TUMORS. 



varying number of lymph-vessels (Hebra), and the cavernous fympli- 

 angioma, composed of a large number of sinuous lymph- vessels 

 and a comparatively scanty amount of connective tissue. Simple 

 lymph-angioma is not of rare occurrence in the tissue of the skin r 

 and usually appears in the form of numerous hard, compressible 

 tumors the size of a lentil or of a hazel-nut. Cavernous lymph- 

 angioma is rare, and, as a rule, deeply situated in the subcu- 

 taneous or subfacial tissue, producing sometimes very large 

 tumors. Ulceration of these tumors occasionally takes place, 

 with a continuous oozing of lymph. (See Fig. 212.) In macro-

glossa, the congenital enlargement of the tongue, of mainly its 

 anterior portions, the mass consists of a fibrous connective tissue 

 with numerous sinuous lymph- vessels, and is, therefore, cavernous 

 lymph-angioma (Virchow). In some cases, cavernous blood- 

 angioma was observed. No new formation of striped muscles 

 was found in the tumor.
