Bronchorrhea revealing cervix adenocarcinoma metastastic to the lung

Copious bronchorrhea can be related to bronchioloalveolar carcinoma, but reports of bronchorrhea related to lung metastasis are rare. We report the case of a woman presenting lung metastases of a cervical adenocarcinoma revealed by bronchorrhea, eventually identified as ectopic cervical mucus. Treatment included anticancer drugs and erythromycin, the latter in order to reduce the bronchorrhea, with eventually poor efficacy. This observation illustrates the importance of respiratory signs in the post-therapeutic follow up of cancer, especially cough and bronchorrhea in adenocarcinoma.
