological biopsy results of the vaginal mass showed malignant tumors,consistent with ACC;she underwent laparoscopic pelvic lymph node dissection+total hysterectomy+high ovarian arteriovenous ligation(bilateral)+bilateral ovarian and fallopian tube resection+intestinal adhesion lysis+mesenteric neoplasm resection.Postoperative pathology showed cervix mixed cancer composed of ACC,adenoid basal cell carcinoma and squamous cell carcinoma,along with local non-specific spindle cell sarcomatoid stroma.She received two cycles of chemotherapy and one session of radiotherapy postoperatively;the patient recovered well after surgery,and no metastasis or recurrence was found in regular follow-up examinations until January 22,2024.
