The case report of a 61 year-old man with AML M2 FAB, t(1; 13; 14) and
zygomycotic mesenterial thromboangiitis is presented. Two induction c
ycles of chemotherapy were administered due to primary drug resistance
. They were complicated by pneumonia, colonic pseudo-obstruction and p
erforation with peritonitis. The patient died on the 40th day of thera
py, 4 days after undergoing palliative surgery. Zygomycotic thromboang
iitis, which very probably contributed to the intestinal perforation,
was confirmed morphologically at necropsy. The novel complex chromosom
al translocation t(1; 13; 14) (q31; q32; q24) and the problems connect
ed with the diagnosis of invasive fungal infections are discussed.
