LYMPHADENITIS. INFLAMMATION OF THE LYMPH 



GLANDS. 



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 lympd vessels, abscess, 

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

 lancing, antiseptics, antiphlogistics, 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 hs 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 trabeculse 

 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 in- 

 cisions directly implicating the glands. There result swelling, 

 tenderness and the other general signs of inflammation, and in 

 the case of an open wound possibly lymphorrhagia. 



Acute injlammatioti more commonly supervenes on inflamma- 

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

 In inflammations generally the adjacent lymphatic glands become 

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

 ternal 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
