Abstract

PATHOLOGIC QUIZ CASE 1  Karen H. Calhoun, MD, Galveston, TexA 17-year-old male had a three-year history of a nontender right-sided preauricular mass that had enlarged rapidly over the previous six months. The mass had never drained or become infected. The patient had no history of otalgia, otorrhea, loss of hearing, or facial nerve weakness.Physical examination revealed a 4.0 × 4.5-cm nontender rubbery mass in the preauricular area. Fine-needle aspiration yielded about 4 mL of turbid straw-colored fluid. No acid-fast or fungal organisms were seen, no organisms grew on culture, and the cytopathologist could not make a definitive diagnosis.Superficial parotidectomy was performed. A cystic mass in the superficial lobe was firmly adherent to the cartilage of the external auditory canal, some of which had to be excised to remove the mass. Photomicrographs of the mass are shown in Figs 1 and 2.What is your diagnosis?
