SALIVARY TUMOR BLOCKING PHARYNGEAL OPENING OF LEFT EUSTACHIAN TUBE

I am reporting this case because the microscopic changes and the location of the tumor are most unusual. Undoubtedly this was a congenital misplacement of tissue. A woman, aged 19, single, was troubled with occasional attacks of grand mal, tubotympanic catarrah and deafness.
