Histological and immunohistochemical findings in T-cell lymphoblastic lymphoma of the testis. The tubules are separated by a proliferation of blue uniform cells with an interstitial pattern of growth, occasionally invading the lining epithelium (A-B). The neoplastic population expresses TdT (C) and CD2 (D) (A-B: H & E, C: TdT stain, D: CD2 stain; A: O.M., 5×; B, D: O.M., 20×; C: O.M., 40×).
