Question

A 23-year-old male presents with pain and swelling in the floor of the mouth, which worsens during meals. Radiographic examination shows a radiopaque mass in the submandibular salivary duct. What is the most likely diagnosis?

• A. Antrolithiasis
• B. Rhinolithiasis
• C. Sialolithiasis
• D. Sialometaplasia

Hint:

Pain and swelling during meals is a classic sign of salivary duct obstruction due to sialolithiasis.

Answer 1

The Correct Option is C

Step 1: Identify key clinical symptoms.
The patient has pain and swelling in the floor of the mouth that worsens during mealsThis is a classic sign of salivary duct obstruction because salivary flow increases during eating
Step 2: Correlate with radiographic findings.
A radiopaque mass in the submandibular duct strongly suggests a calcified structureThe submandibular gland is most commonly affected due to its long, tortuous duct and thicker saliva
Step 3: Evaluate the options.
(A) Antrolithiasis: Refers to a stone in the maxillary sinusNot related to salivary duct
(B) Rhinolithiasis: Refers to a calcified mass in the nasal cavityNot associated with salivary gland symptoms
(C) Sialolithiasis: Formation of a salivary stone in the ductCauses pain and swelling during mealsMatches both clinical and radiographic findings
(D) Sialometaplasia: Refers to necrotizing sialometaplasiaA benign inflammatory conditionNot associated with radiopaque ductal stones
Step 4: Conclusion.
Pain during meals combined with a radiopaque mass in the submandibular duct confirms sialolithiasis
