Dermoid cyst (also called as ‘mature teratoma’) is a type of germ cell tumour. The word ‘teratoma’ derived from Greek work ‘teraton’ meaning monster. It was initially used by Virchow in 1863. term ‘dermoid cyst’ coined Leblanc 1831. majority dermoid cysts are unilateral with equal frequency both ovaries; moreover, bilateral tumours found approximately 10-12% cases and we presented two such ovary.

Dermoid cysts are rare developmental teratomatous lesions composed of ectodermally derived stratified squamous epithelium and mesodermally derived skin adnexal structures. Although several theories have been postulated, the pathogenesis of dermoid cysts and teratomatous lesions in general is unclear. Ovary is the most frequent affected organ, but it can occur in the mediastinum retroperitoneum,...

Ovarian dermoid cysts are one of the most common benign neoplasms in women. Rectal fistula formation due to an ovarian dermoid cyst, particularly a benign dermoid cyst, is extremely rare. A 17-year-old girl with symptoms of lower abdominal pain, passage of sebaceous materials in the stool, and hematochezia was found to have an 11-cm dermoid cyst complicated with a rectal fistula formation. Lapa...

Objective: The efficiency and safety of laparoscopic surgery in the management of ovarian dermoid cyst. Material and Methods: Our study included forty patients with diagnosis of unilateral or bilateral dermoid cysts between August 2006 and May 2008 underwent laparoscopic removal of dermoid cysts. All cases were performed at department of obstetrics and Gynecology, women's health centre, Faculty...

Dermoid cysts are benign and congenital ectodermal inclusions. Their occurrence in an intracranial location is quite rare. They constitute 0.1 to 0.7% of all intracranial tumors. Their occurrence in the fourth ventricle and their multicentric feature are extraordinary. A 12-year-old boy was admitted to our clinic with a dermoid cyst with sixth cranial nerve involvement. He had symptoms of incre...

Supratentorial dermoid cysts are uncommon to develop in the cavernous sinus. We present a ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa. The patient was a 32-year-old female who complained occipital headache, blurred vision, and tinnitus over 4 years. Brain magnetic resonance (MR) imaging revealed an enhanced tumor in the right cavernous sinus extending into th...

Ovarian dermoid cysts are made up of solid, cystic and fat tissue. These components give rise to characteristic sonographic features such as a fat-fluid level, dermoid mesh and tip of the iceberg sign. The presence of two or more of these typical features can be used to confidently diagnose a dermoid cyst on ultrasound. This 41-year-old woman with a known cystic lesion on her right ovary which,...

Dermoid cysts are malformations that are rarely observed in the oral cavity. Histologically, they can be further classified as epidermoid, dermoid or teratoid. We report a case in which a 25-year-old man developed an epidermoid cyst presenting as a large sublingual swelling causing speech and swallowing difficulties. The differential diagnosis for dermoid cysts includes infections, tumours, muc...

purpose:  to report a patient with pretarsal dermoid cyst. patient and findings: a 2.5-year-old girl presented with a pretarsal upper lid mass and underwent excisional biopsy. a 1.0´1.0 cm cystic mass attached to upper lid tarsus was completely excised. pathologic study of the specimen revealed a dermoid cyst. conclusion: although pretarsal dermoid cyst is rare; it should be considered in all c...

Dermoid cyst is a rare but well recognised cause of a mass in the abdomen. As a cause of a palpable mass in the right iliac fossa, dermoid and epidermoid cysts of the caecum have hitherto been described. We here report a case of a dermoid cyst arising from the vermiform appendix.
