Chest wall metastasis in squamous cell carcinoma of buccal mucosa

摘要

Metastases from head and neck cancers is rare occurrence. The common form of failure/recurrence in these cancers are local site recurrence or nodal metastases. Distant metastases are very rare and are most commonly seen in the lung, brain, liver and bones, and the latent period between the development of the primary and the distant metastases is usually long. There are very few cases reported of chest wall metastases from squamous cell carcinoma of head and neck. This article reports such a case of squamous cell carcinoma of buccal mucosa metastasizing to the chest wall four months after primary therapy. The metastasis was treated with local palliative radiotherapy to the chest wall. This case is special as the present knowledge on this type of presentation is limited in the medical literature.
