A Rare Case of Submandibular Gland Metastasis as the First Sign of Adenocarcinoma of the Lung | Insight Medical Publishing

The current study document is an unusual case of submandibular metastasis as the first sign of adenocarcinoma of the lung. We report a 57-year-old male chronic smoker presented with a tumefaction in the submandibular gland. The patient had a complete excision. At the histological examination, the diagnosis of an undifferentiated carcinoma of the submandibular gland was retained. A systemic work-up was performed, which unexpectedly detected a tumor in the right lung and was confirmed by histopathological examination. Despite their rarity, submandibular lesions should be considered as possible manifestations of underlying malignancies.
