Differential Diagnosis for Growing Oral Plaque on the Tongue
Single Most Likely Diagnosis
- Oral Thrush (Candidiasis): This is the most likely diagnosis due to the description of a growing oral plaque on the tongue, which is a common presentation of oral thrush. The burning sensation can also be attributed to the infection.
Other Likely Diagnoses
- Oral Lichen Planus: This condition can cause white patches or plaques on the tongue and mucous membranes, and may be accompanied by a burning sensation.
- Leukoplakia: A condition characterized by white patches or plaques on the mucous membranes, which can be caused by chronic irritation or other factors.
- Oral Hairy Leukoplakia: A condition that causes white patches on the tongue, often associated with immunocompromised states, such as HIV/AIDS.
Do Not Miss Diagnoses
- Squamous Cell Carcinoma: Although less likely, it is crucial to rule out oral cancer, as it can present with similar symptoms, including a growing plaque or lesion on the tongue.
- Lymphoma: Certain types of lymphoma can manifest in the oral cavity, and a thorough evaluation is necessary to exclude this possibility.
Rare Diagnoses
- Pemphigus Vulgaris: A rare autoimmune disorder that can cause blisters and erosions on the mucous membranes, including the tongue.
- Oral Pseudomembranous Candidiasis: A rare condition characterized by the formation of a pseudomembrane on the oral mucosa, which can be associated with a burning sensation.
- Histoplasmosis: A rare fungal infection that can cause oral lesions, including plaques or ulcers on the tongue.
