Immunohistochemistry for IDO in mature T- and NK-cell neoplasms: Primary cutaneous CD8-positive aggressive epidermotrophic cytotoxic T-cell lymphoma (A,B), ×200, A: H&E stain. The tumor showed diffuse reactivity for IDO protein, score 4 (B). Enteropathy-associated T-cell lymphoma, type II (C,D), ×200, C: H&E stain. The tumor showed weak reactivity for IDO protein, score 0 (D). Angioimmunoblastic T-cell lymphoma(E), ×100; Insert: ×400. The tumor was scored 1 for IDO protein (E). Subcutaneous panniculitis-like T-cell lymphoma (F), ×100; Insert: ×400. The tumor showed diffuse reactivity for IDO protein, score 4 (F).
