AN ALVEOLAR SARCOMA 



FIG. 32. ALVEOLAR SARCOMA OF THE BREAST. (Camera drawing /.., out- 

 lines drawn with Leitz's drawing eye-piece and yVinch oil-immersion, x 800 

 diameters.) 



A fully developed part of the tumour : i, In the centre of the field, a large fibro- 

 blast with lobed nucleus containing four intranuclear bodies ; 2, two bodies 

 similar to those in the interior of the nucleus at i, free and fusing together 

 with a peripheral extension ; 3, a granular intranuclear body with a dense 

 chromatic nucleus sending rays into the periphery and forming chromidial 

 granules by fusion with cytoplasm ; 4 and 5, free amoeboid bodies containing 

 chromatin and forming granules, the latter similar to those in 3 ; 6, a free body 

 with a dense chromatic part sending processes into the non-chromatic peri- 

 pheral part ; 7, a body similar to 6, but without differentiation of chromatin.
