Histopathological features of pediatric follicular lymphoma.

(A) Low-grade tumor with large, focally coalescent nodular architecture. (B) Higher-power magnification of a case with predominantly intermediate-grade cytologic features. A grade 3 diffuse component was focally present in the tumor. (C) One case with floral variant morphology was composed predominantly of centroblasts, some of which had cleaved-cell morphology. (D) High-grade tumor with brisk mitotic rate and frequent apoptotic cells. Original magnification A, × 10; B-D, × 400. All images were stained with hematoxylin and eosin.
