cervical lymphadenopathy
Enlargement of lymph nodes in the neck region. May be reactive, inflammatory, or neoplastic in head and neck oncology contexts.
Full Definition
Abnormal enlargement of lymph nodes located in the cervical region, which can be caused by various pathologic processes including infection, inflammation, autoimmune disorders, or malignancy. In head and neck oncology, cervical lymphadenopathy is of particular concern as it may represent metastatic spread from primary head and neck cancers or primary lymphoid malignancies such as lymphoma. The pattern, size, consistency, and mobility of enlarged nodes provide important diagnostic clues. Nodes larger than 1 cm in diameter are generally considered abnormal in adults. Hard, fixed, non-tender nodes are more suggestive of malignancy, while soft, mobile, tender nodes often indicate reactive or inflammatory processes. Proper evaluation includes careful palpation, imaging studies, and often tissue sampling for definitive diagnosis.
Usage
Usage note: Specify the cervical level and laterality when documenting findings.
