Introduction:
The cervix is a rare site of metastasis from advanced lung adenocarcinoma. Driven gene detection is particularly important for the treatment of advanced lung adenocarcinoma.
Patient Concerns:
A 49-year-old Chinese female was sent to our hospital because of lumbago and sacroiliac joint pain; she was unable to walk and had vaginal bleeding. The following examinations were performed: imaging, colposcopy, bronchoscopy, immunohistochemistry and next-generation sequencing.
Diagnosis:
According to the clinical manifestations and the examination results, the diagnosis was lung adenocarcinoma with cervical, brain, adrenal gland and bone metastases. More importantly, EGFR gene mutations (del19) were detected in both the primary lung lesion and uterine cervical biopsy specimen.
Interventions:
Osimertinib was chosen as the first-line treatment.
Outcomes:
Lumbago and sacroiliac joint pain were significantly relieved. The levels of tumor markers decreased. Primary injuries and metastatic sites were significantly reduced.
Conclusion:
Physicians should be alert to the signals of vaginal bleeding and consider that primary lung adenocarcinoma may metastasize to the uterine cervix.
