We present a newborn of 20 days of life attended at the emergency room for irritability, with the only finding on physical examination of two oral ulcers.

[Surgical complications in salvage surgery of patients with head and neck carcinomas treated with concomitant chemoradiotherapy (CCR)].

Introduction: One way of treating head and neck carcinomas is using concomitant chemoradiotherapy (CCR). In this study we will try to evaluate the incidence of complications in rescue surgery after CCR.

Material And Method: We have studied data from 103 patients diagnosed as having stage III or IV squamous head and neck carcinoma between 1997 and 2005.

We focus on an exceptional case report about a patient that presented a great necrotic lesion in the middle of the tongue due to a bilateral external carotid thrombosis, because of a radiation therapy some years before.
