The authors observed the clinical and histopathologic features of gingival and skin infiltration in 1,076 leukemia patients from 1966 to 1982. Of these, 66 (6.1%) had leukemia infiltration in the skin or gums, 33 (50%) were confined to the gums, 28 (42.2%) were limited to the skin, and 5 (7.6%) occurred in the gums and skin. 27 patients without teeth had no gingival infiltration. The incidence of gingival infiltration was highest in acute monocytic leukemia (66.7%), followed by acute myelomonocytic leukemia (18.5%) and acute myelocytic leukemia (3.7%). Gingival infiltration in the clinical manifestations of the gingival papilla, free sacral, attached sacral swelling, and some of the proliferation of covering the majority of the crown, was bright red to purple, squamous epithelium is complete, thin
