title: Early CT-scan for chronic lacrimal duct symptoms - case report of a malignant melanoma of the lacrimal sac and review of the literature.
abstract: Malignant melanoma of the lacrimal sac is rare, and only 21 cases have been reported in the world literature. They have an insidious onset and may look like chronic dacryocystitis. In only 6 of these cases were there no recurrences. In most of the survivors, the diagnosis was made early which appears to be the most important prognostic factor. Hence a CT-scan in cases of persistent dacryocystitis is important. Melanoma of the lacrimal duct system is a good example of a condition requiring a multidisciplinary approach between ophthalmologist and maxillofacial surgeon. Any persistently symptomatic lacrimal duct system may need a maxillofacial consultation.
