Özet

Uveal melanoma is the most common primary intraocular malignancy in adults. Several cytogenetic studies on uveal melanoma cells have revealed that the majority of these cells harbor alterations in chromosomes 3, 6, and 8. This report describes the results of cytogenetic analysis performed on a fresh choroidal melanoma tissue sample from a patient with cerebellar metastasis. Monosomy 7 mosaicism was observed. To our knowledge, monosomy 7 has not been reported in patients with uveal melanoma. We suggest that observation of monosomy 7 may be related to an aggressive clinical behavior and unusual cerebellar metastasis in uveal melanoma. Further data are necessary to define the exact role of monosomy 7 in the pathogenesis and evolution of uveal melanoma. (c) 2007 Elsevier Inc. All rights reserved.
