To the Editor: Epidermoid cyst, was first described by an artist in a French medical school in 1807, [1] is a kind of congenital disease characterized by a stratified epithelial capsule and laminated keratin debris contents. It accounts for approximately 1% of all intracranial tumors and commonly locates in the cerebellopontine angle, parasellar region, and the fourth ventricle. Cerebrospinal f...

A Case report about an intramedullary epidermoid cyst and its association with an arrested ascent of the spinal cord, concomitant the neurological deficits, the surgical treatment and the clinical progress after one year. Epidermoid cysts are rare in the spinal cord, less than 1% of all spinal tumors. A 40-year-old woman described hypesthesia in the right left foot and back pain since one year....

Definition An epidermoid cyst may be defined as a cyst arising from ectodermal cell-rests, and in particular from epidermal primordia. In the literate, varieties of cysts from dermoids, both sequestration and implantation types to cholesteatomas, have been included under the heading of epidermoids. Some authors have included wens or sebaceous cysts in the classification of epidermoids. In a sim...

Spinal epidermoid and dermoid tumours are rai neoplasms (Russell and Rubinstein, 1963). Recentl: the epidermoid type of tumour has been reporte relatively often in patients who have had multip] lumbar punctures (Blockey and Schorstein, 1961 Choremis, Economos, Papadatos, and Gargoula 1956), and has been thought to have arisen fror implanted fragments of epidermis carried into th subarachnoid sp...

Testicular epidermoid cysts are a rare cause of testicular pathology. No cases of recurrence or metastasis have been reported in the literature. As a result, inguinal partial orchiectomy with frozen section has recently become standard treatment. A 43-year-old male presented with right testicular discomfort and the presence of mass. Right inguinal partial orchiectomy with frozen section was per...

Intradural extramedullary epidermoid (EC) cysts are uncommon (0.2-1%). Acquired tumors appear more frequently as a late complication of lumbar punctures (40%). The authors present three cases of epidermoid cysts of the cauda equina which were surgically treated in their department during the past five years. All three had suffered lumbar punctures for rachianesthesia 6-9 years prior to their pr...

Epidermoid cyst is of common occurrence in other parts of the body, but has rarely been described in the presacral space [1]. It is a benign congenital lesion, mostly seen in middle-aged females and is usually asymptomatic. Pathologically, it contains a thin wall lined by stratified squamous epithelium with a mixture of desquamated debris, keratin, cholesterol, and water. From the development a...
