True lateral dermoid cyst of the neck.

Area of Science:

• Head and Neck Surgery
• Diagnostic Imaging
• Dermatology

Background:

• Dermoid cysts are congenital tumors that can occur anywhere in the body.
• Lateral neck masses can present diagnostic challenges.
• Submandibular triangle masses require careful evaluation.

Observation:

• A case of a lateral dermoid cyst in the submandibular triangle is presented.
• The cyst did not exhibit any prior intra-oral swelling.
• Sonography was utilized for diagnostic purposes.

Findings:

• Sonography was instrumental in diagnosing the lateral dermoid cyst.
• The imaging findings were crucial for identifying the nature of the mass.
• This case highlights a less common presentation of dermoid cysts.

Implications:

• Sonography should be considered the primary imaging modality for submandibular triangle masses.
• Early sonographic diagnosis can guide appropriate surgical or medical management.
• Understanding rare presentations of dermoid cysts improves clinical awareness and diagnostic accuracy.
