Parotid gland metastasis - an unusual presentation of adenocarcinoma of lung.

Lung cancer is the most frequent malignant disease and the most common cause of cancer death in the world. Primary carcinoma of the lung was an uncommon cancer until the 1930s. Common cell types in bronchial carcinoma are squamous 35%, Adenocarcinoma 30%, Small-cell 20%, Large-cell 15%. We present a case of a bronchial neoplasm metastasis to the parotid gland. A 50 years old male patient presented with a 7×5cm painless parotid mass that was metastatic adenocarcinoma on histopathology. Then we thoroughly examined the patient and he was investigated accordingly. There was an abnormal shadow in the lung on chest x-ray, CT revealed a lung tumour on left side. Metastasis to the parotid gland from any distant primary site is quite unusual. We are going to present this case in the journal because of its rarity. Parotid gland metastasis from the lung is rare & if a careful examination is not performed primary focus may be overlooked, negatively affecting the lifetime survival rate & the prognosis of the patient.
