May 2019 — Anatomic and Clinical Pathology: Case 3
A 23 year old presents to his family care physician with a five-month history of right-sided facial numbness and eyelid twitching. He is a non-smoker and has no previous malignant history. An ultrasound of his face showed a 3-4 cm hypoechoic mass in the parotid. An outside biopsy was positive for a “round blue cell tumor.” Clinically the mass was rapidly enlarging over the course of weeks-months. A CT of the mass is shown.
