CHAPTER XVII. 



Other Diseases of the Subepithelial Lymphatic 

 Glands. 



The subepithelial lymphatic glands may share with 

 other lymphoid tissues in certain obscure infections, 

 namely splenomedallary leuchaemia, lymphatic 

 leuchsemia, and lymphadenoma (Hodgkin's disease). 

 In the latter disease it is the large glandular lympho- 

 cytes which multiply so rapidly at certain stages. The 

 lymphoid tissue of the faucial tonsil is also liable to 

 lymphosarcoma ; that is, a large round-celled sarcoma 

 which spreads to the adjacent lymphatic glands. Malig- 

 nant disease of the epithelial covering of the lymph 

 nodes is also to be met with in stratified epithelioma of 

 the tonsil, and the not very malignant carcinoma of the 

 vermiform appendix. 



None of these diseases, however, appear to have any 

 bearing on the main thesis of this book. 



Of more import is the insidious passage of tubercle 

 bacilli through the subepithelial lymph glands to the 

 adjacent interstitial lymphatic glands. This condition 

 is of very frequent occurrence, the upper cervical 

 glands draining the faucial tonsil becoming tuberculous, 

 whilst that organ remains healthy. Cervical glands are 

 more liable to tuberculous disease than, for instance, 

 are inguinal glands, and the disease commonly begins 

 in the upper deep cervical glands which drain the tonsil.
