For PPRV diagnosis in the examined species, tissue of the lymphoreticular system, in particular tonsils (Figure 2, panel D), head and lung-associated lymph nodes, mesenteric lymph nodes, and small intestinal Peyer's patches, were found most suitable for postmortem diagnosis with PCR and immunohistochemistry.
Due to her clinical symptoms, upper endoscopy was performed, and a variegated fungating mass with very prominent lymphoreticular nodularity and friability was found along the medial aspect of the lesser curvature of the stomach at the juncture of the body with the antrum.
Extramedullary involvement of GIT with leukemia is rare as most patients are more likely to present with involvement of lymphoreticular organs and sanctuary sites such as the brain, testes, and ovaries.

Introduction: The Wiscott Aldrich syndrome (WAS) is X-linked recessive disorder associated with microplatelet thrombocytopenia, eczema, secondary pyogenic and an increased risk of autoimmunity and lymphoreticular neoplasia.
