This one is characterized by the presence of a squamous stratified epithelium with cutaneous remnants. It may occur in any part of the body, however their frequency in the ENT sphere is relatively scarce. Seven per cent (7%) only of epidermoid cysts occur in the cervico-facial area, 1.6% of which locate at the floor level. When they are located submandibular, they can pose diagnostic difficulties and look like a tumour of the submaxillary gland. We report two cases of epidermoid cyst of the floor. Both patients suffered from swelling of the submandibular gland. Magnetic Resonance Imaging was not requested due to lack of resources. However, surgery allowed in both cases the excision of a cyst next to a normal submandibular gland. Patients did well post operatively.展开更多

Some may attain great size. Correct radiological assessment and complete removal of the tumor and its capsule are essential for adequate surgical treatment and good long-term prognosis. We report two cases of intradiploic epidermoid cysts of the skull, with giant and CT-hyperdense lesions with extra and intracranial extension, and analyze the clinicopathological and imaging features and treatment of these lesions in the light of the most important published data.展开更多

Mainly reported in adulthood, it is fought to be a posterior fossa benign tumor. In this paper, we talk about a 64-year-old woman, following up for Parkinson’s disease presented in our department for 7 months’ history of headache and gait disturbance. MRI showed a right cerebellopontine angle (CPA) heterogeneous unlimited tumor mimicking an epidermoid cyst. She underwent a lateral suboccipital craniectomy procedure that permitted obtaining the whole gross total resection of this tumor. The histopathological diagnosis was a cerebellar liponeurocytoma. She was discharged from hospital the 8th day after surgery and was free of symptoms since 5 years.展开更多

Concerns about overwhelming postsplenectomy sepsis have led to the development of splenic preservation procedures in the treatment of cystic diseases of the spleen. Better understanding of the splenic segmental anatomy and advances in laparoscopic skills has made laparoscopic partial splenectomy a preferred treatment for splenic cysts while preserving splenic function. We reported a case of a 30-year-old male patient with a large epidermoid splenic cyst managed successfully by laparoscopic partial splenectomy. The patient recovered well after operation and was asymptomatic on a follow-up of 1 year with no recurrence on ultrasonography and a normal platelet count. Laparoscopic partial cystectomy is an acceptable procedure for the treatment of splenic cysts which locate in the pole of spleen. On the one hand, it cures the disease preserving the splenic tissue without risk of bleeding or recurrence; on the other hand, this minimally invasive technique induces a reduced hospital stay and a more rapid recovery.展开更多
