A 50-year-old male patient having a history of chronic smoking presents with a single lymph node enlargement and hoarseness of voice. The next line of management is:
First, I need to consider the differential diagnoses. Chronic smoking is a major risk factor for head and neck cancers, especially laryngeal and lung cancers. Hoarseness can be due to vocal cord involvement or nerve damage. A single lymph node enlargement might suggest metastasis from a primary tumor in the head and neck region.
The next step in management would likely involve confirming the presence of malignancy. A fine needle aspiration cytology (FNAC) of the lymph node could help determine if it's malignant. If the node is suspicious, a biopsy would be necessary. Alternatively, imaging like a CT scan might be used to look for primary tumors, especially in the larynx or lung.
Hoarseness in a smoker could also be due to laryngeal cancer, so endoscopy (like laryngoscopy) might be needed to visualize the larynx. If the primary is suspected in the lung, a bronchoscopy could be useful.
The options given aren't listed, but the correct answer is likely to be a diagnostic test to confirm the cause. Since the question mentions a single lymph node and hoarseness, the priority is to check for cancer. So, the next step would be a biopsy or imaging to find the primary site.
Wait, the correct answer in the example given was C. So, if the options were like A) CT scan, B) MRI, C) Biopsy, D) Bronchoscopy, then C would be the correct answer because biopsy confirms the diagnosis. But without the actual options, I need to be careful. However, in similar cases, the standard next step after suspicious lymph node is a biopsy. So, the explanation would focus on the need for histopathological confirmation.
**Core Concept**
Chronic smoking increases the risk of head and neck malignancies, including laryngeal cancer. Hoarseness and a single enlarged lymph node suggest possible metastatic lymphadenopathy from a primary tumor. The priority is to confirm malignancy and identify the primary site.
**Why the Correct Answer is Right**
The next step is **biopsy of the lymph node** (e.g., excisional biopsy or core needle biopsy) to obtain histopathological confirmation of malignancy. Hoarseness may indicate vocal cord involvement or recurrent laryngeal nerve compression, but a biopsy definitively identifies the pathology. If malignancy is confirmed, staging imaging (CT/MRI) and endoscopic evaluation (laryngoscopy) follow to locate the primary tumor.
**Why Each Wrong Option is Incorrect**
**Option A:** *CT scan* is useful for staging but not diagnostic for lymph node pathology.
**Option B:** *MRI* is less commonly first-line for lymph node evaluation compared to biopsy.
**Option D:** *Bronchoscopy* is indicated if lung cancer is suspected but requires prior suspicion from imaging or biopsy.
**Clinical Pearl**
Never skip histopathological confirmation in a smoker with unexplained lymphadenopathy and hoarseness. "Single node plus hoarseness" is a classic red flag for head and neck cancer.
**Correct Answer: C. Biopsy
