RESUMO
Dermoid cysts (DCs) and epidermoid cysts (ECs) are uncommon developmental cysts affecting the oral cavity. This study aims to evaluate patients with oral DCs and ECs and their demographic and clinicopathologic features. A retrospective descriptive cross-sectional study was performed. A total of 105,077 biopsy records of oral and maxillofacial lesions from seven Brazilian oral pathology centers were analyzed. All cases diagnosed as oral DCs and ECs were reviewed, and clinical, demographic, and histopathological data were collected. The series comprised 32 DCs (31.4%) and 70 ECs (68.6%). Most of the DCs occurred on the floor of the mouth (n = 14; 45.2%) of women (n = 17; 53.1%) with a mean age of 34.6 ± 21.6 years. All DCs were lined partially or entirely by stratified squamous epithelium (100%). Chronic inflammatory cells, melanin pigmentation, multinucleated giant cell reaction, and cholesterol clefts were observed in the fibrous capsule . Most of the ECs affected the labial mucosa (n = 20; 31.7%) of men (n = 39; 56.5%) with a mean age of 48.0±19.8 years. Microscopically, most ECs (n = 68; 97.1%) were lined entirely by stratified squamous epithelium. Two cysts (2.9%) showed areas of respiratory metaplasia. Chronic inflammatory cells, melanin pigmentation, multinucleated giant cell reaction, and cholesterol clefts were also observed in the fibrous capsule. Conservative surgical excision was the treatment of choice in all cases. Oral DCs and ECs are uncommon and often clinically misdiagnosed lesions. Clinicians should consider DCs and ECs in the differential diagnosis of soft tissue lesions in the oral cavity, mainly located on the floor of the mouth and labial mucosa.

BACKGROUND Dermoid cysts are rare benign intracranial tumors that usually present classic computed tomography (CT) and magnetic resonance imaging (MRI) characteristics, allowing for relatively simple diagnostic confirmation. Atypical imaging features can occur due to their diverse ectodermal-derived content, which can result in a diagnostic dilemma. Making an accurate diagnosis is essential for adequate management. CASE REPORT We present a case of a 39-year-old woman with past medical history of increased blood pressure, presenting with worsening headaches non-refractory to medication. Imaging revealed an extra-axial lesion within the midline posterior fossa with an occipital transdiploic linear channel. The lesion was T2 profoundly hypointense on brain MRI, and prominently hyperdense on non-contrast CT scan. Catheter angiography excluded vascular etiology. After complete lesion resection, results of the histopathologic examination were consistent with a dermoid cyst. Dermoid cysts that are hyperdense on CT and hypointense on T2-WI are extremely rare. CONCLUSIONS Complete surgical resection is the treatment of choice for most dermoid cysts. Atypical radiologic features, in an already rare intracranial tumor, can delay correct diagnosis and management. Recognition of these findings is therefore important for adequate imaging analysis of these lesions.

Introduction The pineal gland is a common location for intracranial germ cells, but dermoids are not commonly observed in this area. In the present paper, we discuss the clinical and radiological features as well as the treatment and outcome of this cyst in a 6-year- old child with a pineal dermoid cyst. Case Presentation The patient presented with chronic headache 6 months before admission in 2018. On the first admission, an enhanced lesion with a small cyst was detected in brain imaging. Magnetic resonance imaging (MRI) of the brain at follow-up (2 months after the first presentation) showed enlargement of the cyst size with compression on the adjacent structures. Radical excision of the tumor was performed after the endoscopic biopsy due to pressure exerted on the adjacent structures. Conclusion Dermoid cyst should be considered as a differential diagnosis for enhanced lesions of the pineal region.

Este artículo tuvo como objetivo describir las características clínicas, imagenológicas y la evolución posquirúrgica del quiste dermoide intraorbitario. Los quistes dermoides representan entre 3-9 por ciento de todos los tumores intraorbitarios. Se forman por el secuestro del ectodermo entre las líneas de fusión embrionaria de derivados mesodérmicos. La mayoría de los quistes dermoides son superficiales, y se presentan en la infancia temprana como aumentos de volumen discretos en ceja y párpado. Su crecimiento es lento, y generalmente se asocian a las suturas frontocigomática y frontoetmoidal. Es infrecuente su localización intraorbital. Se presenta una paciente femenina de 5 años de edad, quien fue ingresada con proptosis progresiva. Los exámenes imagenológicos mostraron un quiste intraorbitario derecho a nivel del proceso cigomático del frontal con erosión ósea subyacente. Se realizó su resección quirúrgica mediante orbitomía lateral por la técnica de Krönlein. El examen histopatológico informó quiste dermoide. Su evolución fue satisfactoria(AU)
This article aimed to describe the clinical and imaging characteristics of the intraorbital dermoid cyst, and its postoperative evolution. Dermoid cysts represent 3 percent-9 percent of all intraorbital tumors. They result from sequestrum of the ectoderm between the embryonic fusion lines of mesodermal derivatives. Most dermoid cysts are superficial, presenting in early childhood as a discrete volume increase in the eyebrow and the eyelid. Their growth is slow and they are generally associated to the frontozygomatic and the frontoethmoidal sutures. An intraorbital location is infrequent. A case is presented of a female 5-year-old patient admitted for progressive proptosis. Imaging studies showed a right intraorbital cyst at the level of the frontozygomatic process with underlying bone erosion. Surgical resection was performed by lateral orbitotomy with Krönlein's technique. Histopathological examination revealed a dermoid cyst. The patient's evolution has been satisfactory(AU)

