The image shows a rounded elevation that looks like it may contain some fluid and is located on the lower lip.
- A mucocele is a benign, mucus-containing cystic lesion of the minor salivary gland. It can appear with any minor salivary glands, but the most common location is the lower lip.
- A ranula is also mucus-containing cystic lesion but is related to the sublingual and submandibular salivary glands. For this reason, the swelling appears under the tongue.
- An ulcer can appear on any movable part of the oral mucosa in response to trauma. The lesion is usually yellow with red borders and is flat (not elevated).
- Exostosis is the overgrowth of normal compact bone on the buccal aspect of the maxilla or mandible.
Answer: (B). Mucocele
It is always important to associate our knowledge about oral pathology with their clinical appearance for the dental hygiene board exam (NBDHE, NDHCE, CSCE) because the case studies may have photographs. In this case, the location (lower lip) was the most important clue to the answer.
StudentRDH made a quick 5-minute video explaining about “why mucocele/ranula form and how they are different” available on our YouTube Channel. Please share it with friends too so everybody can score on questions related to this topic! Also if you are taking the CSCE Dental Hygiene Board Exam, pay attention x 100000!
