BACKGROUND: Submental dermoid cysts are uncommon midline cysts which occur due to entrapment of ectoderm between the second and third branchial arches during embryogenesis. Most dermoid cysts of the head and neck are benign, but rarely malignant transformation may occur. To the best of our knowledge, this is the first report of a carcinosarcoma arising in a submental dermoid cyst. CASE PRESENTATION: A 42-year-old Sri Lankan Tamil man presented with a large cystic swelling in his submental region which was diagnosed as an extensive submental dermoid cyst...

PURPOSE: We report our experience in managing a group of patients with Currarino syndrome, highlighting diagnostic challenges, surgical techniques, in addition to a review of current neurosurgical options. PATIENTS AND METHODS: The study included patients with Currarino syndrome who presented to our pediatric surgery department during the period 2010 through 2016. The 'sacral scimitar' in plain X-ray provided the clue for the diagnosis; while MRI examination was essential to define the nature of the presacral mass and associated spinal anomalies...

A 25-year-old man with Type 1 diabetes mellitus experienced rapid visual decline and was scheduled for right cataract surgery. At the time of administering an inferotemporal retrobulbar block, a white discharge appeared spontaneously on the surface of the globe. Superotemporally a cyst was found and its contents were subtotally evacuated. Microscopically, eosinophilic, acellular material with chatter artifact and small vacuoles was detected and initially thought to represent a lens choristoma. This material stained moderately with the periodic acid Schiff method and was focally Congo red positive without apple green birefringence; it also stained blue with the Masson trichrome method...

Mature cystic teratomas (MCT), also known as dermoid cysts, are the most common ovarian germ cell tumors and the most common ovarian neoplasms in patients younger than 20 years. Malignant transformation (MT) is a rare complication of MCTs which may occur in 1-2% of the cases. Squamous cell carcinoma (SCC) is the most frequent histology arising from MCTs and its appearance depends on diverse risk factors such as patient's age, the size of the tumor and levels of serum tumor markers. Diagnosis and treatment constitute a big challenge due to the rarity and the aggressive course of this entity...

Extrarenal Wilms' tumor of the ovary is a very rare tumor likely derived from embryonic mesonephros. We present the first reported case of a teratoid extrarenal Wilms' tumor of the ovary with a short review of the existing literature. In the case, a 26-year-old woman presented with back pain and was found to have a dermoid cyst; three years later, she presented again, now pregnant, with severe abdominal pain. She was diagnosed with an immature teratoma consisting of a Wilms' tumor (immature component) arising within a mature teratoma and treated exclusively with surgery and surveillance...

Nasal dermoid sinus cysts are rare congenital lesions that may lead to recurrent soft tissue infections and severe intracranial complications. In case of an intracranial extension, the traditional surgical approach includes a frontal craniotomy with significant morbidity. As a less invasive alternative, a transnasal endoscopic approach has been recommended.This report describes the transnasal endoscopic resection of an intracranial nasal dermoid sinus cyst via an open rhinoplasty approach, which achieved a wide surgical exposure with minimal invasivity and ideal aesthetic results...

Haberland syndrome or Fishman syndrome also known as encephalocraniocutaneous lipomatosis (ECCL) is a rare, congenital neurocutaneous disorder. It is characterized by unilateral involvement of skin, eyes and central nervous system. We report the case of a 28-year-old woman who presented with soft lipomatous swelling over right temporal area with nonscarring alopecia of part of frontal and parietal region. The patient had a history of seizures and ipsilateral scleral dermoid. Computed tomography scan findings were suggestive of lipomas and calcification of falx...

OBJECTIVE: To assess whether computed tomography (CT), magnetic resonance imaging (MRI), and neurosurgical evaluations altered the diagnosis or management of children diagnosed with benign macrocrania of infancy by ultrasonography (US). STUDY DESIGN: We queried our radiology database to identify patients diagnosed with benign macrocrania of infancy by US between 2006 and 2013. Medical records of those with follow-up CT/MRI were reviewed to determine clinical/neurologic status and whether or not CT/MRI imaging resulted in diagnosis of communicating hydrocephalus or required neurosurgical intervention...

