Difference of Histological findings between the areas with and without eosinophilic infiltration: a-c; Spindle neoplastic cells (a) were prone to present around no or scant eosinophilic infiltration area with fibrosis (b, Elastica Masson-Goldner stain) and D2–40-positive lymphatic vessel proliferation (c). d-f; Conversely, polygonal neoplastic cells (d) were prone to present around relative much eosinophilic infiltration area without evident fibrosis (e, Elastica Masson-Goldner stain) and D2–40-positive lymphatic vessel proliferation (f).