Intraconal dermoid cysts are very unusual in routine clinical practice. Clinical symptoms depend upon the site and extension of the lesion. Though rare, proptosis, diplopia, and orbital pain are the presenting symptoms encountered in patients with an intraorbital dermoid cyst. Although radiology can be diagnostic, a complete correlation with the final histopathology is always mandatory for its confirmation. Endoscopic excision of the cyst ensures a complete cure for the disease without any intraoperative/postoperative complications.

Las lesiones de la región nasofrontal en los niños son un reto diagnóstico debido a su rareza, y su potencial comunicación con el sistema nervioso central también aumenta su complicaciones. Dentro de las principales entidades de esta región se encuentran los quistes dermoides, los gliomas nasales y los encefaloceles. Un abordaje diagnóstico y terapéutico inapropiado podría generar desde simples recurrencias hasta fistulas e infecciones en el sistema nervioso central, que podrían contribuir a mayores complicaciones o incluso, poner en riesgo la vida de los pacientes.
Injuries to the naso-frontal region in children are a diagnostic challenge, associated with their rarity, their complexity also implies their potential communication with the central nervous system. Dermoid cysts, nasal gliomas, and encephaloceles are among the main entities in this region. An inappropriate diagnostic and therapeutic approach could generate from simple recurrences (as in our case), to fistulas and infections of the central nervous system that could contribute to greater complications or even put the lives of patients at risk.

Intracranial dermoid cysts are benign congenital slow growing masses. They account for less than 1% of all primary intracranial lesions. They can be asymptomatic and appear incidentally on brain images. However, there are some dermoid cysts that, depending on the location, can cause a variety of symptoms, especially if they compress vital structures. Rupture of intracranial dermoid cysts is relatively uncommon; the incidence is 0.18%. Dermoid cyst in children appears in the posterior fossa, while in adults is more common to find them in the sellar, temporal, and frontobasal region. The Meckel's cave is not a frequent location for these lesions and there are only a few cases in the adult population reported in the literature. We presented a 12-year-old patient with a dermoid cyst in the Meckel's cave who first presented with symptoms of a ruptured cyst but eventually evolved with a trigeminal neuralgia. We decided to do a transzygomatic approach and a middle fossa pealing to locate and excise the lesion. After surgery, the patient resolved the symptoms. Surgery is recommended in symptomatic lesions although surgical decision-making should consider the region where the cyst is located to achieve a safe, maximal resection without adding any further damage.

BACKGROUND Encephalocraniocutaneous lipomatosis is a rare neurocutaneous disorder characterized by cutaneous, ocular, and central nervous system anomalies; its molecular etiology was recently identified. This report describes the surgical treatment and genetic characterization of a giant ocular lipodermoid cyst secondary to encephalocraniocutaneous lipomatosis. CASE REPORT An 11-year-old girl with past medical history of absence seizures presented with a reddish protruding mass in her right eye involving the temporal conjunctiva and the peripheral temporal cornea; eyelid closure was not possible due to mass protrusion. She also presented skin tags at the level of the external canthus and 3 alopecic areas at the level of the scalp compatible with nevus psiloliparus. No family history was reported. A dermoid cyst was suspected and excisional biopsy was performed under general anesthesia. A large conjunctival and lamellar corneoscleral resection was done, followed by a corneal tectonic graft. Molecular analysis was carried out, including PCR and Sanger sequencing on DNA obtained from the mass. After surgery, the patient achieved complete eyelid closure, reduction of ocular surface symptoms, and improved aesthetic appearance. Histological analysis confirmed a lipodermoid cyst; genetic tests confirmed a mosaic activating mutation in FGFR1 (c.1638C>A, p.Asn546Lys). The diagnosis was encephalocraniocutaneous lipomatosis. CONCLUSIONS ECCL is a rare condition; an accurate diagnosis comprising clinical and genetic aspects can facilitate the monitoring of possible complications, improve the multidisciplinary treatment, and provide valuable information for future therapy developments. In this case, the patient's quality of life improved significantly, ocular symptoms disappeared, and a good esthetic appearance was achieved.

