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.

Keratin granulomas in the peritoneum are a rare finding with multiple etiologies and can be especially challenging for both the pathologist and the surgeon when these lesions are grossly visible. We report a case of a unique frozen section diagnostic scenario of evaluation of keratin granulomas in the peritoneum of a 47-year-old woman in the setting of multiple potential culprits: endometrial endometrioid adenocarcinoma following fertility sparing treatment, and a concurrent dermoid cyst. We discuss the various etiologies of keratin granulomas in the peritoneum, mechanism of their formation, diagnostic significance, as well as implications of fertility sparing treatments. To the best of our knowledge, this is the only case of keratin granulomas in the peritoneum with multiple distinct potential pathologic culprits as well the only case following fertility sparing treatment.

Coronal Incision

OBJECTIVEUp to 10% of midline nasal dermoid cysts have intracranial extension. Previous techniques of excision include frontal and frontonasal craniotomies via a coronal approach, combined with a direct cutaneous excision of the dermoid cyst. While the coronal incision allows for wide visualization, it carries significant risks of transfusion, blood loss, and scarring. The authors present an alternative technique in which access is gained through a midline extension of the dermoid cyst excision that provides direct access for a keyhole frontal craniotomy.METHODSThe authors utilize a nasal bone osteotomy, pericranial flap, and keyhole-type craniotomy performed through a nasal midline incision for the treatment of nasal dermoid cysts with intracranial extension. They performed a retrospective chart review of all patients with nasal dermoid cysts treated at the Ann & Robert H. Lurie Children’s Hospital of Chicago from 2009 to 2017. Patient demographic data, operative data, and in- and outpatient complication data were collected.RESULTSIn 10 patients with cyst extension near or into the intracranial cavity (7 with true intracranial extension), the nasal osteotomy technique was performed. The mean blood loss was 13 ml, with a 0% transfusion rate. The mean length of inpatient stay was 1 day. A durotomy was made and repaired as part of the dermoid cyst dissection in 3 patients. One patient underwent intraoperative placement of a lumbar drain. The mean operative time was 228 minutes. There were no intraoperative or postoperative complications, including the need for a reoperation. No patients had any long-term complications, and no patients have had dermoid cyst recurrence. The appearance of the scar was acceptable in all cases.CONCLUSIONSThe midline approach to nasal dermoid cysts with intracranial extension is safe and results in limited blood loss, short operative times, and short lengths of inpatient hospital stay. This is a viable technique for the treatment of this challenging pathology.

<p class="abstract">We describe a case of a craniofacial dermoid cyst in a 16-month boy treated at our tertiary referral centre. The patient presented with a soft tissue swelling in the mid forehead extending down to the glabella. Computed tomography and magnetic resonance imaging scans demonstrated a peripherally enhancing cystic lesion with a defect in the underlying frontal bone. The clinical and imaging features were suggestive of a dermoid cyst with intracranial extension. The cyst became infected pre-operatively and this episode was managed by aspiration and antibiotics. Definitive management was by excision of the extra and intra-cranial components of the lesion via a bifrontal craniotomy. The presentation, investigations and management of this lesion is discussed.</p>

Introduction: Dermoid cysts in the anterior fontanel are rare lesions, problems around 0.1–0.5% of all cranial tumors. It originated during the early stages of development and derived from embryonic epithelial tissue located along the midline. CT and NMR studies are of choice to rule out intracranial extension. They are diagnosed and treated with surgery in childhood. In this article, a review of the literature on this pathology is performed and a clinical case is reported in order to show the results of imaging studies in the Dermoid Cyst in childhood. Case Presentation: Four-month-old female infant with Dermoid Cyst in the Anterior Fontanelle, without neurological compromise who was once a surgery. The surgical piece affected uniform, encapsulated, mobile, soft lesion with clear content. The obstetric history, clinical data, physical examination, imaging and histopathological studies confirmed the diagnosis of Dermoid Cyst, the patient’s postoperative evolution is satisfactory, currently undergoing follow-up by Neuropediatrics. Conclusion: in simple pediatric patients with Dermoid Cyst in the anterior Fontanelle, simple Computerized Axial Skull Tomography is very useful for its diagnosis, as well as the performance of surgical treatment and postoperative follow- up for a favorable evolution and better prognosis. Keywords: dermoid cyst, anterior fontanelle, congenital inclusion cyst, case report. RESUMEN Introducción: La frecuencia de presentación del Quiste Dermoide en fontanela anterior es muy baja y se desarrollan en la etapa embrionaria de la vida en la que el tejido embrionario de la línea media dá lugar a su formación. Los estudios de TAC y RMN son de elección para descartar la extensión intracraneal. Se diagnostican y tratan con cirugía en la niñez. En este artículo se realiza una revisión de la literatura sobre esta patología y se relata un caso clínico con el objetivo de mostrar los resultados de estudios imagenológicos en el Quiste Dermoide en la infancia. Presentación de Caso: Lactante femenina de cuatro meses con Quiste Dermoide de la fontanela anterior sin complicaciones fue intervenida quirúrgicamente. Se realizó excéresis de lesión blanda, encapsulada y movible. Los antecedentes obstétricos, datos clínicos, examen físico, estudios imagenológicos e histopatológico confirmaron el diagnóstico de Quiste tipo Dermoide, la evolución posoperatoria de la paciente es satisfactoria, actualmente en seguimiento por Neuropediatría. Conclusiones: En pacientes pediátricos con Quiste Dermoide en la Fontanela anterior es de gran utilidad la Tomografía Axial Computarizada simple de Cráneo para su diagnóstico, así como, la realización de un tratamiento quirúrgico y el seguimiento postoperatorio para una favorable evolución y mejor pronóstico.

ABSTRACT Nasal dermoid is a rare developmental anomaly. Unlike other craniofacial dermoid, the nasal lesions can present as a cyst, a sinus or fistula and may have an intracranial extension. We report a case of 11-year-old male child presenting in the ENT OPD of Pravara Rural Hospital with a tuft of hair over the root of the nose since birth, which is uncommon presentation of nasal dermoid.

✓ An unusual type of dermoid cyst is reported in 10 African infants. In these cases a soft, cystic mass located over the anterior fontanel was noted shortly after birth and gradually enlarged. The cyst had no intracranial extension and was easily excised intact. The clinical and x-ray findings of the cyst are described and compared with the usual dermoids. The histology and the contents of the cyst are detailed and some peculiarities of this lesion pointed out.
