Figure 1. Histological findings on biopsy (our previous study [5]). (A) Histological appearance of left axillary lymph node with hematoxylin and eosin stain. Many lymphoid follicles with unclear atrophic germinal centers and expansion of interfollicular zone were apparent. Original magnification ×100. (B) A peripheral mantle layer was developed with a concentric cellular distribution. Original magnification ×200. (D) Arborized blood vessels were present and we noted infiltration of small lymphocytes and plasma cells in the interfollicular zone. Original magnification ×400. (C) Increase in megakaryocytes of the bone marrow was evident by hematoxylin and eosin stain. Original magnification ×200. (D) Silver impregnation stain confirmed an increase in reticular fibers. Original magnification ×400.
