Preauricular adenopathy may be a component of "occuloglandular fevers" resulting from adenoviral conjunctivitis, sarcoidosis,tularemia,cat-scratch disease, and other processes.

Posterior auricular or posterior cervical adenopathy frequently reflects infections of the scalp but may also be prominent in systemic processes, such as rubella or toxoplasmosis.

 

 http://www.peditips.com/when a doctor completes his training without the real hands on experience, its mistaken by many that what you are taught in medical school is totally in contrast with what you see clinically in patients. This blog aims at making medical students and docs understand how every case is exactly the same as in books. The work done by senior docs over the years is really rewarding. Infact when one finds a contrast in what is taught, he should go to books and you will find the exact descriptions verbatim, or the images as they are explained in medical books.
