Differential Diagnosis for Fowl Taste in Mouth with Canker Sore and Swelling
- Single Most Likely Diagnosis
- Oral candidiasis (thrush) or other oral infections: The combination of a fowl taste in the mouth, canker sores, and swelling could be indicative of an oral infection. Oral candidiasis is a common condition that can cause these symptoms, especially in individuals with compromised immune systems or those who wear dentures.
- Other Likely Diagnoses
- Gingivitis or periodontitis: Inflammation of the gums (gingivitis) or the tissues surrounding the teeth (periodontitis) can lead to swelling, bad taste, and canker sores.
- Aphthous ulcers: These are recurring canker sores that can cause pain and swelling, potentially leading to a bad taste in the mouth.
- Dental abscess: A bacterial infection of the tooth or gums can cause swelling, pain, and a foul taste.
- Do Not Miss Diagnoses
- Oral cancer: Although less common, oral cancer can present with non-healing ulcers, swelling, and changes in taste. It is crucial to rule out this diagnosis due to its severe implications.
- Sjögren's syndrome: An autoimmune disorder that can cause dry mouth, leading to a foul taste and increased risk of oral infections and canker sores.
- HIV/AIDS: Individuals with HIV/AIDS are more prone to oral infections and conditions, including oral candidiasis, which can cause the described symptoms.
- Rare Diagnoses
- Pemphigus vulgaris: A rare autoimmune disease that can cause blistering of the skin and mucous membranes, including the mouth, leading to swelling and a foul taste.
- Eosinophilic ulcer: A rare condition characterized by an ulcerative lesion in the mouth, which can be painful and cause a bad taste.
- Wegener's granulomatosis (Granulomatosis with Polyangiitis): A rare autoimmune disorder that can affect various parts of the body, including the mouth, causing ulcers and a foul taste.