REVIEW
Ruth Elizabeth Brown, Srikrishna Harave
Neck masses are frequently encountered in pediatric medicine, and can present a diagnostic dilemma for the clinicians involved. There are several means by which neck masses in children can be subdivided, for example by age at presentation, anatomical location including compartments and fascia of the neck, their classical appearance when imaged, or by etiology. When imaging children the clinicians must be mindful of radiation exposure and as such ultrasound (US) is often attempted first. Cross sectional imaging can be helpful for problem solving with CT being particularly useful for assessing the patient in more acute scenarios, for example when there is airway compromise...

The authors describe a 4-year-old girl presenting with a 2-year history of a superomedial eyelid "bump" that appeared cystic on MRI. The clinical diagnosis was dermoid cyst, possibly of conjunctival origin. Following excision, histology showed a cyst that contained keratin and lanugo hairs in its lumen with sebaceous glands and chronic inflammation in its fibrous wall. An unanticipated finding was the presence of a trichilemmal (pilar) variety of epithelial lining that stained positively for calretinin, an immunostain that identifies trichilemmal epithelium...

Epidermoid cyst occurring within the tongue is rare. A 5 year old male child was brought to OPD with a tongue mass which was gradually increasing in size. There was associated difficulty in speech and mastication as the swelling increased in size. Intraoral examination revealed moderately tender,fluctuant and enlarged tongue. A diagnosis of dermoid cyst was made and the patient was booked for surgery. Excision of the cyst was done under general anaesthesia. Post-operative histopathology was done. The histopathological findings confirm the diagnosis of an epidermoid cyst, characterized by the presence of: (I) a cyst cavity lined by stratified squamous epithelium with keratinization on the surface; and (II) connective tissue with a mild inflammation...

Interdural dermoid cysts (DCs) of the cavernous sinus (CS), located between the outer (dural) and inner layer (membranous) of the CS lateral wall, are rare lesions in children. The authors report on a 5-year-old boy with third cranial nerve palsy and exophthalmos who underwent gross-total removal of an interdural DC of the right CS via a frontotemporal approach. The patient had a good outcome and no recurrence at the 12-month follow-up. To the best of the authors' knowledge this is the second pediatric case of interdural DC described in the literature...

The nonoperative management of sylvian fissure dermoid/epidermoid cysts presents a risk that is difficult to quantify. With rupture, potentially fatal complications such as chemical meningitis, hydrocephalus, fever, seizure, or meningeal irritation may occur. In this paper, we present an asymptomatic case of such a cyst with imaging evidence of prior rupture, and we review the literature for the likelihood of future complications. We use for illustration a case of a 68-year-old woman with imaging features of a sylvian fissure epithelial inclusion cyst who refused surgical intervention and review the literature for further investigation...

There is a wide group of lesions that may exist in the sellar and suprasellar regions. Embryologically, there is varying evidence that many of these entities may in fact represent a continuum of pathology deriving from a common ectodermal origin. The authors report a case of a concomitant suprasellar craniopharyngioma invading the third ventricle with a concurrent frontal lobe cystic dermoid tumor. A 21-year-old man presented to the authors' service with a 3-day history of worsening headache, nausea, vomiting, and blurry vision...

Heterotopic gastrointestinal cysts of the oral cavity are benign lesions usually discovered during infancy. Their pathogenesis is not very clear. They are rare congenital anomalies that result from remnants of foregut-derived epithelium in the head, neck, thorax or abdomen during embryonic development. The majority of these lesions occur in the anterior ventral surface of the tongue and extend to the floor of the mouth. They are confused clinically by surgeons in cases of head and neck masses in children as ranulas, dermoid and thyroglossal cysts, and lymphangioma...

A 20-month-old male miniature dachshund was evaluated for a 10-week history of intermittent stranguria, pollakiuria, haematuria and obstructive urolithiasis. Retrograde urethrocystography revealed a subcutaneous saccular structure in the perineal area connected to the intrapelvic urethra associated with urolithiasis. After excision of the perineal saccular structure, microscopical examination confirmed the presence of transitional epithelium lining the diverticulum, with isolated submucosal smooth muscle bundles...

To investigate effects of surgical treatment on adult tethered cord syndrome (TCS).A retrospective analysis of 82 adult patients (17 male cases, 82% and 24 female cases, 59%) with TCS treated by surgery was conducted between March, 2005 and December, 2015, with an average age of 31.6 years and average disease course of 6.7 years. All the 82 cases of patients received nerve electrophysiology monitoring assisted microsurgery. After surgery, all patients were followed up for an average of 2.5 years. Surgical effects were evaluated according to Hoffman grading system...
