Background: Non-midline supratentorial dermoid cyst with dermal sinus tract has been rarely reported especially in adults. We recently experienced a noteworthy patient with frontotemporal dermoid cyst with incomplete dermal sinus tract. Case Description: A 43-year-old female presented with recurrent subcutaneous mass in the left superolateral orbital region. She had a history of active bronchial asthma, which precluded her from contrast-enhanced imaging studies. Plain imaging studies showed a subcutaneous mass which was continuous with an intrasylvian fissure mass by a tract in the sphenoid ridge and the lesser wing of the sphenoid bone. Frontotemporal craniotomy was performed to reset the mass and the tract. Intraoperative finding showed no intradural tumor components. Extradural component was carefully removed focusing attention on the frontal branch of the facial nerve. The pathology was consistent with dermoid cyst and dermal sinus tract. Postoperatively, she had mild facial palsy of the corrugator supercilii (House and Brackmann Grade II). She was discharged home with modified Rankin scale 1. Conclusion: Dermoid cyst needs to be included in the differential diagnosis of adult-onset subcutaneous mass in the frontotemporal regions. After thorough imaging studies for the presence and extent of the sinus tract, the symptomatic lesion should be excised completely once and for all.

Abstract Prevotella species are gram-negative anaerobic commensal bacteria of the oropharynx, which frequently cause periodontal disease but are otherwise rarely implicated in serious bacterial infections. Cranial dermoid cysts are benign neoplasms that grow along the planes of the embryonic neural tube closure. In infants, they most commonly present in frontal locations, including periorbital, nasal, and within the anterior fontanelle. Although dermoid cysts are slow growing, usually uncomplicated, and easily treated definitively with surgical excision, cranial cysts located on the midline are associated with a higher risk for persistent dermal sinus tract with intracranial extension of the tumor. We describe a case of a 10-month-old male patient with an occipital midline dermoid cyst with intracranial extension, infected with Prevotella melaninogenica, and complicated by intracranial abscess formation and meningitis.This case highlights two unusual disease entities: the uncommon occipital location of a dermoid cyst, and complications of that cyst caused by a serious bacterial infection with a normal oral flora. We discuss the recommendation for neuroimaging prior to surgical excision of a midline dermoid cyst, given the risk for dermal sinus tract with intracranial communication. We also discuss potential mechanisms for bacterial inoculation of this cyst with Prevotella melaninogenica. This pathogen has not previously been reported as a complication of dermoid cysts.

Dermoid cysts, encephaloceles, and dermal sinus tracts represent abnormalities that develop during the process of embryogenesis. The elucidation of the precise timing of formation for these malformations has remained elusive at the molecular level of study. Yet, clinical experience has demonstrated that these malformations do not all occur in the same patient, suggesting a shared pathway that goes awry at distinct points for different patients, resulting in 1 of the 3 malformations. Herein the authors describe a case in which all 3 malformations were present in a single patient. This is the first description in the English literature of a sincipital encephalocele occurring with a dermoid cyst and a dermal sinus tract.

Background:Cranial dermal sinuses are rare and occur most frequently in the posterior fossa and along the midline. Likewise, supratentorial dermoid cysts are very uncommon.Method:We report a unique case of an adult female patient with both a supratentorial dermoid cyst and an incomplete dermal sinus tract.Results:The patient is a 31-year-old female, who presented with a new onset complex partial seizure. Neuroimaging and surgery revealed a right superior temporal dermoid cyst with an associated dermal sinus tract. Furthermore, the dermal sinus tract was incomplete and had no cutaneous manifestations.Conclusion:We present a rare patient with an off midline supratentorial dermoid cyst associated with a uniquely incomplete cranial dermal sinus tract. The dermal sinus tract involved the bone, dura and intradural compartment, without involving the overlying skin. This represents a novel variant in the spectrum of cranial dermal sinus abnormalities.

Object The goal of the present study goal was to systematically confirm the previously recognized nomenclature for tethering tracts that are part of the spectrum of occult spinal dysraphic lesions. Methods The tethering tract in 20 patients with spina bifida occulta underwent histological examination with H & E staining and epithelial membrane antigen (EMA) immunolabeling, and additional selected specimens were stained with Masson trichrome. Results All tethering tracts contained fibrous connective tissue. Four tracts were lined with epithelial cells and either originated within a dermoid cyst, terminated at a skin dimple/sinus opening, or had both of these characteristics. No tethering tracts exhibited EMA positivity or meningeal elements. Although all tethering tracts originated in juxtaposition to the spinal cord, their termination sites were variable. Conclusions Based on histological findings and presumed embryological origin, the authors broadly classified tethering tracts terminating within the dura mater, epidural space, or lamina as “short tethering tracts” (STTs). The STTs occurred mostly in conjunction with split cord malformations and had a purely fibrous composition. Tethering tracts terminating superficial to the overlying lamina were classified as “long tethering tracts” (LTTs), and the authors propose that these are embryologically distinct from STTs. The LTTs were of two varieties: epithelial and nonepithelial, the former being typically associated with a skin dimple or spinal cord (epi)dermoid cyst. In fact, analysis of the data suggested that not every tethering tract terminating in or on the skin should be classified as a dermal sinus tract without histological confirmation, and because no evidence of meningeal tissue–lined tracts was detected, the use of the term “meningocele manqué” may not be appropriate.

Spinal epidermoid cyst is a rare entity. It may be congenital with associated spinal dysraphism such asspina bifida ,dermal sinus tract and other neural tube defects or acquired due to repeated lumbar puncture and trauma. Congenital spinal epidermoid cysts without spinal dysraphism are rare. Here we are reporting a rare and interesting case of thoracic extramedullary intradural epidermoid cyst with no associated features of spinal dysraphism or history of iatrogenic trauma in a young male patient.
