Özet:

Dermoid cysts are congenital pathologies that have squamous epithelial lining of ectodermal origin. They include different epidermal appendages (sebaceous glands, hair follicles, sweat glands,sometimes, fat, bone, nails, teeth, eyes, cartilage, and thyroid tissue). Cyst lumen is filled with keratin, sebaceous material and sometimes hair.Because it contains mature tissue, a dermoid cyst is almost always benign. The rare malignant dermoid cyst usually develops squamous cell carcinoma in adults; in babies and children it usually develops endodermal sinus tumor. Dermoid cysts are true hamartomas. Complete surgical excision of dermoid cysts is recommended because of the possibility of malignant degeneration. In this study we present a nasal dermoid cyst and surgical approach, reconstruction.
