II. Causes: Smooth Tumors - Reactive or Inflammatory
- 
                          Pyogenic Granuloma
                          - Single, fast growing, friable, Red Papules (most commonly on the lips or Gingival mucosa)
- May be pedunculated
 
- Irritation Fibroma- Single smooth dome shaped Papule, typically along the bite line
- Caused by chronic irritation of the Oral Mucosa
 
- Lingual Thyroid
III. Causes: Smooth Tumors - Salivary Gland
- 
                          Mucocele
                          - Mucous filled polyps that form on any of the mucosal surfaces
- Typically form on inner lower lip and inner cheek, but also may involve ventral Tongue
 
- 
                          Ranula
                          - Translucent mass alongside the frenulum
- Submaxillary gland or Sublingual Gland cyst due to duct obstruction
- Named for its appearance as a frog belly (Ranula = "little frog")
 
- Neoplasm- Pleomorphic adenoma
- Mucoepidermoid Carcinoma
- Adenoid Cystic Carcinoma
 
IV. Causes: Smooth Tumors - Mesenchymal
- Neurofibroma
- Schwannoma
- Lymphoma
V. Causes: Rough Tumors
- Tongue Squamous Cell Carcinoma
- 
                          Oral Squamous Papilloma (HPV 6, 11)- Single tumors most commonly on the ventral Tongue
- Lesions are typically smaller, and not clustered (unlike Condyloma acuminatum)
 
- Condyloma acuminatum (HPV 2, 6, 11, 16 or 18)- Single or multiple dome shaped lesions
- Localized to the dorsal Tongue and lingual frenulum
