Study Notes
Diseases of Oral Cavity & Esophagus
- Oral cavity infections frequently involve herpes simplex virus (HSV-1).
- Common orofacial herpes manifestations are mild cold sores.
- Acute herpetic gingivostomatitis presents with vesicles and ulcers in the oral cavity.
- Recurrent herpetic stomatitis is a recurring condition.
- Apthous ulcers are common, superficial, and painful ulcerations of oral mucosa.
- These sores tend to heal on their own but can recur.
- Glossitis typically features a beefy-red tongue, resulting from vitamin B12 or iron deficiency.
- Oral candidiasis (thrush) shows superficial white patches or a fluffy membrane.
- This is caused by the fungus Candida, commonly found in the oral cavity.
- Conditions like diabetes, immunocompromised states (e.g., HIV), and neutropenia increase the risk.
Oral Manifestations of Systemic Disease
- Hairy leukoplakia appears as white, fluffy thickenings on the tongue's sides, frequently in immunocompromised individuals (especially those with HIV).
- Epstein-Barr virus is often associated with this.
- Infections like measles (Koplik spots), infectious mononucleosis, and diphtheria can manifest in the oral cavity.
- Dermatologic conditions like lichen planus, pemphigus, or erythema multiforme (including Stevens-Johnson syndrome) sometimes show oral manifestations.
- Hematologic disorders such as pancytopenia and leukemia can cause oral infections and lesions that resemble those seen in pancytopenia.
- Monocytic leukemia can cause infiltration and enlargement of the gingivae.
Precancerous Lesions
- Oral leukoplakia is a clinical term for white lesions that cannot be scraped off.
- It's classified as precancerous unless proven otherwise.
- Erythroplakia are less common, red, velvety lesions that can be more ominous and are linked to a higher risk of oral cancer.
- Tobacco use (cigarettes, pipes, cigars, chewing tobacco) is a significant risk factor for both leukoplakia and erythroplakia, particularly for the latter.
Tumors and Precancerous Lesions
- Other tumors, such as papillomas, hemangiomas, and lymphomas, can also occur in the oral cavity, although less frequently and often not linked to precancerous conditions.
- The most significant oral tumor is often squamous cell carcinoma (SCC).
- SCC lesions develop frequently in areas of the mouth like the floor of the mouth, tongue, hard palate, and base of tongue.
- Oral SCC often manifest as ulcerated or infiltrating lesions.
Oral Cavity Squamous Cell Carcinoma
- Smoking, tobacco, alcohol, and environmental elements often increase the risk of oral squamous cell carcinoma (OSCC).
- OSCC spread to cervical, mediastinal lymph nodes, lungs, and liver.
- OSCC is often classified according to the stage of dysplasia (mild, moderate, severe, or carcinoma in situ [CIS]) and the stage of invasion.
Odontogenic Tumors
- Odontogenic tumors are an assorted group of lesions classified according to origin (epithelial or ectomesenchymal or both).
- They can be benign, malignant, or hamartomas.
- The major groups include ameloblastoma, odontoma, odontogenic fibroma, odontogenic myxoma, and cementoblastoma.
Diseases of Salivary Glands
- Inflammations (siallinen), like mumps and autoimmune disorders like Sjogren's syndrome, typically affect the parotid gland.
- Sialolithiasis (stones) can block salivary ducts.
- Common benign tumors include pleomorphic adenomas (frequently seen in the parotid gland).
- Other benign tumors (such as Warthin tumor) include epithelial and mesenchymal elements, with mixed appearance.
- Malignant tumors, such as mucoepidermoid carcinomas and adenoid cystic carcinomas are observed in salivary glands.
Diseases of Esophagus
- Dysphagia, heartburn, pain, and hematemesis are common symptoms of esophageal diseases.
- Congenital anomalies, infections, chemicals, motor function alterations, and varices can affect the esophagus.
- Barrett's esophagus is an issue related to chronic gastroesophageal reflux (GERD) and subsequent esophageal changes.
- There is a connection to adenocarcinoma, a type of esophageal cancer.
- The esophageal squamous cell carcinoma is a common issue with various stages of involvement.
