IvYMPHADENlTlS. INFI^AMMATION OF THE IvYMPH 



GI.ANDS. 



Result of lesions of tributary tissues. Arrest in glands of microbes and 

 other irritants. Trauma of gland. Inflammation. Symptoms: swelling, 

 stiffness, gland tender, hot, pitting envelope, corded lymph vessels, abscess,, 

 fever. Lesions. Treatment: antiseptics, astringents, emollients, vesicants, 

 lancing, antiseptics, antiphologistics, antithermics. Chronic adenitis. 

 Symptoms: enlarged glands without engorgement, if simple affects a single 

 gland, if infectious, a group. Lesions: gland swelling, induration, shrink- 

 ing, follicular distension, pigmentation, growth of lymphocytes, caseation, 

 calcification. Treatment: antiphlogistic, antiseptic, iodine, chloride of 

 calcium, iodide of potassium. 



Apart from traumatic lesions, lymphadenitis virtually implies 

 some lesion of the tissues from which the different vessels of the 

 glands proceed. The glands, however, have been referred to as 

 filtering agents on the course of the lymph vessels and in this 

 partial view of their functions we find abundant reason why irri- 

 tants, carried in the lymph stream, should be arrested with patho- 

 genic results in the glands. A particle of pigment, gaining en- 

 trance to the lymph vessels, tends to be arrested among the 

 trabeculae of the gland, and contributes to the pigmentation so 

 common in old animals. Cells and granules from malignant 

 tumors, and bacteria from an infection-atrium are arrested in the 

 glands and make these the great centres of infection lesions. 



Traumatic inflammation comes from bruises, punctures or 

 incisions directly implicating the glands. Tbere result swelling, 

 tenderness and the other general signs of inflammation, and in 

 the case of an open wound possibly lymphorrhagia. 



Acute inflanifnatton more commonly supervenes on inflamma- 

 tion in the area drawn upon by the afferent vessels of the gland. 

 In infiammations generally, the adjacent lymphatic glands become 

 congested. In lymphangitis it is so in a marked degree. In 

 external parts we can follow this by careful observations during 

 life, in internal organs we often find the glandular enlargement 

 after death. 



Symptoms consist in swelling and perhaps stiffness in the re- 

 gion of the gland. Manipulation shows tenderness and heat, the 

 gland being felt abnormally large, round, or oval, tense, loose
