RESUMO
El carcinoma escamoso de conducto auditivo externo es poco frecuente. La sintomatología puede semejar una otitis externa u otitis media crónica, lo que puede retrasar el diagnóstico. La falta de un sistema de clasificación y el número limitados de casos hace difícil la elaboración de guías de tratamiento. Se describe una serie de casos de esta neoplasia, asf como una revisión de la literatura actual.
Squamous cell carcinoma of the external auditory canal is rare. The symptoms may resemble an external otitis or chronic otitis media, which can delay diagnosis. The lack of a classification system and the limited number of cases makes it difficult the development of treatment guidelines. We present a case series of this neoplasia, as well as a review of the literature.

INTRODUCTION: Peripheral arterial disease is a severe manifestation of atherosclerosis that can lead to critical ischemia of the lower limbs and is also associated with high cardiovascular risk. Diagonal lobular and anterior tragal ear creases have been associated with coronary artery disease, but they have not yet been investigated in patients with peripheral arterial disease. OBJECTIVES: To evaluate the prevalence of ear creases among patients with peripheral arterial disease of the lower limbs, compared with patients without documented atherosclerotic disease. METHODS: Cross-sectional study including 60 male patients with peripheral arterial disease of the lower limbs and 60 dermatologic outpatients matched for age and gender. The associations were adjusted for other risk factors by conditional logistic regression. RESULTS: The prevalence of diagonal and anterior tragal ear creases was higher among cases (73 percent vs. 25 percent and 80 percent vs. 43 percent, respectively) than controls; these associations remained significant even when adjusting for other known risk factors of atherosclerosis (odds ratio = 8.1 and 4.1, respectively). CONCLUSIONS: Ear creases are independently associated with peripheral arterial disease and may be an external marker for risk identification.
