Supraclavicular lymph node metastases from distant primary tumors: Case reports and review of the literature

Cervical lymph nodes are a common site of metastases for malignant tumors, most commonly developed from head and neck primary tumors. But, they can also be secondary to distant primary tumors. We report the case of two patients treated in our Otorhinolaryngology and Head and Neck department for chronic supraclavicular lymphadenopathies, for whom further investigations showed lymph node metastasis originating from distant tumors. Thus, careful clinical examination, imaging tools, and if possible pathological analysis are necessary to establish an early diagnosis for adequate treatment.
