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 are rare benign tumors that arise from ectopic epiblastic inclusions and account for 0.4% to 1.5% of all tumors. They are usually 1 to 5 cm in size and composed of a pasty semisolid material. The orbital dermoid cyst is the most common type. Dermoid cysts can also occur in the spinal cord, ovaries, and pancreas. We encountered a 24-year-old man with a dermoid cyst over the left sternoclavicular joint. He reported intermittent secretion of a white tofu-like exudate from an underlying congenital sinus tract since birth. The secretion had turned hemorrhagic for the last month and had been accompanied by progressive swelling and pruritus for 1 week. Ultrasonography and magnetic resonance imaging revealed characteristics of a dermoid cyst, and histopathological examination confirmed the diagnosis. The patient underwent surgical excision of the cyst under local anesthesia. The incision healed well with no postoperative complications. Considering that a dermoid cyst has the potential to become infected or progress into squamous cell carcinoma, its removal at an early stage is suggested. Few reports in the literature have described a dermoid cyst that secretes hemorrhagic contents from a congenital sinus tract. We present this case to provide a reference for clinicians.

Abstract Purpose To review our experience with pediatric congenital buttock sinus tract, and to conclude the clinical characteristics and management of the disease. Methods Twenty-two pediatric patients diagnosed with congenital buttock sinus tract were included. Medical records were reviewed, and the patients were followed up. Continuous variables were presented by median and range. Categorical variables were presented as frequencies and percentages. Results Among the 22 patients, there were 8 boys (36.4%) and 14 girls (63.6%). The median first onset age was 42 months, and the range was 5 months to 12 years old. Admission age was 69.5 months, with a range from 14 months to 12 years old. Overall prior treatment time was 11 months, ranging from 3 months to 11 years. Twenty-one patients had definite congenital dimples since birth, and later manifested with infection through the dimple. All patients came to the doctor with complaint of the infection. The number of invasive procedures ranged from 0 to 5, with an average of 2. Radiology could exactly display the morphology and show the termination as a retrorectal cyst. The surgical procedure was adopted trans-fistula tract, and the pathological results showed a dermoid cyst in 11 patients and an epidermoid cyst in 10 patients. During the follow-up period of 34.5 months (range, 2 months to 8 years), 19 patients were uneventful and 3 patients suffered recurrence. Two of them underwent a second operation and had no recurrence ever since. The third patient did not receive a second operation, and the refractory infection was still present. Conclusions Pediatric congenital buttock sinus tract is rare and has a female predominance in the morbidity. Patients have a distinctive congenital dimple on the buttock with recurrent infection, and there usually exists a congenital sinus tract from the dimple to the retrorectal space. Total excision is the only method for the cure. The nature of the disease is a retrorectal developing dermoid cyst or epidermoid cyst.

Ectopic Cilia

Ectopic cilia are extremely rare congenital anomalies in which eyelash follicles appear in an abnormal place on the eyelid, most typically on the lateral quadrant of the anterior surface of the upper eyelid. In the majority of cases, simple surgical excision of ectopic cilia is indicated because of its cosmetic aspect. There is usually no associated medical co-morbidity with this anomaly. The authors report an unusual case of ectopic cilia associated with an orbital dermoid cyst and sinus tract. A 3-year-old boy was initially diagnosed with ectopic cilia on the left upper eyelid. There was no history of inflammation or swelling of the eyelid. An ophthalmological examination revealed only 1 mm of ptosis; no proptosis, inferior displacement, or palpable orbital mass was present. During surgical excision of the ectopic cilia, a thin sinus tract was identified, leading posteriorly to the orbit. Magnetic resonance imaging performed after the excision showed a supraorbital extraconal mass just below the roof of the left orbit. A supraorbital 2-piece craniotomy was performed with total extirpation of the dermoid cyst. The cyst was removed en bloc without damage to the extraocular muscles, but the sinus tract could no longer be identified. Follow-up MRI was performed 6 months after surgery and showed no evidence of recurrence. A follow-up ophthalmological examination showed no signs of inferior displacement or proptosis. To the best of the authors’ knowledge, this case is the first reported instance of ectopic cilia associated with a dermoid cyst and sinus tract in which no typical clinical signs and symptoms of possible orbital pathology were present. This case highlights the value of radiological examination in all cases of ectopic cilia prior to surgical excision.

Dermal Sinus Tract

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.