Introduction Intracranial dermoid tumors represent a rare clinical entity that accounts for 0.04 to 0.6% of all intracranial tumors. Their location in the posterior fossa is uncommon. Objectives To report the case of a young woman with a posterior fossa dermoid cyst treated by right far lateral approach. Case Report A 17-year-old woman presenting with swallowing difficulties for 6 weeks was referred for a neurological investigation. Amagnetic resonance imaging (MRI) scan showed a hyperintense T1-weighted large expansive lesion occupying the posterior fossa and compressing the anterior face of the brain stem and cerebellum. The patient underwent surgical treatment by right far lateral approach with decompression of vascular and neural structures. The patient presented an uneventful recovery, and was discharged home on the fourth postoperative day without any additional neurological deficits. The anatomopathological analysis confirmed the diagnosis of dermoid cyst. Conclusion The far lateral approach is a safe and feasible route to appropriately treat large posterior fossa dermoid cysts. Decompression of vascular and neural structures is essential to achieve good symptom control.

BACKGROUND: The dermoid cyst considered a cystic teratoma derived from embryonic germinal epithelium is a slow-growing benign tumour. Dermoid cysts may occur in the orbital and periorbital region in paediatric patients and are often recurrent. The surgical approach depends upon the site of the lesion, superficial or deep. To our knowledge, this is the first described case of a patient with resection of dermoid cyst treated with human amniotic membrane implant and topical application of 0.02% mitomycin C. CASE PRESENTATION: We present a case of a 12-year-old male with a tumour in the superotemporal region of the right eye (RE). Symptoms included decreased visual acuity (VA), burning eye, foreign body sensation, and photophobia of the affected eye. A physical examination detected blepharospasm. Ophthalmic examination of his RE, fingers count from a 1-2 m distance, showed no improvement with pinhole. Visual acuity was 20/20 on the left eye (LE). The bio-microscopic examination confirmed the presence of a tumour mass (15 mm × 12 mm) on the surface of the RE, invading the superotemporal sector. The tumour had a lobulated appearance, a shiny and vascularized surface covered by conjunctiva, a pearlescent-pink colour, a medium consistency, was renitent and painless. An ultrasound scan revealed atrophy of the pigmented retinal epithelium with scleral indentation of the RE. A computed tomography (CT) scan revealed a recurrent lesion consistent with an epibulbar dermoid cyst. Surgical excision of the lesion was performed and a human amniotic membrane (HAM) graft and topical 0.02% mitomycin C (MMC) were applied. Histopathological analysis confirmed the diagnosis of recurrent dermoid cyst. CONCLUSION: In this case report, we describe a case of recurrent epibulbar dermoid cyst treated with complete resection; topical MMC and HAM implant with good clinical outcome of the lesion and implant adhesion. Resection of a cyst of the ocular surface is not recommended when a large epibulbar dermoid tissue needs to be resected and no HAM graft is available.

Afecções oftálmicas têm se tornado cada vez mais frequentes na clínica de grandes animais, os defeitos epiteliais são frequentes e apresentam certo risco na clínica oftalmológica diária. O dermóide, presença de tecido cutâneo, constituído ou não de derme, epiderme, folículos pilosos e pelos ectópico, origina-se durante o período embrionário do animal e em ruminantes. Como tratamento de eleição foi utilizada a exérese cirúrgica, entretanto foi necessário um tratamento pós-cirúrgico com terapias à base de antibióticos e anti-inflamatórios. Utilizado como forma de substituição de colírios à base de antibióticos e anti-inflamatórios, o soro autólogo (SA) tem ganhado cada vez mais espaço no que diz respeito à tratamentos alternativos. Foi encaminhado para o Hospital Veterinário da Universidade Federal Rural do Semiárido (HOVET/UFERSA), uma bezerra com aproximadamente 10 meses de idade, apresentando uma protrusão de tecido ectópico na região periocular. O procedimento para exérese do dermóide foi realizado no centro cirúrgico do HOVET e como tratamento pós-cirúrgico, a fim de se elucidar a atividade do soro autólogo no controle bacteriano, foi preconizado o uso de 1 gota do soro autólogo, quatro vezes ao dia, durante 30 dias. O tratamento com soro autólogo na concentração de 100% se mostrou como um eficiente agente bactericida no tratamento pós-cirúrgico.
Ophthalmic disorders have become increasingly frequent in the clinical practice of large animals, epithelial defects are frequent and they also present some risk in the daily ophthalmologic clinic. The dermoid, the presence of cutaneous tissue, consisting of the dermis, epidermis, hair follicles and ectopic hairs, originates during the embryonic period of the animal and in ruminants. Its etiological mechanism involved in the pathogenesis is not yet sufficiently elucidated. As treatment, surgical excision is used, however, post surgical treatment with antibiotic and anti-inflammatory therapies are necessary. Used as a substitute for antibiotic and anti-inflammatory drops, autologous serum (SA) has gained more and more space in substitution to alternative treatments. A 10 months of age calf, resenting a protuberance of ectopic tissue in the periocular region, was addimited in the Veterinary Hospital of the Federal Rural Semi-Arid Federal University (HOVET /UFERSA). The procedure for the removal of the dermoid was performed at the surgical center of HOVET and as a post surgical treatment to elucidate the autologous serum activity in the bacterial control, the use of 1 drop of autologous serum was recommended four times a day during 30 days. Treatment with 100% autologous serum was shown to be an efficient bactericidal agent in post-surgical treatment.
