A 23-year-old male presents with a lesion on his right upper lid. He says he first noticed the lesion approximately 6 weeks ago, at which time it was red and painful. Over the following weeks, the redness and pain subsided but he still has a visible nodule on the right upper lid. He reports no other complaints such as red eye, decreased vision, or diplopia. His past ocular and medical history is unremarkable.
On exam, a firm non-tender nodule is palpated deep in the right upper lid close to the lid margin. The lesion does not appear inflamed. The patient also has evidence of some mild blepharitis, with a small amount of thick white discharge expressed from glands with lid pressure.
