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...

BACKGROUND: Epidermoid cysts are benign lesions encountered throughout the body. Eighty percent of epidermoid cyst seen in ovaries and testicles, whereas in head and neck region they account for only 1.6-7.0%. 1.6% of epidermoid cysts occur in oral cavity and they account for 0.01% of all the oral cavity cysts. CASE DETAILS: Two case reports of epidermoid cyst has been discussed. One patient reported with well defined swelling in the right lower one third of the face, another one in the upper lip...

INTRODUCTION: Splenic tumors are rare and are either primary or secondary, benign or malignant. Most have none to minimal symptomatology and are found incidentally. Splenic cysts can be infectious, congenital, or traumatic. Epidermoid cysts and parasitic cysts are examples of primary cysts and usually have a classic presentation on imaging. Despite advanced imaging modalities and patient's clinical presentation, it can be difficult to diagnose an epidermoid cyst without histological examination...

BACKGROUND: Ischioanal fossa epidermoid cysts are uncommon masses of epithelial origin and are believed to be either congenital or the result of trauma. Surgical excision is preferred as opposed to incision and drainage because these masses may enlarge, recur, become infected, or undergo malignant transformation. CASE: This report describes a case of a 62-year-old woman who presented for evaluation of vaginal and perineal discomfort and fullness. Physical examination and computed tomography scan revealed a 7...

We report a case of Pseudomonas putida meningitis in a 26-year-old Nepalese man who was admitted to Hamad General Hospital with epidermoid cyst for drainage. Ommaya reservoir was placed into the cyst for drainage and externalventricular drainage (EVD) was performed. After four days, the patient was transferred to the ward in stable condition. His weakness resolved partially and headache severity decreased. After three days, the patient developed fever and headache severity increased with deterioration of consciousness level...

OBJECTIVES: Recently, we reported the tendency towards the spontaneous hemorrhage in both pre- and post-operative periods of patients with intracranial epidermoid cyst (EC). According to our experience this tendency of spontaneous hemorrhage was partly due to the pathologic blood vessels adjacent to the EC. This article was designed to testify this hypothesis. MATERIALS & METHODS: 23 removable pericystic or intracystic blood vessels from 17 EC patients were collected during surgery, and then were examined by transmission electron microscope...

Intracranial epidermoid cysts are benign lesions of epithelial origin that most frequently present with symptoms of mass effect. Although they are often associated with a high rate of residual tumor and recurrence, maximal safe resection usually leads to good outcomes. The authors report a complete resection of an uncommon pituitary stalk epidermoid cyst with intrasellar extension using a combined suprasellar and infrasellar interpituitary, endoscopic endonasal transsphenoidal approach. The patient, a 54-year-old woman, presented with headache, visual disturbance, and diabetes insipidus...

Median raphe cysts are congenital lesions that typically have a superficial appearance. We present a very unusual case of a deep perineal mass in a six-year-old boy. The lesion extends into the corpus cavernosum, suggesting that the anomaly was an early embryological event. Histopathological features are consistent with an epidermoid type of median raphe cyst.

Krishnan Ravindran, Te Whiti Rogers, Tanya Yuen, Frank Gaillard
White epidermoids are a rare variant of an intracranial epidermoid cyst that do not exhibit typical 'near- cerebrospinal fluid (CSF)' CT density or MRI intensity. Here, the authors present the case of a 58year old man with an acute onset of aphasia and altered consciousness, due to a large heterogeneous cranial mass in the left frontal region with unusual signal intensity. Subsequent histopathological analysis identified the lesion as an epidermoid cyst.

INTRODUCTION: We evaluate the clinical outcome of patients treated with conservative approach for small testicular masses (STMs). We analyzed the steps who brought to the selection of the therapeutic approach: starting from clinical presentation, through imaging and lab studies. METHODS: We considered 18 patients who underwent an organ-sparing approach for STMs from 2005 until 2014. The selection criteria were dimension of the mass and absence of clinical, laboratory and/or radiological malignancy suspicion...

We report a case of malignant transformation of an intracranial extradural epidermoid cyst into squamous cell carcinoma (SCC), that presented with cerebrospinal fluid (CSF) leakage at the time of recurrence. Intracranial epidermoid cysts are histologically benign and slow-growing neoplasms. They are congenital lesions that develop from ectodermal remnants during neuroembryogenesis. Malignant transformation of epidermoid cysts into SCC is very rare. Various clinical presentations of these tumors after malignant transformation are mentioned in the literature...
