60. SCLC
Small Cell Lung Cancer
The tumor is composed of diffuse proliferation of small to
intermediate sized cells (arrow) generally with very scant
cytoplasm and round to oval hyperchromatic nuclei. The tumor
cells are generally larger than small lymphocytes (left
arrowhead) but in some cases the morphologic distinction may
be impossible.
