Differential Diagnosis for 3 yo F with Rhinorrhea and Conjunctivitis
- Single Most Likely Diagnosis
- Allergic rhinitis with allergic conjunctivitis: This is the most likely diagnosis given the common presentation of rhinorrhea and conjunctivitis in a 3-year-old, which can be triggered by allergens such as pollen, dust, or pet dander.
- Other Likely Diagnoses
- Viral upper respiratory infection (common cold): This is a common cause of rhinorrhea and can be accompanied by conjunctivitis, especially in children.
- Bacterial conjunctivitis: Although less common than viral conjunctivitis, bacterial conjunctivitis can present with purulent discharge and can be accompanied by rhinorrhea.
- Adenoviral conjunctivitis: This is a highly contagious form of conjunctivitis that can cause significant discomfort and is often accompanied by rhinorrhea.
- Do Not Miss Diagnoses
- Gonococcal conjunctivitis: Although rare, gonococcal conjunctivitis is a serious condition that requires prompt treatment to prevent complications such as vision loss.
- Chlamydial conjunctivitis: Similar to gonococcal conjunctivitis, chlamydial conjunctivitis is a serious condition that requires prompt treatment.
- Kawasaki disease: This is a rare condition that can present with conjunctivitis, rhinorrhea, and other symptoms such as fever and rash, and requires prompt treatment to prevent cardiac complications.
- Rare Diagnoses
- Sjögren's syndrome: This is a rare autoimmune disorder that can cause conjunctivitis and rhinorrhea, but is unlikely in a 3-year-old.
- Sarcoidosis: This is a rare condition that can cause conjunctivitis and rhinorrhea, but is unlikely in a 3-year-old.
- Wegener's granulomatosis: This is a rare condition that can cause conjunctivitis and rhinorrhea, but is unlikely in a 3-year-old.
