title: A freely movable mucosa-associated lymphoid tissue lymphoma in the preaponeurotic space.
abstract: A 70-year-old man presented with a painless, solitary mass in the left upper eyelid. The mass moved freely in the whole upper eyelid. MRI revealed a 15×10×5 mm sized, well-circumscribed mass in the space between the orbital septum and the levator aponeurosis. The tumor was removed en bloc via a skin crease approach with simultaneous bilateral ptosis repair. The immunohistopathological diagnosis was a mucosa-associated lymphoid tissue (MALT) lymphoma. This is the first case of a freely movable MALT lymphoma in the preaponeurotic space.
