Differential Diagnosis for Burning in Mouth with White Coating

• Single Most Likely Diagnosis
  • Oral Thrush (Candidiasis): This is the most likely diagnosis due to the presence of a white coating in the mouth, which is a hallmark of oral thrush. The burning sensation can be attributed to the infection causing inflammation and irritation of the mucous membranes.
• Other Likely Diagnoses
  • Oral Lichen Planus: This condition can cause a burning sensation in the mouth and may present with white, lacy patches, although it's less likely to cause a distinct white coating.
  • Geographic Tongue: While it doesn't typically cause a white coating, it can lead to burning sensations and alterations in the tongue's surface, which might be confused with a coating.
  • Denture-Related Stomatitis: If the patient wears dentures, this condition could cause a burning sensation and might be associated with a white coating due to poor denture hygiene and candida overgrowth.
• Do Not Miss Diagnoses
  • Leukoplakia: Although less common, leukoplakia can present with white patches in the mouth and requires consideration due to its potential to progress to oral cancer. The burning sensation could be due to associated inflammation or the underlying pathology.
  • Lymphoma: Certain types of lymphoma can manifest in the oral cavity, causing a range of symptoms including burning sensations and alterations in oral mucosa, though a white coating is less typical.
• Rare Diagnoses
  • Pemphigus Vulgaris: An autoimmune disease that can cause blisters and erosions in the mouth, potentially leading to a burning sensation. While it might not typically present with a white coating, the erosions could be confused with such.
  • Sjögren's Syndrome: An autoimmune disorder that can cause dry mouth (xerostomia), leading to burning sensations. However, it's less likely to cause a white coating directly, though secondary infections could.
