Obstructive jaundice. An unusual presentation of granulocytic sarcoma

A 36-year-old woman presented with obstructive jaundice, found at laparotomy to be due to a granulocytic sarcoma in the head of the pancreas. Six months later she developed lymphadenopathy in the left supraclavicular fossa. In spite of chemotherapy containing cytarabine and vincristine, she developed acute myeloid leukaemia (French-American-British [FAB] type M4) 16 months after the onset of her illness.
