EBV+ Mucocutaneous ulcer. The biopsy is from an elderly patient present with an oral mucosal ulcer. The top panel is a whole mount showing ulcerated oral mucosa and a deep lymphoid infiltrate. The section lower left shows a pleomorphic infiltrate including numerous large lymphoid cells that resemble a large cell lymphoma. The immunostain for EBV LMP1 is positive in the cytoplasm of the large cells (right). This patient was treated conservatively with resolution of the lesion. Hematoxylin and eosin, original × 40 (top) and × 240 (lower left). Immunostain for EBV LMP1 (right) with hematoxylin counterstain × 300.
