Thymic pathology findings. (A and B), IHC staining for CD5 (anti-CD5 antibody, ZA-0510, ZSGB-BIO, China) shows that several ectopic GCs can be found in the thymic cortex (A, ×4; B, ×20). (C and D), HE-stained images show fibrous tissue proliferation and infiltrated lymphocytes (C, ×1; D, ×10). The lymphocytes were mainly located in the peripheral region of fibrosing proliferation (black arrows)
