Cystic adenoid carcinoma (CAK) is a rare malignant tumor primarily affecting the salivary glands, but it can also involve other sites, including the uterine cervix. This tumor is associated with a high potential for local recurrence and pulmonary metastasis. We present the case of a 73-year-old diabetic woman with a history of cervical adenocarcinoma treated with radiochemotherapy and total hysterectomy. She was hospitalized for acute dyspnea, and imaging revealed pulmonary lesions, which were confirmed by biopsy as pulmonary metastases of CAK. A review of the hysterectomy specimen revealed a mixed carcinoma with both adenoid cystic and squamous cell components. The patient was started on palliative chemotherapy. The diagnosis and management of mixed carcinomas of the uterine cervix, including CAK, remain complex and require a multimodal approach.
