title: Practical study of the correlation between the shape of tumoral vessels (Folberg) and the histologic type of uveal malignant melanoma (Callender).
abstract: A practical study was carried out on 20 cases of uveal malignant melanoma (UMM), dealing with the histological aspect (according to Callender's classification modified by McLean et al. in 1983) and the shape of the tumor vessels (according to Folberg 1992). A correlation was reported in the literature between the histopathological type of UMM and the vascular aspect. Folberg et al. (1992) reported that a correlation exists between the histopathologic type of UMM and the aspect of the vascularization. Folberg et al. (1992) reported that in spindle cell UMM parallel or normal vessels prevail: in epitheloidal shaped cell UMM arc- or ring-shaped vessels are prevalent; and in mixed MMU parallel, ring- and arc-shaped vessels and networks were noticed. The present study aimed at simplifying the correlation between the histopathologic type and vascularization in 5 categories with an easier applicability in the ophthalmologic practice.
