|Description:||This 1952 photograph depicted a Goroka, New Guinea woman exhibiting the tell tale signs of what turned out to be a parotid salivary gland tumor. The patient also tested positive for yaws, a cutaneous infection caused by the Gram-negative bacterium, Treponema pallidum pertenue, a subspecie of the specie Treponema pallidum, of which T. pallidum pallidum, the pathogen responsible for syphilis, is also a member.|
The parotid gland is the largest of the salivary glands, and is paired with another on the opposite side of the jaw, just lateral to the temporomandibular joint (TMJ). It is through this gland that a major motor nerve passes known as the facial nerve, which innervates the facial muscles on the same side of the face. Therefore, it is imperative that the surgeon removing this tumor avoid as much as possible, damaging this nerve during the procedure.
