Epidermoid cysts are rarely detected malformations in the oral cavity. Their development sites are the sublingual, submaxillary, and submandibular spaces. In this paper, we report a three-month-old infant who was admitted to our hospital due upper lip swelling. Magnetic resonance imaging showed that she had a two-centimeter cystic lesion and fusion defects of orbicularis oris muscle. The cyst w...

Two patients with recurrent aseptic meningitis are reported. Intracranial epidermoid tumors were eventually found in both patients. CSF changes in our first case with an epidermoid tumor were similar to those reported in Mollaret's meningitis, with an initial polymorphonuclear pleocytosis early in each attack, followed by a lymphocytic predominance several days later. Large cells which proved t...

Epidermoid cysts are relatively common entities, but we present a large cyst which occurred almost directly over the olecranon, a previously unreported location. The 31 year old male patient had a history of previous epidermoid cysts in the head/ neck and after en block excision there has been no recurrence at 4 years.

Mediastinal epidermoid cyst is a rare condition that is considered as a congenital disorder. Various manifestations from asymptomatic cases to serious symptoms may be found in these patients. However, some cases may be diagnosed incidentally. Here, we report an old man with recurrent pneumonia who demonstrated symptoms of respiratory distress and chest pain. The high resolution computed tomogra...

Acquired spinal epidermoid cysts are extremely rare. There are only a few reports on the formation of epidermoid cysts after lumbar puncture or spinal trauma. In this report, we present a patient who was diagnosed with epidermoid cyst after operation for spinal fracture. This 43-year old female suffered from progressively worsening low back pain radiating down the left leg four years after lumb...

Context An epidermoid cyst arising from intrapancreatic accessory spleen is rare. Herein, we report the patient who had an epidermoid cyst arising from intrapancreatic accessory spleen with typical imaging features, which was diagnosed by preoperative imaging studies and successfully treated with minimally invasive surgery. Case report A seventy-five-year-old male was referred to our hospital p...

BACKGROUND An epidermoid cyst is a common epithelial-lined cyst. There have been many studies on epidermoid cysts, but few focused on ruptured epidermoid cyst and its histopathologic characteristics. OBJECTIVE We evaluated the histopathologic differences between ruptured and unruptured epidermoid cysts, and their relationships. METHODS We retrospectively examined 359 excision biopsy specime...

PURPOSE To determine whether steady-state free precession sequences improve the MR visibility of epidermoid tumors in comparison with spin-echo images. METHODS Patients were four women and three men with epidermoid tumors in the subarachnoid spaces. MR was performed with a 1.5-T superconductive unit. For steady-state free precession imaging, three-dimensional Fourier transform fast imaging wi...

Dermoid cysts of the brain are not uncommon, and as many as 200 dermoid and epidermoid cysts found throughout the central nervous system have been reported by Rand and Reeves (1943). However, epidermoid and dermoid tumours of the spinal canal together with teratoid tumours, with or without communicating dermal sinuses, are of extreme rarity. Boldrey and Elvidge (1939) published a total of 43 ep...

introduction: epidermoid tumors comprise 1% of intracranial tumors. although reported, intraosseous epidermoid tumors are even more rare. cystic lesions of the petrous apex are uncommon and surgically challenging; the most rare pathology is presumed to be epidermoid.rncase presentation: this is a case of a 61-year-old woman with a large skull-base tumor extending inferiorly from the c1-c2 artic...
