BACKGROUND
Dermoid cyst, a developmental benign choristoma, is the most common orbital tumor of childhood, arising from ectodermal sequestration along the lines of embryonic fusion of mesodermal processes, lined by keratinized stratified squamous epithelium and expanding slowly due to constant desquamation and dermal glandular elements. Approximately 80% are found in the head and neck region and comprise 3-9% all orbital masses.
PURPOSE
It is mandatory to know about the variable presentations of orbital dermoids and the surgical techniques that can be adopted based on the site, extent, age and aesthetic needs, presence of inflammation and possibility of intraoperative rupture.
SYNOPSIS
Orbital dermoids can be classified as juxta-sutural, sutural or soft tissue cysts; superficial or deep; intraosseous or extraosseous, and intraorbital or extraorbital. These smooth, painless, mobile or partially mobile lesions mostly present at the fronto-zygomatic suture with proptosis, displacement, ptosis or diplopia, depending on depth and extent. Therefore, it is important to understand the various presentations and the appropriate surgical techniques.
HIGHLIGHTS
We describe the embryological origin, types and clinical features of dermoids in this video and demonstrate the surgical and minimally invasive techniques for their management.

Dermoid cyst is a congenital and benign disease with most occur on the head and neck. It is rarely that occur on the nasal tip and nasal septum at same time and rarely repair of using nasal septum mucosa. The authors treated a child with dermoid cyst in the nasal tip and septum. Only the dermoid cyst at the tip of the nose caused the change of appearance. Dermoid cyst of nasal septum did not cause any clinical symptoms. She underwent excision of the dermoid cyst at the tip of the nose and endoscopic surgery for the dermoid cyst in the nasal septum and used the nasal septum mucosa for repair at the same time. After 6 months of recovery, the appearance of the nasal tip recovered well without obvious scar, the nasal septum area recovered well, and the local stoma was unobstructed without recurrence. The authors found that this kind of nasal septal cyst with no clinical symptoms can achieve good therapeutic effect through endoscopic surgery and repair of using nasal septum mucosa, with less damage, rapid recovery, and good prognosis.

Review
Dermoid cysts are rare benign tumors that arise from ectopic epiblastic inclusions and account for 0.4% to 1.5% of all tumors. They are usually 1 to 5 cm in size and composed of a pasty semisolid material. The orbital dermoid cyst is the most common type. Dermoid cysts can also occur in the spinal cord, ovaries, and pancreas. We encountered a 24-year-old man with a dermoid cyst over the left sternoclavicular joint. He reported intermittent secretion of a white tofu-like exudate from an underlying congenital sinus tract since birth. The secretion had turned hemorrhagic for the last month and had been accompanied by progressive swelling and pruritus for 1 week. Ultrasonography and magnetic resonance imaging revealed characteristics of a dermoid cyst, and histopathological examination confirmed the diagnosis. The patient underwent surgical excision of the cyst under local anesthesia. The incision healed well with no postoperative complications. Considering that a dermoid cyst has the potential to become infected or progress into squamous cell carcinoma, its removal at an early stage is suggested. Few reports in the literature have described a dermoid cyst that secretes hemorrhagic contents from a congenital sinus tract. We present this case to provide a reference for clinicians.

Review
BACKGROUND A dermoid cyst is a benign, epithelial-lined cavitary lesion composed of ectoderm and mesoderm that can arise anywhere in the body, with a tendency to develop in midline structures such as the coccyx and ovary. It is a rare entity in the head and neck region, where the incidence is 7% of all body dermoid cysts. Of these 7% (dermoid cysts found within the head and neck area), 80% are found localized to areas around the orbit, oral region, and nasal region. Within the parotid gland, they are extremely rare, with less than 25 cases reported in the existing literature. CASE REPORT We report a case of a 26-year-old woman with a long-standing left parotid mass that was found to be a dermoid cyst after surgical excision and histological evaluation. We examine the clinical presentation and imaging findings used to establish a presumptive diagnosis to guide treatment options. Although preoperative fine-needle aspiration was not performed in this case, it is often used to clarify the differential diagnosis before definitive surgical management is undertaken. CONCLUSIONS Intraparotid dermoid cysts are rare, benign entities that require complete cystectomy for definitive management. As surgical excision is the only curative method, preoperative histopathological diagnosis via biopsy may be unnecessary. Our paper adds to the existing literature by presenting a case of an intraparotid dermoid cyst successfully treated surgically in a 26-year-old woman.

BACKGROUND
The precise diagnosis of dermoid cysts, which are usually located deeper than other common cysts, is important because dermoid cysts occasionally recur after incomplete excision. Ultrasonography (US) could give useful preoperative information of dermoid cysts but only a few studies have been conducted on US findings related to dermoid cysts. This study aimed to investigate clinical and US findings on pediatric dermoid cysts.
METHODS
We retrospectively reviewed the medical records, clinical photographs, and US findings of 31 pediatric patients (≤18 years of age) with histopathologically diagnosed dermoid cysts who visited the Pusan National University Hospital between 2007 and 2016.
RESULTS
Of the 31 patients, 25 underwent ultrasonography. The mean long diameter, short diameter, and depth of the cysts were 12.7, 9.0, and 3.8 mm, respectively. Sixteen cysts (64%) were ovoid, 23 (92%) showed hypoechogenicity, 20 (80%) showed heterogeneity, 19 (76%) showed well-demarcated outer margins, and all cysts showed positive posterior acoustic enhancement. All cysts extended to the subcutaneous tissue, and 15 (60%) showed a connection with the underlying muscle.
CONCLUSIONS
Ultrasonography may be a useful diagnostic method to visualize the extent and location of the dermoid cyst and make an accurate diagnosis prior to surgical intervention.
