Epidermoid cysts are benign slow growing extra-axial tumours that insinuate between brain structures, while their occurrences in intra-axial or intradiploic locations are exceptionally rare. We present the clinical, imaging, and pathological findings in two patients with atypical epidermoid cysts. CT and MRI findings for the first case revealed an intraparenchymal epidermoid cyst that demonstra...

Retrorectal epidermoid cyst is one of the developmental cysts which arise from remnants of embryonic tissues. We report a rare case of retrorectal epidermoid cyst, initially diagnosed as an ovarian tumor. Serum SCC value as tumor marker was elevated to the high level. Laparoscopy revealed ovaries, uterus and other pelvic organs were all normal. This tumor existed in the retroperitoneal cavity a...

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 preoperativ...

Epidermoid cysts have a benign etiology and can be either congenital, usually associated with malformations, or acquired, related to external events, even iatrogenic. As for their location, they are classified as extradural, intradural, extramedullary, intramedullary. Intradural intramedullary epidermoid quite uncommon, few cases reported in literature so far. Because of its slow growth, there ...

Epidermoid cysts are benign tumors originating from ectoderm remnants. Most epidermoid cyst cases are intracranial. Spinal epidermoid cysts are uncommon and most of the reported cases are in the thoracic and lumbar spine. Occurrence of intramedullary epidermoid cysts in the cervical spine is extremely rare. An 18-year-old male with a giant intramedullary tumor extending from the...

Congenital nasal epidermoid cyst without associated facial dysmorphism is an uncommon anomaly that is often asymptomatic. We report a case of occult nasal epidermoid cyst in a 12-year-old boy with initial nonspecific symptoms of fever, headache, abdominal pain, vomiting, and diarrhea. An enhanced magnetic resonance imaging (MRI) showed a cystic lesion in the frontal skull base with expansion of...

BACKGROUND Malignant squamous cell differentiation of an epidermoid cyst can carry a significantly poor prognosis and very little is known about this entity. CASE DESCRIPTION We present the case of a 35-year-old lady, with primary malignant squamous cell carcinoma (SCC) arising from a previously partially resected cerebellopontine angle epidermoid cyst almost 5 years after initial resection. ...

We report surgical treatment and radiotherapy of an extremely rare case of malignant epidermoid cyst located in cerebellopontine angle. MRI and CT demonstrated the lesion with partial enhancement and calcification. During operation, we found the tumor attached tightly to surrounding tissue. Finally we achieved near total resection of it. Histopathology confirmed the diagnosis of epidermoid cyst...

Ann Saudi Med 2006;26(6):477-479 Epidermoid cyst of the cecum is extremely rare. There have been only five reports of epidermoid cysts of the cecum in the English literature. The lesion has been reported in other internal organs in the epididymis, testis, spleen, accessory spleen and liver.1-9 I report the first case of epidermoid cyst of the cecum in the oldest patient reported thus far and di...

Epidermoid cysts are benign. slow-growing. congenital lesions (2. 4. 11). Craniocerebral epidermoid cysts constitute approximately 1% of all cranial tumors (1. 9). Calvarial intradiploic epidermoid cysts are very rare. In 1838. Miller was the first to describe a diploic epidermoid cyst of the skull (2). According to Ciappetta et al.. total 223 cases had been reported up to 1990 (2). Because of ...
