BACKGROUND. Bilateral squamous cell carcinoma (SCC) of the external ears is
a rare phenomenon, and we are unaware of instances of bilateral perineural
involvement.
OBJECTIVE. To describe bilateral auricular SCCs, each with perineural invas
ion.
METHODS. Case report and literature review.
RESULTS. Histopathologic examination revealed perineural invasion in both t
umors.
CONCLUSION. This appears to be an unusual presentation of bilateral auricul
ar SCCs with perineural invasion in an elderly immunocompromised patient.
