INTRODUCTION: Dermoid cysts (DCs) are unusual benign congenital intracranial tumors that typicallyarise in the midline and form as a result of abnormal sequestration of ectodermal cells during neural tubeformation. In all age groups, endoscopic approaches are preferable for the removal of sellar lesions. A 6-year-old girl with recurrent meningitis underwent endoscopic endonasal surgery forsellar DC. CONCLUSION: To the best of our knowledge, we present the first case of a suprasellar DC in a pediatric patient that was removed endoscopically...

Dermoid cysts are benign developmental anomalies that occurred as a result of the sequestration of the skin along the lines of embryonic closure. Those occurring in the cervicofacial region are uncommon, accounting for about 7% of all dermoids and its presence in postauricular region is further exceptionally rare. A healthy 19-year-old Asian boy presented with a unilateral postauricular cyst that had been present since childhood without any symptom. The computed tomography scan revealed an encapsulated tumor with no intracranial extension...

OBJECTIVE Epidermoid and dermoid cysts may be found along the cranial base and are commonly resected via open transcranial approaches. The use of endoscopic endonasal approaches for resection of these tumors has been rarely reported. METHODS The authors retrospectively reviewed the medical records of 21 patients who underwent endoscopic endonasal surgery for epidermoid and dermoid cyst resection at the University of Pittsburgh Medical Center between January 2005 and June 2014. Surgical outcomes and variables that might affect the extent of resection and complications were analyzed...

INTRODUCTION:  External angular dermoid cysts, or epidermoid inclusion cysts, are a common subcutaneous tumor of the head and neck. For the majority of these lesions, excision is relatively simple and performed through an incision immediately overlying the mass. Facial lesions in pediatric patients present a unique challenge in that a direct approach carries the potential for visible scar formation. OBJECTIVE:  This article aims to detail our experience with subcutaneoscopic excision of external angular dermoid cysts in pediatric patients using endoscopic instrumentation...

Background: Keratinous or epidermoid cysts (ECs) are encapsulated lesions lined by squamous cell epithelium. They comprise approximately 1% of intracranial lesions. Contrary to dermoid cysts, they lack dermal elements such as sebaceous or apocrine glands and hair follicles. The sellar region is the second most common intracranial site following the cerebellopontine angle. Here, we report a case of EC in a patient who complained of endocrine disturbances. We also performed a systematic review on previously published cases to analyze clinical and radiological characteristics and report the treatment outcomes of suprasellar ECs...

Electroconvulsive therapy (ECT) is considered relatively contraindicated in patients with intracranial space-occupying lesions. A 53-year-old male presented with a 5-year history of medication-refractory major depressive disorder. Brain imaging findings suggested the presence of a ruptured dermoid cyst in the transverse sinus and a calcified meningioma in the temporal lobe sulcal space. There was no evidence of mass effect. Neurofibromatosis was the only other clinical condition present. The patient had no clinical neurological deficits...

Background: Chronic subdural hematoma (CSDH) of the posterior fossa is uncommon in adults. Only a few cases have been reported, and most of these were secondary to head injury or anticoagulant therapy. We herein describe a case of successful surgical treatment of CSDH in the posterior fossa after surgical removal of a large supratentorial and infratentorial dermoid cyst. Case Description: A 71-year-old woman underwent removal of a left supratentorial and infratentorial dermoid cyst via a left transzygomatic approach...

A 4-year-old girl presented repeatedly with a complicated occipital mass, which was erroneously treated as a pyogenic granuloma. Imaging performed before a planned surgical resection detected an underlying intraoccipital dermoid with a sinus tract to the skin surface and extension into the posterior fossa. This case highlights the value of high-resolution computed tomography imaging for depiction of anatomic details and the value of magnetic resonance imaging for differential diagnosis and surgical management...

PURPOSE: Benign masses of the eyebrow and forehead are common in pediatric patients and can result in facial asymmetry, discomfort, or super-infection. Excision is classically conducted via an incision directly over the mass, which can produce sub-optimal cosmesis. Recently, an endoscopic approach using pediatric brow-lift equipment has been adopted. We reviewed our center's experience with endoscopic removal of benign facial lesions and compared these cases with an equivalent series of open cases...

