The aim of this work is to show the important histiocytic poblation prescnt in a case of stomach medullary carcinoma, marked with
silver technique of Del Río Hortega. This carcinoma is poor differentiated with a predominani lyrnphoid infiltrate, of beter prognosis, that sharcs many characteristic with medullary carcinoma of breast, lung, nasopharynx, thymus and salivary glandS. Histologic techniques: Hematoxilin & Eosin, PAS, PAS-Alcian blue, Alcian blue, Masson's thrichrome, macrophagues Del Río Hortega-Polak, and reticulin Del Rio Hortega si Iver impregnations techniques. Gastric medullary carcinoma shows an importante lymphoid infiltration T and B, and dendritic, plasmodials and giant multinucleated macrophagues in close relations with neoplasic cells.
The results suggest that Epstein-Barr virus (EBV) become.s associated with gastic medullary carcinoma.
