PATHOLOGIC QUIZ CASE 1
Dennis A. Greene, MD, Chicago
A 45-year-old white man noticed a lump beneath his left ear approximately six months prior to admission. During the last month prior to admission, the mass enlarged markedly and became tender. The patient denied hearing loss or facial weakness. On examination, a 3-cm, firm, fixed, slightly tender mass was present in the retromandibular fossa. Facial nerve function was normal. There were no cervical masses. Soft tissue x-ray films were normal. At the time of surgery, the mass was found to be confined to the superficial portion of the parotid gland. It was densely adherent to the surrounding fascia and to the branches of the facial nerve. The mass was cystic and contained necrotic, grayish, viscid material. A total superficial parotidectomy, sparing the facial nerve, was performed. Representative microscopic sections may be seen (Fig 1, 2, and 3).
