Differential Diagnosis

• Single most likely diagnosis
  • Irritant contact dermatitis: This is the most likely diagnosis given the patient's history of using sanitizer on his gloves and then touching his skin, which would have caused irritation and a burning sensation.
• Other Likely diagnoses
  • Allergic contact dermatitis: The patient may have an allergic reaction to an ingredient in the sanitizer or moisturizer, which could cause a similar burning sensation and skin irritation.
  • Dry skin or eczema: The patient's use of moisturizer suggests that he may have dry skin, which could be exacerbated by the sanitizer and cause a burning sensation.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
  • Anaphylaxis: Although unlikely, anaphylaxis is a life-threatening condition that requires immediate attention. If the patient's symptoms worsen or he experiences difficulty breathing, anaphylaxis should be considered.
  • Chemical burn: Depending on the concentration and type of sanitizer used, a chemical burn is possible, especially if the patient experienced a severe burning sensation.
• Rare diagnoses
  • Photosensitive reaction: If the sanitizer contained photosensitizing agents, the patient may have experienced a photosensitive reaction, which could cause a burning sensation and skin irritation.
  • Neurological disorder: In rare cases, a neurological disorder such as trigeminal neuralgia could cause a burning sensation in the face or neck, although this would be unlikely given the patient's history of using sanitizer.
