RESUMEN
PURPOSE: The aim of this study is to illustrate our personal experience concerning the diagnostic and therapeutic management of primary and secondary orbital melanomas. PATIENTS AND METHODS: Nine patients (five men and four women) with a histological diagnosis of orbital malignant melanoma were surgically treated in our department during the last 10 years (1995 - 2005). RESULTS: All the patients had a unilateral orbital malignant melanoma. A primary tumour was diagnosed in one case. There was metastatic orbital localisation of a cutaneous malignant melanoma in two cases. In six cases, a secondary melanoma originated from the uveal tract (three cases), conjunctiva (two cases), or paranasal sinuses (one case). All the patients underwent surgical treatment of the tumour (exenteration in 5 cases; subtotal exenteration in one case; subtotal excision in two cases; and craniofacial resection in one case) combined with immunotherapy in one case. The median age at surgery was 66 years, with a mean postoperative follow-up of 17 +/- 14 months. Four patients died of widespread dissemination of the melanoma after a mean time of 13 +/- 7 months. Two more patients died of causes other than melanoma. Three patients were still living at 9, 33 and 45 months after surgery. None of the patients presented with a local relapse of the melanoma during follow-up. CONCLUSION: Although different approaches have been proposed, the prognosis of orbital melanoma remains poor. In our experience too, the patients with longest survival were those whose tumours were exenterated.
