Title: Resection of dermoid cyst in the retroauricular region. Case Report.


Dermoid cyst is a developmental cystic malformation, described in the scientific literature as a benign teratoma, uncommon in the head and neck region. Most of them affect more commonly the floor of the mouth, being able to be located laterally or in other place. The etiology still uncertain, however, it is believed to be associated with ectoderm remnants trapped in the first and second branchial arches throughout the third and fourth weeks of intrauterine life. The characteristics of the dermoid cyst are slow and painless growth. Clinically, it presents itself as a nodule, with fluid or semi-solid content and soft to the touch. The lesion occurs more frequently in children and young adults, without predilection for sex. The definitive diagnosis is only obtained from the histopathological exam. The most indicated treatment is the complete surgical resection of th cystic material. When completely removed, there are no reports of recurrence. In about 1% of dermoid cysts, malignant transformation occurs. The present manuscript discusses the clinical and histopathological findings of a clinical case of dermoid cyst in a 16 years old male patient, melanoderma, who searched the Maxillofacial Surgery Service at the Federal University of Pernambuco, reporting approximately 3 years of the lesion evolution. The treatment adopted was the complete cystic resection.
