Unusual Ear Mass

Anita Jeyakumar, Matthew Keisling

17 year old female with a history of stage IVS neuroblastoma diagnosed at the age of 4 months. She received cis-retinoic acid post radiation and completed all therapy at the age of 4 years. During a routine audio logic visit, she was noted to have a mass in her right ear (Figure 1). A CT scan was done which showed a small homogenous well circumscribed mass in the left external auditory canal (Figure 2). The mass was biopsied in both left and right ear and the pathology is shown in Figure 3, with a diagnosis of a Schwannoma.
