Resource summary
Soft tissue lesions of Oral mucosa
Hyperplasia
Fibroepithelial polyp
= fibrous tissue lump
Normal epithelium
Keratosis
Cause = chronic trauma
Fibrous epulis
Epulis
Vascular epulis
Giant cell epulis
Peripheral giant cell granuloma
= lesion of giant cells + RBCs/blood products outside vessels
Purple/red due to blood products outside vessels
Most common = anterior to 6s
= swelling on gingiva
Peduncle attachment
Easy surgical removal
Pyogenic granuloma
= lobular capillary haemangioma
Thin epithelium with overgrowth of blood vessels
Red appearance due to blood vessels
Yellow appearance due to ulcer slough
Peduncle attachment
Easy surgical removal
Vascular epulis
Can be pregnancy-related with poor OH
Denture granuloma
Basically = fibroepithelial polp caused by chronic trauma from denture
Leaf fibroma
Paillary hyperplasia of palate
Mucocele
= swelling filled with saliva
Most common = lower lip
If seen on upper lip -> more likely adenoma
Types
Mucus extravagation cyst
Redder lesion as saliva burst out tissues
Mucus retention cyst
Red border, centrally blue as saliva retained within ducts
Cause = trauma to minor salivary glands/ducts
Management
Leave to burst if small
Surgical removal if large
May re-occur
Lingual tonsil hyperplasia
Hyperplastic lymphoid tissue
Sore throat
Neoplasia
Benign
Squamous cell papilloma
Most common = lip & soft palate
Cause = HPV (some cases), idiopathic
White due to keratosis
Easy to surgically remove
Haemangioma
= neoplasm of blood vessels
Blanches on pressure then refills
Purple
Less common than hamartoma
Lymphangioma
= neoplasm of lymph vessels
Covered with normal mucosa
Less common than hamartoma
Bubbles on tongue surface
Lipoma
= neoplasm of fat
Soft & squidgy
Salivary gland tumour
Pleomorphic adenoma = most common
Neurofibroma
= neoplasm of peripheral nerves/Schwann cells
Granular cell tumour
Most common = dorsum of tongue
Flesh-coloured, under epithelium
Single lump/lesion
Malignant
Carcinoma
Squamous cell
Most common (9/10)
Presentation
Ulcerated
Rock hard
Granular surface
Rolled edge
Fixed to underlying tissue
Adenocarcinoma
Melanoma
Most common = palate
Brown/black lesion
Lymphoma
Rubbery
= malignancy of lymphocytes
Sarcoma
= connective tissue malignancy
Fibrosarcoma, lipsarcoma, osteosarcoma
Karposi's sarcoma = angiosarcoma
Metastases
Most common = breast, prostate, lung
Traumatic neuroma
Cause = damage to peripheral nerves
seen in skin post-parotid gland surgery or with lingual nerve damage
= non-neoplastic overgrowth of nerve fibres
