Differential Diagnosis for Female with Right Side Neck Swelling and Lump on Roof of Mouth
Single Most Likely Diagnosis
- Torus Palatinus: A benign bony growth on the roof of the mouth, which can be asymptomatic or cause discomfort. The neck swelling could be related to a separate issue, such as a benign cyst or lymphadenopathy, but the combination of these symptoms, especially with a negative dental exam, points towards a benign condition like Torus Palatinus for the oral finding.
Other Likely Diagnoses
- Benign Neck Cyst (e.g., Branchial Cleft Cyst): These are congenital anomalies that can present as a lump in the neck, often on one side. They are usually asymptomatic but can become infected.
- Lymphadenopathy due to a Viral Infection: Although the patient does not have a fever, some viral infections can cause lymph node swelling without systemic symptoms.
- Dental Abscess or Infection not Detected on Initial Exam: Despite a negative dental exam, it's possible for a dental infection to cause both neck swelling (due to lymphadenopathy) and a lump on the roof of the mouth if the infection has spread.
Do Not Miss Diagnoses
- Malignancy (e.g., Oral Cancer, Lymphoma): Although less likely, any persistent swelling or lump, especially in the neck or oral cavity, necessitates consideration of malignancy. Early detection is crucial for treatment outcomes.
- Tuberculosis: Can cause lymphadenopathy and oral lesions, though it's less common. The lack of fever does not rule out TB, as it can present in a variety of ways.
- Sarcoidosis: A systemic disease that can cause lymphadenopathy and oral lesions, among other symptoms.
Rare Diagnoses
- Rhabdomyoma: A rare benign tumor of the muscle that could potentially occur in the oral cavity or neck.
- Castleman Disease: A rare disorder that involves an overgrowth of cells in the body's lymph nodes, which could cause neck swelling.
- Kimura Disease: A rare, chronic inflammatory disorder that can cause lymphadenopathy and eosinophilia, more commonly seen in Asian males but can occur in females and other populations.
