We report the case of a 53 year-old female patient with an orbital der
moid cyst. A mass effect with proptosis, hypotropia and choroidal fold
s was noted. Imaging aspects (radiography, ultrasonography and compute
d tomography) were highly suggestive of a deep orbital dermoid cyst. A
fronto-temporal neuro-surgical approach allowed complete removal of t
he tumour. Histopathology confirmed the diagnosis of dermoid cyst. The
incidence of orbital dermoid cyst falls significantly after the secon
d decade of life thus making our clinical case original.
