Abstract:
A dermoid cyst is an ectodermally differentiated form of teratoma. Its occurrence in the parotid gland is very rare. Such a presentation must be properly evaluated in order to rule out malignancy. We describe the diagnostic evaluation and surgical management of a parotid dermoid cyst in an 18-year-old man. We also review the embryologic pathogenesis of the tumor and the usefulness of the physical examination, preoperative fine-needle aspiration cytology, magnetic resonance imaging, and computed tomography in evaluating the extent of the tumor, its histologic features, and its cystic characteristics. Finally, we discuss the role of surgical management in terms of preserving facial nerve integrity and preventing recurrence.

Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
