pediatric cervicofacial actinomycosis is a rare occurrence consequent to dental infections and manipulations or maxillofacial trauma. the clinical presentation ranges from multiple draining sinuses to swellings resembling tumors and cysts. the present unusual case had congenital dermoid cyst of mid upper lip with actinomyces israelii infection identified on microscopy, culture, and histopatholo...

A 21-year-old male presented with a pineal dermoid cyst manifesting as headache and diplopia. He had undergone gross total removal of a pineal mature teratoma 18 years before and had done well until recently. Diffusion-weighted magnetic resonance imaging showed a region of high signal intensity due to a round mass in the pineal region and extending into the trigone of the right lateral ventricl...

A 39-year-old man developed dizziness and diplopia. Examination showed medial gaze palsy of the right eye. He had no headache, vertical gaze palsy, or skew deviation. A CSF examination was not performed. MRI (figure) showed cystic mass and acute infarction. After 7 days heparization, the mass was removed by surgery and pathology confirmed the dermoid cyst. After operation, the neurologic abnorm...

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...

Dermoid cysts of the head and neck are rare congenital benign tumors. According to the literature they represent about seven percent of all dermoids and less than one percent of all intracranial neoplasms. Extradural dermoid cysts are very rare. We report a case of intracranial extradural dermoid cyst of mastoid bone. We believe that this is the second documented extradural dermoid cyst, the fi...

congenital cystic lesions of the pancreas are rare findings. furthermore, dermoid cyst of the pancreas is exceptionally uncommon. a review of the world literature showed that only 18 documented cases of dermoid cyst of the pancreas were reported so far. the pre-operative evaluation of this lesion is rather questionable, with definitive diagnosis taking place intra-operatively. herein, we presen...

A congenital cystic mass was detected at the suprasternal notch of a seven-month-old male infant. After radiologic examinations including ultrasonography, computed tomography, and magnetic resonance imaging, the cyst was excised and diagnosed as a dermoid cyst. Dermoid cysts of the head and neck are rare lesions, but a midline location is characteristic for these congenital masses. To our knowl...

Dermoid cysts arising from the head and neck region are rare, slow-growing, and well-circumscribed neoplasms. Symptoms are non-specific and usually related to the size and the location of the lesion. A dermoid cyst of the epiglottis is extremely rare. To the best of our knowledge, only one case has been previously reported in the English literature. In this study, a case of a dermoid cyst arisi...

INTRODUCTION In this report we discuss the etiology, common locations, diagnostic approach, and treatment of a dermoid cyst. CASE PRESENTATION A 22-year-old man arrived at the emergency department complaining of submental fullness, an increase in snoring, choking, gagging, and difficulty breathing. The patient was taken to the operating room for a complete resection of a large dermoid cyst th...

Nasal dermoid sinus cysts are the most common congenital midline nasal lesion, accounting for 1% to 3% of all dermoid cysts, and 4% to 12% of all head and neck dermoids. Selection of the appropriate reconstruction technique, after dermoid resection, is important for treatment. Here we describe the successful management of a case with a nasal dermoid sinus cyst using an open rhinoplasty approach...
