title: [Narrowing of the palpebral fissure as the first symptom of extensive osteoma with orbital involvement].
abstract: Unilateral narrowing of palpebral fissure and moderately impaired visual acuity induced a 14 years old woman to consult an ophthalmologist. Neuroradiological examination revealed a large osteoma starting from the ethmoid cells and invading both the orbit and the cranial cavity. This case illustrates that proptosis may be absent even in cases of extensive and compact orbital tumors. Therefore, exophthalmos is a common but not an indispensable sign of an orbital tumor. In Gardner's syndrome osteomas are associated with soft tissue tumors, intestinal polyposis and colonic adenomatosis that ultimately progresses to colorectal cancer. This association is frequent enough that a colon examination should be suggested to all patients with osteoma.
