RESUMO
Dermoid cysts of the Pre-auricular area are extremely rare. We report one case of Pre-auricular dermoid Cyst. Case involved a gradually enlarging mass of the superior and anterior aspect of the pre-auricular region on left side. During the operation, a lesion was found just under the skin, not fixed parotid or adjacent cartilage. Histologically, specimen contained desquamated squamous epithelium and keratin in the lumen. Dermoid cysts at the pre auricular region are rare and a diagnostic challenge, but , it should be considered as a differential diagnosis in cases of painless long standing enlargement of parotid gland which is soft in consistency.
RESUMO
Summary: Odontogenic keratocysts (OKC) now officially known as Keratocystic odontogenic tumor (KCOT) is a benign odontogenic intraosseous tumor which is potentially agrressive having distinguished clinical and histopathological features. Based on a literature review, more aggressive treatment — either resection or enucleation supplemented with Carnoy’s solution with or without peripheral ostectomy — results in a lower recurrence rate than enucleation alone or marsupialization. WHO’s reclassification of this lesion from cyst to tumour underscores its aggressive nature and should motivate clinicians to manage the disease in a correspondingly aggressive manner. The purpose of this paper is to review and discuss the redesignation of KCOT and the implications for treatment.
