## Correct Answer: D. Secondaries neck Hoarseness of voice in a 60-year-old with cervical lymphadenopathy points to **recurrent laryngeal nerve (RLN) involvement** by metastatic lymph nodes. The RLN, a branch of the vagus nerve, descends in the neck and passes through the larynx to innervate all intrinsic laryngeal muscles except the cricothyroid. Metastatic cervical lymphadenopathy (secondaries neck) commonly compresses or infiltrates the RLN, causing vocal cord paralysis and hoarseness. This is a classic presentation in Indian cancer patients with advanced malignancy (lung, gastric, breast, or thyroid primary) spreading to cervical nodes. The combination of hoarseness + palpable cervical lymph nodes in an elderly patient is highly suggestive of metastatic disease. Unlike benign causes (goiter, TB lymphadenitis), secondaries typically present acutely with systemic features and rapid progression. The examination likely showed firm, fixed, matted lymph nodes characteristic of malignancy rather than the mobile, rubbery nodes of TB or the diffuse swelling of goiter. ## Why the other options are wrong **A. Sternomastoid tumor** — Sternomastoid tumors (fibromatosis or rhabdomyosarcoma) are rare in elderly patients and typically present as a mass within the muscle itself, not as cervical lymphadenopathy. They do not cause hoarseness via RLN compression as a primary feature. This is a pediatric diagnosis, not a 60-year-old presentation. **B. TB lymphadenitis** — TB lymphadenitis presents with mobile, matted, rubbery lymph nodes that may suppurate and form sinuses—not the firm, fixed nodes of malignancy. While TB can cause hoarseness via laryngeal involvement, it is less common in elderly patients without prior TB exposure or immunosuppression. The acute presentation with RLN compression is more typical of metastatic disease. **C. Multinodular goiter** — Multinodular goiter causes hoarseness via compression of the RLN by the enlarged thyroid gland itself, not by cervical lymphadenopathy. The examination would show a diffuse thyroid enlargement, not discrete lymph nodes. Goiter is a chronic condition with gradual onset, whereas metastatic disease presents more acutely in an elderly patient. ## High-Yield Facts - **Recurrent laryngeal nerve (RLN) paralysis** is the mechanism of hoarseness in metastatic cervical lymphadenopathy; the nerve is compressed or infiltrated by malignant nodes. - **Secondaries neck** presents with firm, fixed, matted lymph nodes (>2 cm, hard, non-mobile) in contrast to TB (mobile, rubbery) or reactive nodes (soft, mobile). - **Common primaries** for cervical metastases in India: lung (most common), gastric, breast, thyroid, and nasopharyngeal cancers. - **Hoarseness + cervical lymphadenopathy** in a patient >50 years is metastatic disease until proven otherwise; requires urgent imaging (CT/MRI neck) and primary site search. - **Unilateral RLN paralysis** causes hoarseness; bilateral involvement causes stridor and airway compromise—a surgical emergency. ## Mnemonics **RLN Compression Causes (CHAMP)** **C**arcinoma (metastatic nodes), **H**yperplasia (goiter), **A**neurysm (aortic arch), **M**ediastinal mass, **P**ancreatic cancer. Use when differentiating hoarseness causes in elderly patients. **Malignant vs Benign Lymph Nodes (FIRM vs SOFT)** **F**irm, **I**mmobile, **R**ubbery-hard, **M**atted = Malignancy. **S**oft, **O**ver 2 cm, **F**luctuant, **T**ender = TB/Reactive. Quick bedside discrimination. ## NBE Trap NBE pairs hoarseness with thyroid pathology (goiter) to trap students who reflexively think "thyroid = voice change." However, the key discriminator is the presence of **cervical lymphadenopathy** (not thyroid enlargement) in an elderly patient—this shifts the diagnosis to metastatic disease with RLN involvement. ## Clinical Pearl In Indian tertiary centers, a 60-year-old with acute hoarseness + hard cervical nodes is metastatic disease until proven otherwise. Always examine for a primary (lung, gastric, breast) and order CT chest + neck. RLN paralysis is often the **presenting symptom** of advanced malignancy in India, where many cancers are diagnosed late. _Reference: Bailey & Love Ch. 38 (Neck); Harrison Ch. 97 (Approach to Cancer Patient); Robbins Ch. 7 (Neoplasia)_
