3. LYMPH GLAND ENLARGEMENTS
There a few hundred lymph glands located in the head and neck.
They are in the main distributed in the superficial location
shown in Fig.Above
They are enlarged whenever there is an inflamatory disorder in the area of drainage of these glands.
In later life they are enlarged because of malignant tumours in the area of their drainage.
Therefore in lymph gland enlargements of the
neck the oral cavity, oesophagus lungs and thyroid need physical examination and investigations.
Lymph glands also get enlarged in cases of glandular
fever(Infections, mononucleosis). This produces bilateral
multiple lymph nodes fever and sore throat. This is a viral fever.

One or more of these glands may be associated with a discharging sinus.
