Case 3: low-grade follicular lymphoma and Langerhans cell sarcoma. This case shows a low-grade follicular lymphoma (A, H&E, 200× and B, H&E, 100×) in association with Langerhans cell sarcoma (B, H&E, 100× and D, H&E, 400×). A PU.1 immunohistochemical stain (C, 400×) demonstrates more intense expression in the Langerhans cell sarcoma than in the follicular lymphoma. The low-grade B-cell lymphoma was positive for CD20 (E, 200×) and BCL6 (F, 200×). H&E indicates hematoxylin and eosin.
