Histological feature of Burkitt lymphoma. (a) A nodal lesion showed the architecture of lymph node was totally effaced (H&Ex40); (b) intestinal lesion showed tumor cells were diffusely infiltrated in the submucosa and also intruded into mucosa. (H&Ex40); (c) “starry sky” and “square off” pattern were obviously seen. (H&Ex400); (d) a nodal lesion displayed a more pleomorphic feature with prominent nucleoli resembling “immunoblast”. Abundant apoptosis and mitoses are present (H&Ex400)
