Dermoid cysts are rare congenital intracranial tumors. Among these tumors, extradural localization is extremely rare. We report a patient with an extradural dermoid cyst of the right parasellar region, causing right visual disturbance. Computed tomography revealed a hypodense mass lesion with rimlike calcification at the right parasellar region, accompanying marked erosion of the adjacent skull...

Introduction: Intracranial dermoid cysts are rare congenital lesions that can rupture and disseminate intracranially. We present a unique case of a ruptured dermoid cyst leading to blockage of ventriculo-peritoneal shunts. Case Report: A 19-year-old female presented with clumsiness, gait disturbance and occipital headache. Examination revealed an ataxic gait, positive Romberg’s sign, lateral ga...

Dermoid cysts are uncommon developmental anomalies that rarely occur in the oral cavity. Here, we report a case of a dermoid cyst at the midline of the floor of the mouth and evaluate the density of Langerhans cells in the epithelium lining of this dermoid cyst. A 7-year-old girl came to the dental department of our hospital for treatment of a sublingual swelling detected when she wasw2-years o...

A 9-month-old boy presented with a swelling in his left temporal area first noted by his mother 2 weeks prior to admission. Initially, the mass was soft and tender and the overlying skin was erythematous. Subsequently it enlarged and became firm and nontender. On physical examination, a firm, nontender 3 x 1 cm mass was palpated in the left temporal area, and a small black spot was noted on the...

Benign cystic teratoma (dermoid cyst) was managed laparoscopically in 25 cases (16 cyst excisions and 9 oophorectomies). Surgical procedures to avoid spill during ovarian cystectomy and oophorectomy were developed (14 cases). This series demonstrates a gradual evolution in surgical technique. Surgical outcome was good in all cases, complications were rare, and the procedure required a hospital ...

the occurrence of epidermoid and dermoid cysts in the oral cavity is extremely rare accounting 0.01% of all cysts. in our case report we hereby present a large epidermoid cyst in the floor of mouth imitating a plunging ranula. a 26-year-old female reported to us with a complaint of a swelling below the tongue since 2 year. on examination there was a swelling in the left side of the floor of the...

Splenic cysts are rare entities and are classified as true cysts or pseudocysts based on the presence of an epithelial lining. Congenital nonparasitic true cysts can be epidermoid, dermoid, or endodermoid, present at a young age, and are commonly located in the upper pole of the spleen. Surgical treatment is recommended for symptomatic, large (more than 5 cm), or complicated cysts. Depending on...

The cell of origin of the five subtypes (I-V) of germ cell tumors (GCTs) are assumed to be germ cells from different maturation stages. This is (potentially) reflected in their methylation status as fetal maturing primordial germ cells are globally demethylated during migration from the yolk sac to the gonad. Imprinted regions are erased in the gonad and later become uniparentally imprinted acc...