BACKGROUND: The management of dermoid cysts can be tedious as they have a tendency to recur, and respond poorly to chemotherapy and radiation. Management is especially difficult for tumors involving highly eloquent areas such as the conus medullaris. OBJECTIVE: We aim to provide a summary of the pathology, clinical presentation, and operative management strategies of dermoid cysts involving the conus medullaris. METHODS: Two clinical cases of dermoid cysts of the conus are presented, as well as a commented surgical video...

The purpose of this study was two-fold, first to investigate the association between endometriosis and the risk of benign gynecologic tumors and, secondly, to evaluate the distribution of endometrioma and ovarian cysts in women with endometriosis. The medical and pathological reports of 1,000 women with endometriosis were retrospectively reviewed. The incidence of ovarian cysts, uterine leiomyomas and adenomyosis, as well as the side of ovarian cysts were further compared. A total of 295 cases of endometriomas, 172 cases of adenomyosis, 173 cases of ovarian cysts and 89 cases of uterine leiomyomas were confirmed histologically in patients with endometriosis...

Goldenhar´s syndrome (GS) also known as oculo-auriculo-vertebral spectrum (OAVS) is a relatively rare condition. GS is of multifactorial etiology that includes environmental and/or genetic factors, in addition to teratogens that disturb the blastogenesis. A 5-year-old girl from Saudi Arabia, was a member of dizygotic twins conceived by assisted reproductive technology (ART), and born with features of GS. She had asymmetrical face, cleft lip and palate, right microphthalmia and microtia. Radiological imaging showed right maxillary and mandibular bone hypoplasia, asymmetrically enlarged parietal foramina, a persistent midline occipital foramen, abnormal bone arising from occipital bone, extending along tentorium cerebelli, and a lipoma at the right tentorium cerebelli...

Both lipomas and dermoid cysts of the cerebellopontine angle are rare tumors. These tumors differ in their embryological origin but share similar features on imaging. Both of these congenital lesions can be found in the cerebellopontine angle (CPA), and symptomatic clinical presentation is dictated by the location of the lesion. This paper demonstrates a unique case in which a CPA lipoma was misidentified as a dermoid cyst, leading to surgical intervention. Further, the paper provides a literature review of CPA lipomas and dermoid cysts to aid readers in further differentiating between these two unique tumors...

Dermoid cyst is an example of choristoma (i.e., tumors that originate from aberrant primordial tissue which result in normal appearing tissue in an abnormal location). This particular type of cyst is formed at the site where 2 suture lines of the skull close during embryonic development, and during this time, dermal or epidermal elements are pinched off which later convert to form cysts. Approximately, 50% of these tumors that involve the head are found in or adjacent to the orbit. This article presents a similar case of the orbital dermoid cyst with its management and also a review on other varieties of dermoid cysts of the head and neck region...

Orbital hypertelorism is an increased distance between the bony orbits and can be caused by frontonasal malformations, craniofacial clefts, frontoethmoidal encephaloceles, glial tumors or dermoid cysts of the root of the nose, and various syndromic or chromosomal disorders. We report a series of 7 cases of hypertelorism that were treated in our hospital. The underlying causes in our series were craniofacial clefts 0 to 14 (4 cases), craniofacial clefts 1 to 12 (1 case), and frontonasal encephalocele (2 cases), all congenital...

Purpose: To present a young female patient with left anterior orbital leiomyoma that originates from the supraorbital neurovascular bundle. Case presentation: A 41-year-old female patient was admitted to our clinic with a complaint of swelling of the left upper eyelid. Based on the ophthalmological and imaging assessments, the excisional biopsy with the preliminary diagnosis of dermoid cyst was planned. The histopathological and immunohistochemical examinations of excised sample revealed surprisingly that the tumour was a leiomyoma...

Frontorhiny is one of the two forms of mid-facial malformations characterized by ocular hypertelorism, wide and short nasal ridge, bifid nasal tip, broad columella, widely separated nares, long and wide philtrum and V-shaped hairline. Sometimes these phenotypes are associated with ptosis and midline dermoid cysts. Frontorhiny inherits in an autosomal recessive pattern. Sequence variants in the Aristaless-like homeobox 3 (ALX3) gene underlying frontorhiny have been reported previously. Here, in the present study, we have investigated four patients in a consanguineous family of Pakistani origin segregating frontorhiny in autosomal recessive manner...
