[Primary granulocytic sarcoma of the pancreas: efficacy of early treatment with intensive chemotherapy].

In the absence of systemic chemotherapy after the diagnosis of primary granulocytic sarcoma (PGS), all patients will subsequently develop acute myelogenous leukemia (AML). The authors describe a case of PGS of the head of the pancreas found at laparotomy in a 32-year-old man. The patient received early after surgery, two courses of high-dose chemotherapy and, with a follow-up of 2 years, never developed AML. This rare observation illustrates the necessity of further early systemic chemotherapy after surgical excision of PGS.
