Uterine cervical adenomyoma: Case report and literature review.

RATIONALE: Cervical adenomyoma is a rare benign tumor that is easily confused with malignant diseases of the cervix, including malignant and benign cervical diseases. Misdiagnosis results in mistakes in therapy. This study aims to enhance the understanding of cervical adenomyoma through a case report, including clinical symptoms, physical examination, and surgical photos, at the same time a systematic review of cervical adenomyoma will be done, thereby helping to avoid clinical misdiagnosis.

PATIENT CONCERNS: A 39-year-old woman with a cervix mass about 3 × 3 cm. The root of the tumor was located in the cervical canal, and contact bleeding was positive. The pap smear and human papillomavirus test were normal. The menstrual cycle was normal. Ultrasonography revealed that the uterus and bilateral ovaries were normal. There is no relevant family history. Cervical hyperplasia or cervical myoma was considered before surgery.

DIAGNOSES: The patient was diagnosed with cervical adenomyoma.

INTERVENTIONS: Hysteroscopy was taken, and histopathology was taken after surgery.

OUTCOMES: Histopathology revealed that the lesions were mixed cervical glands with smooth muscles.

LESSONS: Through the case report, we gain a better understanding of the diagnosis of cervical adenomyoma. Histopathology and immunohistochemical staining were conducive to diagnose cervical adenomyoma. A review of existing literature helps distinguish it from other benign and malignant cervical tumors, thereby reducing misdiagnosis.
