Epidermoid cyst of intrapancreatic spleen is described but epidermoid cyst occurring in the pancreas itself is not documented. We report a 36-year-old man who presented with abdominal pain radiating to the back. On ultrasonography, a multilocular cyst was seen in the head of the pancreas. Fine-needle aspiration cytology suggested a diagnosis of epidermoid cyst, which [...]
Epidermoid and dermoid cysts are benign lesions encountered throughout the body, with 7% occurring in the head and neck area and 1.6% within the oral cavity. They represent less than 0.01% of all oral cavity cysts. The cysts can be defined as epidermoid when the lining presents only epithelium, dermoid cysts when skin adnexa are [...]
Intraspinal epidermoid tumors are rare. Most of these tumors occur spontaneously, while others may be acquired. Occurrence of epidermoid tumor following surgery for spinal dysraphism has been reported till 15 years from the day of surgery. We report here a case of Cauda equina syndrome due to intraspinal epidermoid tumor following 38 years of surgery [...]
A 65-year-old man with a history of alcoholism and smoking (60 pack-year), was admitted for exploration of a left submandibular tumefaction of one year’s duration. There were no similar cases in the family and no history of contact with tuberculosis. There was no history of surgical or radiological intervention in the submandibular region.
Physical examination revealed [...]
A 27-year-old man was referred for ultrasonographic (US) evaluation of a painless right testicular mass. The mass had been present for 3 years and had recently increased in size. Physical examination revealed no evidence of lymphadenopathy or gynecomastia. Laboratory test results, including levels of the tumor marker serum ß–human chorionic gonadotropin, were normal. The patient [...]
Epidermoid cyst in the spinal cord is a rare condition, constituting only 0.6–1.1% of all spinal tumors.1 The majority of spinal epidermoid cysts are subdural and extramedullary, while intramedullary localization is very rare.
Intramedullary epidermoid cyst is common in lumbosacral and thoracic regions; two frequent localizations are T4–T6 and T11–T12, while only three cases have been [...]
Discussion: There are congenital and acquired epidermoid cysts. Congenital type is a non-neoplastic inclusion of ectoderm during neural tube closure or formation of secondary cerebral vesicles. Acquired type is implanted epidermis, usually by nonstylet needle punctures (as in lumbar puncture). Grossly, it is a well-defined lobulated cystic lesion, which insinuates along CSF cisterns.
Cysts are harmless, sac-like growtsh in the deeper layers of the skin. They form from the lining of a hair follicle that gets blocked. It is not known why cysts appear, nor why some persons get many of them.
