which contained a few residual elements including a Reed-Sternberg cell 

 (Fig. 15-7C). It is assumed that the cellular nests generally encountered in

 {A) controlled In irradiation and chemotherapy for 

 5 years. Autopsy disclosed a desmoplastic type ol 

 Hodgkin's lymphoma, the tumor being composed 

 almost entirely of acellular collagenous tissue (B. 

 lower right), with scattered spaces containing a few 

 cellular elements, including a Reed-Sternberg form 

 (C).

Case e ). This was the case of a middle-aged man, a segment of whose colon 

 was removed along with a group of enlarged mesocolic lymph nodes be- 

 ( a use of partial obstruction. Sections <>l the latter showed the nodular type of 

 lymphoma (Fig. 158,/). while the tumor in the intestinal wall was made up 

 of an admixture ot lymphocytes and reticulum cells (Fig. 15-85).
