Primary granulocytic sarcoma of the small bowel.
A young man developed obstruction of the small bowel due to a neoplastic process, which in retrospect proved to be a primary granulocytic sarcoma, preceding acute granulocytic leukemia for more than 3 years. The histologic, histochemical and ultrastructural findings are presented, together with a review of the literature on granulocytic sarcomas, particularly those presenting as aleukemic forms. It is suggested that these forms may not be so rare and that careful search, using currently available methods, will be rewarding.
