Abstract
The peripheral blood cells of a patient with acute plasma cell leukemia were examined with transmission (TEM) and scanning (SEM) electron microscopes. The TEM features of the immature plasma cells comprised lobulated and irregulary shaped nuclei, with scanty heterochromating and bizarre nucleoli, parallel arrays of endoplasmic reticulum, cytoplasmic fibrils and numerous polymorphic mitochondria. SEM examination of the cells showed long, thin irregular ruffles, or round blebs on the cell surface, with appearance different from this observed on other types of leukemia. A remarkable clinical and hematological remission was achieved with administration of melphalan and steroids. Die peripheren Blutzellen eines Patienten mit akuter Plasmazell-Leukämie wurden mit Transmissions-(TEM) und Raster-(SEM) Elektronenmikroskopie untersucht. Die unreifen Plasmazellen zeigten im TEM gelappte und irregulär geformte Kerne, mit spärlichem Heterochromatin und bizarren Nukleolen, parallele Anordnung von endoplasmatischem Reticulum, zytoplasmatische Fibrillen und zahlreiche polymorphe Mitochondrien. Im SEM waren dünne, längliche oder Kolben-förmige Auswüchse an der Oberfläche zu sehen, die deutlich von den Auswüchsen an der Oberfläche bei anderen akuten Leukämien abwichen. Eine weitgehende klinische und hämatologische Remission wurde mit der Verabreichung von Melphalan und Corticosteroiden erreicht.Keywords
