Dysontogenetic cysts, commonly referred as dermoid cysts or teratoid cysts, are hamartomas which may contain various derivatives of endoderm, mesoderm and ectoderm7. The majority of cases is reported in the midline of the body and especially in testes and ovaries. The most common site in the head and neck region is the lateral eyebrow, the so-called angular dermoid, and approximately 6.5% of th...

Dermoid cyst can also be seen head and neck region although it is generally seen in testis and ovary. The most common location in the head and neck region is the external third of the eyebrow. Sublingual location is very rare. Surgical treatment is by enucleation via intraoral or extraoral approach. We present herein a case of giant sublingual dermoid cyst, origin from the mandibular symphisis ...

We report a 16-year-old girl who had stunted growth and primary amenorrhea presenting with headache and vomiting. MRI of brain showed posterior fossa dermoid cyst with hydrocephalus and empty sella. Growth hormone (GH), Leutinizing hormone (LH) and Follicular stimulating hormone (FSH) were grossly reduced on endocrinological work-up. She underwent suboccipital midline cranie...

Intracranial dermoid cysts are rare tumors derived from ectopic epithelial cells. They are slow-growing benign entities, but can cause significant morbidity through compression of neurovascular structures and, rarely, rupture into the subarachnoid space. We present a rare case of a spontaneously ruptured intracranial dermoid cyst presenting as new onset seizures due to chemical meningitis cause...

Intracranial dermoid tumors represent a rare clinical entity accounting for 0.1-0.7% of all intracranial tumors. Their location in the posterior fossa is uncommon. We report a 16-year-old male patient who presented with clinical signs of increased intracranial pressure and cerebellar symptoms. The CT scan revealed a median cystic lesion of the fourth ventricle causing an active triventicular hy...

This case report presents the findings of significantly large sized (> 8 cm) symptomatic unilateral cystic teratomas in two perimenopausal patients in remote Nepal. Ovarian dermoid cysts consist of cystic, solid and fat tissue. Traditionally, cells differentiate along the various germ lines, essentially recapitulating various body tissues. The characteristic sonographic features include a dermo...

Dermoid cysts are developmental tumours that develop from germ cells displaced between the 3rd and 5th week of embryogenesis. Although dermoid cysts are known to be the most common scalp swellings; cystic congenital inclusion dermoid of the anterior fontanelle is a very rare scalp swelling. It is a benign, slow-growing, non-tender, soft swelling which is covered with intact skin. Ruling out int...

Laparoscopic-assisted ovarian cystectomy with exteriorization is a minimally invasive procedure. However, applicability of this procedure for transumbilical laparoendoscopic single-site (LESS) surgery is not well established. Herein, we describe our initial experience with isobaric (gasless) LESS-assisted extracorporeal cystectomy in management of selected adnexal tumors. Of 17 consecutive adne...

Intra-parotid dermoid cysts are extremely rare. Clinically, they present like any other parotid lump and pre-operative diagnosis is rarely possible. A 62 years old Caucasian man presented with a painless lump in his right parotid region. The Magnetic Resonance Imaging (MRI) scan revealed a 3 x 3 cm mass in the parotid tail. Cytological examination was unhelpful. The patient underwent successful...

We present a very rare case of malignant transformation of a benign mature cystic teratoma. The pathology report revealed malignant transformation of both the epithelial and sarcomatous elements of a benign dermoid cyst. To the best of our knowledge, this appears to be the third case of a malignant fibrous histiocytoma and a squamous cell carcinoma developing from a mature cystic teratoma. Mali...
