Holmes' tremor is characterized by a combination of rest, postural, and intention tremor. Tremor is predominantly proximal and more severe during posture; however, the tremor frequency is usually <4 Hz on surface electromyography. We report Holmes' tremor in a patient secondary to cerebellopontine angle epidermoid cyst.

BACKGROUND: Ecchordosis physaliphora (EP) is a benign notochordal remnant, which is usually asymptomatic. Herein, we report a case of symptomatic large EP mimicking an epidermoid cyst. CASE DESCRIPTION: A 44-year-old female presented with right facial dysesthesia. Brain magnetic resonance imaging (MRI) showed a mass with a diameter of 3.2 cm that was hypointense on T1-weighted images (T1WI), hyperintense on T2-weighted images (T2WI), iso-to-hyperintense on diffusion-weighted (DW) images, and hyperintense on apparent diffusion coefficient (ADC) map (1...

Oral foregut duplication cysts are extremely rare lesions with approximately 57 cases reported. They are congenital cysts, located in the anterior or ventral tongue, and occur predominantly in males. They are lined by one or more types of epithelia which is limited to gastric, intestinal or respiratory epithelium. The differential diagnosis includes lymphangioma, hemangioma, ranula, epidermoid cyst, teratoma and less likely a malignant process.

The aim of the present study was to evaluate the value of identifying fluid-fluid level via preoperative magnetic resonance (MR) images in differentiating pituitary adenomas from craniopharyngioma, Rathke's cleft cyst (RCC), and other cystic sellar-suprasellar lesions. The data of 293 consecutive patients who underwent surgery for sellar-suprasellar lesions between July 2010 and December 2012 was retrospectively reviewed, and a total of 133 cystic cases were included in the present study. MR images and pathological features of all subjects were examined...

Testicular seminoma is the most common malignant tumor of the testis. It classically manifests as a painless mass. Radiologic evaluation with high-frequency ultrasonography (US) is critical for diagnosis. Seminomas are usually homogeneously hypoechoic masses at US. In challenging cases, magnetic resonance (MR) imaging may help confirm that a mass is intratesticular and provide data for local staging. Computed tomography (CT) provides valuable information for staging, including the presence and size of retroperitoneal lymph nodes...

INTRODUCTION: Epidermoid cyst is a common clinical entity and it can occur anywhere in the body. But its occurrence and huge size in the breast is very rare and more liable to develop complications, including malignant transformation. PRESENTATION OF CASE: We present here an unusual case of a giant epidermoid cyst in the breast, which is about 7cm in greatest dimension. After proper preoperative diagnosis by clinical, imaging and histopathological findings, it was managed by total excision...

Accessory spleens (ASs), ectopic splenic tissue at intrapancreatic and extrapancreatic sites, rarely contain epidermoid cysts. Our aim was to analyze the incidence of epidermoid cysts in ASs and perform an immunohistochemical analysis of its epithelial lining. We included in the study 148 ASs from 135 patients, for which pathological data were available. Eleven were intrapancreatic ASs (IPASs) and 137 were extrapancreatic ASs (EPASs). Six of the eleven (55%) IPASs contained epidermoid cysts, but they were not detected in EPASs...

Xanthogranulomatous orchitis has been reported to be an extremely rare inflammatory change caused by infection and is difficult to distinguish from testicular tumor. We report a 28-year-old man who presented with a lump in his left testis after a blunt testicular trauma. Based on a series of imaging tests, we suspected benign tumor such as epidermoid cyst and performed tumor enucleation (testis-sparing surgery) on the patient. Histopathological findings showed xanthogranulomatous orchitis. It is assumed that xanthogranulomatous orchitis in this case was caused by blunt testicular trauma and this is the first successful case of xanthoglomatous orchitis in salvaging the testis...

BACKGROUND: Intrinsic brainstem epidermoid cysts are rare, benign, slow growing lesions. Their eloquence preclude complete excision, however subtotal resection will often result in prolonged or sometimes permanent relief of presenting symptoms and signs. We describe an unusual case and review the literature of this pathology in the paediatric population. CASE DESCRIPTION: We report an intra-axial pontine epidermoid cyst in a 2-year-old girl who presented with developmental delay, multiple cranial nerve palsies and pneumonia...

Cholesteatoma is a well demarcated, non-neoplastic, temporal bone cystic lesion with extensive keratinisation. Keratoma and epidermoid cyst are other possibly more accurate names suggested to describe the same. It can be classified as congenital or acquired. Its management is often complicated by its tendency to recidivism/recurrence. Long standing cholesteatomas can be a precursor for squamous cell carcinoma. We hereby present a case of giant cholesteatoma in a 45-year-old female with radiological involvement of the left temporal region, periauricular region and infratemporal fossa with lytic destruction of left middle ear ossicles, mastoid and squamous part of temporal bone with intracranial extension...

Choledochal cyst is a cystic dilation of the biliary tree that can increase the risk of malignancy in bile ducts and the gallbladder. These are usually lined by bile duct epithelium, which may undergo intestinal and squamous metaplasia. This is the first report of clinically diagnosed type II choledochal cyst that is entirely lined by metaplastic stratified squamous epithelium, unlike most other cysts, which are histologically lined by bile duct epithelium. This observation can potentially explain the underlying pathogenic mechanism of rare reports of squamous cell carcinomas arising in bile duct systems...

Epidermoid and dermoid cysts account for <0.01% of all oral cavity lesions with dermoid cyst which is twice as common to epidermoid. Epidermoid cysts are benign lesions that occur rarely in children. They usually present early in life as an asymptomatic mass. The treatment option is surgical and intraoral or extraoral approaches can be performed according to the localization and size of the mass. This report presents an 11 year old child with a sublingual epidermoid cyst treated extraorally.

Although presacral developmental cysts, including epidermoid cysts, are relatively rare diseases, an intrapelvic mass found for the first time in early pregnancy should be followed-up with the possibility of presacral developmental cysts in mind to be alert to the signs of local infection and malignancy. We treated a pregnant patient with presacral cystic disease. During pregnancy, percutaneous fenestration was performed because the cyst caused severe compression symptoms and complicated bacterial infection...

Epidermoid cysts are classical tumors in neurosurgery, but spinal locations are rare and intramedullary locations represent only approximately 80 cases in the literature. Intramedullary epidermoid cysts arise from ectodermic tissue inclusion during neural tube closure. Intramedullary epidermoid cysts are more frequent in young patients and in a thoracic location. We report the case of a 61-year-old patient consulting for bilateral asymmetrical progressive paraparesis and proprioceptive ataxia revealing a T3-T4 exophytic medullar epidermoid cyst...

We report an unusual complication following placement of a thoracic epidural catheter in a patient that had undergone surgery for pulmonary metastases of a malignant melanoma. The intra- and postoperative course was initially without complications. At 2 days, there was a small, conspicuous swelling above the site of epidural puncture, which was neither reddened nor painful. No neurological deficits were observed, and the patient explained that he had been aware of the swelling for more than 6 months; thus, the epidural catheter was not deemed to be responsible...

Dermoid cyst is a congenital lesion that arises due to embryogenic impairment. It accounts for less than 0.3% of all intracranial masses. Herein we report a 30-year-old male who presented with a short history of headache and behavioral disorder. Physical and radiological examination diagnosed it to be a lipoma/epidermoid arising from corpus callosum. The lesion was removed endoscopically and histopathologic examination was performed which confirmed it to be a dermoid cyst. Rarity of the lesion and difficulty in pre-operative diagnosis prompted us to bring forward this case report...
