Plasmablastic lymphoma in the orbit: case report.
Plasmablastic lymphoma (PBL) is a rare entity most commonly identified in the oral cavity of immunodeficient patients. The immunophenotype of this condition shows a poor expression for B-cell markers but, in contrast, a strong reactivity for well-differentiated plasma cells markers, such as CD138, CD38, and epithelial membrane antigens. PBL survival is limited due to its highly aggressive local and metastatic behavior and poor response to treatment. Although it can involve different organs, there have been only a few cases involving the ocular adnexa. We describe a case of atypical rapidly progressive pre-septal brawny induration affecting the right orbit in a patient with HIV-related lymphoma.
