Lipoma - Oral Mucosal Lesion
Patients notice a soft, painless, slow-growing swelling in the mouth.
Some fatty tumors of the buccal mucosa are not true lipomas but rather herniation of the buccal fat pad, especially during or after surgery in the area.
D17.9 – Benign lipomatous neoplasm, unspecified
93163002 – Lipoma
Differential Diagnosis & Pitfalls
- Oral lymphoepithelial cysts – These tend to occur on the posterior ventral tongue, floor of mouth and in Waldeyer's ring (palate and oropharynx).
- Dermoid and epidermoid cysts –These tend to occur in the floor of mouth, often in the midline, in younger patients, and are generally doughier in consistency, and larger.
- Hyperplastic lymphoid/tonsillar tissue – This occurs in sites where lymphoid tissue is normally found such as Waldeyer's ring.
- Hyperplastic sebaceous glands (Fordyce spots) – These are generally not nodular, but rather papular and small.
- Granular cell tumor of the tongue – This is in the deep mucosa and presents as a firm mucosal mass rather than a sessile nodule.
