In an elderly man with persistent hoarseness and painful ulcer at the floor of the mouth, what is the most likely suspicion?

• A. Oral thrush
• B. Squamous cell carcinoma of the head and neck
• C. Gastric reflux disease
• D. Salivary gland infection

Answer: (B)

In the scenario described, an elderly man exhibiting persistent hoarseness and a painful ulcer at the floor of the mouth raises strong suspicion for squamous cell carcinoma of the head and neck. This type of cancer is particularly relevant in this demographic due to risk factors such as advancing age, tobacco use, and alcohol consumption, which are common contributors to head and neck malignancies.

Persistent hoarseness, especially when combined with a non-healing ulcer, is a hallmark sign of potential malignancy in the upper aerodigestive tract. The ulcer in the floor of the mouth, along with hoarseness, points to possible invasion or irritation of surrounding structures, which can be indicative of a neoplastic process.

Other options, while they may have overlapping symptoms, do not fit the clinical presentation as closely. Oral thrush typically presents with white plaques in the mouth, not ulcers, and is more common in immunocompromised individuals. Gastric reflux disease may cause hoarseness but does not typically present with oral ulcers. A salivary gland infection might cause pain and swelling but is less likely to be associated with persistent hoarseness or a floor of mouth ulcer.

Thus, the combination of persistent hoarseness and a painful ulcer at the
