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...

Epidermoid cysts are notorious for their propensity to sneak into deep recesses between cranial nerves in the posterior fossa. Attempts to achieve complete excision using ordinary instruments when tempted by the seeming ease of dissection is known to cause unacceptable deficits. The Xomed monopolar stimulator electrode probe of the nerve integrity electromyography monitor has several advantages when used as the primary dissection tool for deep-seated epidermoid cysts. Cerebellopontine angle epidermoid is the classical prototype of a strategically placed deep-seated epidermoid tumor...

Epidermoid cyst of the presacral space is a rare congenital lesion of ectodermal origin. Presacral epidermoid cysts have been previously reported in women, however are extremely rare in males. We report a case of presacral epidermoid cyst in a 55-year-old male who presented to our emergency department with acute urinary retention and history of chronic constipation. A non-contrast computed tomography scan was performed with suspicion of urolithiasis, which revealed a well circumscribed low attenuation presacral mass...

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...

Intraparenchymal epidermoid cysts (IECs) are rare lesions, thus the preoperative diagnosis and proper surgical management are still a challenge. We searched the database at our institution and performed a search of English literature in PubMed and Google Scholar. Keywords used were as follows: "intraparenchymal"; "intracerebral"; "intraaxial"; "epidermoid cyst"; "brainstem"; "cholesteatoma"; "pearly tumor". Only cases that were true intraparenchymally located and contained adequate clinical information were included...

PURPOSE: Small benign testicular masses are often misinterpreted as germ cell tumors, and immediate inguinal orchiectomy is performed. We aimed to analyse the diagnostic and therapeutic work-up of testicular masses in order to improve preoperative stratification algorithms. MATERIALS AND METHODS: We performed a retrospective, single-center analysis of 522 patients diagnosed with primary testicular masses of unknown malignant potential. RESULTS: 28 (5%) patients showed a primary benign tumor after resection: 9 (32%) Leydig cell tumors, 9 (32%) epidermoid cysts, 8 (29%) adenomatoid tumors and 2 (7%) Sertoli cell tumors...

BACKGROUND: The pineal gland has been demonstrated to be involved in the development of mood and psychotic disorders. However, few studies have looked at the relationship between pineal region tumors and psychiatric disorders. Intracranial epidermoid cysts usually arise in cerebellopontine angle area, and are extremely rare in the pineal region. The case of pineal epidermoid cyst presenting as schizophrenia has never been reported before. CASE PRESENTATION: We described the case of a 23-year old man who presented to hospital with symptoms suggestive of schizophrenia...

Milia are multiple, small, benign keratin-filled superficial epidermoid cysts which are classified as primary when they occur spontaneously or secondary when they result from skin trauma or disease. Multiple eruptive milia (MEM) refer to a condition characterized by a sudden eruption of a large number of milia. MEM may be familial, occur as part of a genodermatosis, or occur spontaneously when they are termed idiopathic. Idiopathic MEM are an exceedingly rare disease. We present the case of a 70-year-old Nigerian woman with idiopathic MEM...

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...

An epidermoid cyst is an infrequent entity among cysts found in the presacral region, frequently coexistent with a meningocele. Diffusion-weighted imaging is known to be a useful diagnostic measure for differentiating presacral epidermoid cysts. Here, we present a large but asymptomatic case found in the presacral region. Epidermoid cysts should be considered in patients with presacral cysts.

Epidermoid cysts are common benign lesions of hair-bearing, and less often glabrous skin. They can also occur in oral mucosa and internal organs. In case of cutaneous lesions, an epidermal punctum is a clinical diagnostic hallmark. The clinical presentation is variable leading to some differential diagnoses. Diagnosis of epidermoid cysts needs histopathological confirmation - not only of the potential of malignant transformation. The treatment of choice is surgery. We report a retrospective analysis of 2159 epidermoid cysts treated surgically...

INTRODUCTION: Testicular tumors in children have two peaks with different types of tumors; in the first 4 years of life a third to half are benign with increased risk of malignancy during puberty. The pathology of testicular tumors between these peaks, at the age of 5-12 years, is not known. We hypothesized that because of the low level of testosterone at this time, the incidence of malignant tumors is very low. OBJECTIVE: To compare malignancy risk of primary testicular tumors in children in the prepubertal period (5-12 years) compared with younger (0-4 years) and pubertal (13-18 years) children...
