Functional and morphologic characteristics of the leukemic cells of a
patient with acute monocytic leukemia: correlation with clinical features
CA Schiffer, FT Sanel, BK Stechmiller and PH Wiernik
The clinical course of a patient with acute monocytic leukemia and
prominent infiltration of the skin and testes is described. In vitro
studies demonstrated that the circulating monocyte precursors were capable
of adherence to nylon fibers, and phagocytosis of bacteria and latex
particles. In vivo, migration of leukemic cells to skin windows was
observed. Extreme nuclear folding, marked surface activity, and morphologic
features suggesting nuclear and cytoplasmic maturation were seen by light
and electron microscopy. The presence of morphologically and functionally
more differentiated monocytic cells may account for the marked tiuuse
invasion in this patient and, possibly, in other patients with monocytic
leukemia.
