A 30-year-old woman presents with bilateral painless upper lid swelling of 6 months duration, with downward globe displacement and ptosis worsening on upgaze. There is no proptosis. Which diagnosis is most likely?
- A Pleomorphic adenoma of the lacrimal gland ✓
- B Dacryoadenitis
- C Dermoid cyst
- D Lacrimal gland prolapse
Correct answer: A. Pleomorphic adenoma of the lacrimal gland
Explanation
Pleomorphic adenoma of the lacrimal gland presents as a slow-growing, painless superotemporal orbital mass causing downward and nasal globe displacement, ptosis, and fullness of the upper lid. It typically presents in the third to fourth decade. Dacryoadenitis is painful with acute inflammatory signs. Dermoid cyst presents in childhood as a superotemporal mass, often fixed to the periosteum at the frontozygomatic suture. Lacrimal gland prolapse is bilateral and reducible, not a true mass.
