Unusual site of metastasis of bronchogenic carcinoma.

Metastasis of bronchogenic carcinoma to the chest wall and axillary lymphnodes is a rare occurrence. This study reports the case of a patient presenting with chest wall swelling as initial symptom which on evaluation was found to be a lymphnode metastasis. The patient also had axillary lymphnode metastasis on the same side as the chest swelling with a contralateral pleural effusion. Here, we discuss the pathways and possible mechanisms of contra lateral axillary and chest wall lymphnode involvement without ispilateral nodal involvement in bronchogenic carcinoma.
