Surgical Pathology Case
 

CLINICAL INFORMATION

 

A 65-year-old gentleman had a right parotid mass for approximately three to four months.  The patient denies any tenderness of this area.  He also denies any dysfunction of his facial musculature.  The patient does also state that he did have cyst removed behind both of

his ears approximately 45 years ago.  He is not sure exactly what these were, but states that they were some form of a cyst.  He does also

report remembering that he thought these areas have some form of a drain in them.  Otherwise, the patient denies any significant issues including any difficulty with swelling, pain with swelling, changes in voice, hoarseness, coughing of blood, or ear pain.  He denies any changes in  his hearing, nasal bleeding or blockage, sores in his mouth, sore throat, loose teeth, or any changes in skin lesion.

GROSS DESCRIPTION

 

The right parotid specimen consists of a large fragment of firm, yellow/tan/brown soft tissue measuring 5.9 x 4.0 x 2.1 cm and weighs 29.8 grams. Serially sectioning reveals a lobular, white/tan/yellow, firm mass measuring 3.0 x 2.4 x 1.7 cm.  A solitary cyst is identified adjacent to the mass and is filled with a translucent yellow gelatinous material.  The cyst measures 0.6 cm in greatest dimension. The mass is well-demarcated and does not appear to extend to the external surface.
