Representative pathological images of thymoma patients with FBs. FBs dividing tumors into different‐sized irregular islands were thick enough to be observed at low magnification (×1.25). FBs contained small amounts of fibroblasts and lymphocytes but rarely contained tumor cells. Hyalinosis was observed (×10). (a) Type A thymoma (×1.25); (b) type AB thymoma (×1.25); (c) type B1 thymoma (×1.25); (d) type B2 thymoma (×1.25); (e) type B3 thymoma (×1.25); (f) type A thymoma (×10); (g) type AB thymoma (×10); (h) type B1 thymoma (×10); (i) type B2 thymoma (×10); (j) type B3 thymoma (×10). FBs, fibrous bands.
