Sclerosing angiomatoid nodular transformation of the splenic red
pulp has been described quite recently; many of the lesions previously
diagnosed as splenic exuberant granulation tissue, multinodular
hemangioma, and inflammatory pseudotumor could actually belong
to this category. The lesion has been well reported intermittently in
the past, but new cases with still newer associations keep appearing
from time to time. There are no known risk factors and no inciting
triggers have been proven. We report two such cases- one of which
has extensive extramedullary haematopoiesis; a feature that has
never been reported earlier. Clinico-morphological and radiological
features along with pathogenesis are discussed in detail.
