case_images: Histologic evaluation from biopsies of the cardia mass demonstrated dense submucosal aggregates, composed of large cells, with lobated nuclear contours and fine and dispersed chromatin with inconspicuous nucleoli (Figure 1). Immunohistochemical stains demonstrated that the infiltrates were positive for MPO, CD43, with weak CD68 expression, and negative for CD34, CD117, CD20, CD79a, CD5, CD3 and cyclin D-1 (Figure 1).
