• An 18-year-old woman with malignant teratoid medulloepithelioma had an epibulbar, brown-black mass associated with expulsive hemorrhage and a limboscleral perforation. Histopathologically, a prominent pigmented neuroepithelial component was present and correlated to the black color of the mass. The massive hemorrhage is apparently related to rupture of necrotic and abnormal vascular channels within the angiomatous component of the neoplasm. Other mesenchymal elements included spindle-shaped cells, rhabdomyoblasts, and islands of hyaline cartilage.
