Histopathologic characteristics of the conjunctival myeloid sarcoma. A Hematoxylin and eosin (H&E) stained section revealed a population of pleomorphic cells, a few with angulated nuclei and scant cytoplasm (H&E, × 400); B Immunohistochemical staining of myeloperoxidase (MPO) shows focal positivity (brown), suggesting the presence of myeloblasts (MPO, × 100)
