case_images: (a) Fundoscopy of the right eye showing a complete retinal detachment and a tumoral mass temporal-inferior-nasal. (b) Ultrasound of the right eye showing a 17 x 15 x 10.5 mm measuring tumoral mass with a positive kappa angle. (c) Biopsy of the right eye, using the Essen biopsy forceps. The specimen obtained measures 2 x 1 mm, and histopathological section shows a fragment of collagenous connective tissue permeated by melanophages and, separate from this, a loose grouping of atypical, polymorphic cells with acidophilic cytoplasm and large, irregular and hyperchromatic nuclei. (d) The histopathology of enucleation showing a 17 x 15 mm spindle cell choroid melanoma (pG1) with areas of ischemic necrosis.

case_images: Fundoscopy of the right eye showed a complete retinal detachment and a tumoral mass temporal-inferior-nasal (Figure 1(a)). Transpalpebral ultrasonography showed a 17 x 15 x 10.5 mm measuring mass with a positive kappa angle (Figure 1(b)). The specimen obtained measured 2 x 1 mm, and histopathological section showed a fragment of collagenous connective tissue permeated by melanophages and, separate from this, a loose grouping of atypical, polymorphic cells with acidophilic cytoplasm and large, irregular and hyperchromatic nuclei (Figure 1(c)). The histopathology of enucleation showed a 17 x 15 mm spindle cell choroid melanoma (pG1) with areas of ischemic necrosis (Figure 1(d)), and pathological staging was pT3a.

case_images: (a) Picture showing the new Essen biopsy forceps. (b) Biopsy of the right eye, using the Essen biopsy forceps. The specimen obtained measures 1 x 1 mm, and histopathological section shows a small fragment of neoplastic tissue formed by conglomeration of cells with acidophilic cytoplasm with poorly defined and atypical nuclei with dense chromatin, sometimes polarized. Some cells containing melanin pigment. (c) Histopathology of enucleation showing a 14 x 13 mm choroid melanoma with areas of recent hemorrhage.
