Elastoma of the Orbit: A Case Report.

A 78-year-old man presenting for revision ptosis surgery was found to have an asymptomatic left inferomedial orbital mass visible below the left lower eyelid on external inspection, and subconjunctivally on examination. This was subsequently diagnosed as an isolated elastoma. A mass in a similar location was excised 60 years previously. His other ophthalmological history included stable diplopia corrected with prism, left-sided ectropion, bilateral sequential phacoemulsification, and past bilateral ptosis which has been persistent on the left side despite surgical repair and revision. His examination revealed left hypertropia but was otherwise largely unremarkable. However, imaging demonstrated the soft tissue lesion abutting the left globe. An anterior orbitotomy was performed, and the lesion was biopsied and specimens sent for histopathological examination and immunohistochemistry. This is the first case of an elastoma of the orbit reported in the literature to the best of the authors' knowledge.
