Tratamento cirúrgico do cisto epidermóide situado anteriormente ao osso hióide: relato de caso / The surgery treatament of epidermoid cyst situated anteriorly to the hyoid bone: case report / Tratamiento quirúrgico del quiste epidermoide situado anterior al hueso hioides: reporte de um caso

O cisto epidermóide (CE) é uma má formação cística de desenvolvimento incomum. Ocorre mais comumente na linha média do assoalho da boca, ocasionalmente localiza-se lateralmente ou em outros sítios. A etiologia do CE ainda é incerta, mas acredita-se que esteja associado a remanentes do ectoderma durante a fusão do primeiro e segundo arcos branquiais. A lesão cresce lentamente sem provocar dor, apresentando-se como massa de consistência semelhante à de borracha ou à massa de pão. Seu diagnóstico se dá por meio de exame clínico e exames complementares de imagem como tomografia computadorizada, ressonância magnética e/ou ultrassonografia, entretanto somente com o exame histopatológico é possível um diagnóstico definitivo. A excisão cirúrgica do cisto é o tratamento de escolha. Quando o diagnóstico é precoce e a intervenção correta, o índice de recidiva torna-se raro. Diante da raridade de casos na região maxilo facial e a dificuldade relacionada ao diagnóstico, o presente trabalho tem como objetivos descrever a ocorrência do cisto epidermóide bem como seu diagnóstico através de exame histopatológico/exames de imagem, tratamento cirúrgico e contribuir com a literatura já existente por meio de um relato de caso que foi diagnosticado no Serviço de Patologia Bucal da Universidade de Gurupi, campus Gurupi/TO.

Epidermoid cysts (EC) is an unusually developing cystic malformation that occurs most frequently in the midline of the floor of the mouth, occasionally located laterally or elsewhere. The etiology of the (EC) still uncertain, but it is believed to be associated with remnants of the ectoderm during the fusion of the first and second branchial arches. The lesion grows slowly without causing pain, presenting itself as a mass with a consistency like of rubber or bread dough. Diagnosis of (EC) is made through complementary imaging tests such as computed tomography, magnetic resonance imaging and/or ultrasound, only histopathological examination it is possible to obtain a definitive diagnosis. Surgical excision of cyst is the treatment of choice. When the diagnosis is made early and the intervention is correct, the recurrence rate is rare. Given the rarity of cases in the maxillofacial region and the difficulty related to diagnosis, this study aims to describe epidermoid cysts occurrence and your diagnostic through of histopathologic/imagine exams, surgical treatment and contribute to the existing literature, through a review and description of a clinical case that was diagnosed at the Oral Pathology Outpatient Clinic at the Faculty of Dentistry - University of Gurupi - UNIRG. Gurupi -Tocantins. Brazil.

El quiste epidermoide (CE) es una malformación quística de desarrollo infrecuente. Ocurre más comúnmente en la línea media del piso de la boca, ocasionalmente se localiza lateralmente o en otra parte. La etiología de la FB aún es incierta, pero se cree que está asociada con restos del ectodermo durante la fusión del primer y segundo arcos branquiales. La lesión crece lentamente sin causar dolor, apareciendo como una masa con una consistencia similar a la de la goma o la masa de pan. Su diagnóstico se realiza a través del examen clínico y pruebas de imagen complementarias como tomografía computarizada, resonancia magnética y/o ultrasonografía, sin embargo, solo con el examen histopatológico es posible un diagnóstico defi nitivo. La escisión quirúrgica del quiste es el tratamiento de elección. Cuando el diagnóstico es temprano y la intervención es correcta, la tasa de recurrencia se vuelve rara.

Choroid plexus papilloma in a mature cystic teratoma of ovary: A rare case report

Mature cystic teratoma of the ovary is the most common type of germ cell tumor. It constitutes approximately 20% of all ovarian neoplasms. As a rare occurrence, however, several types of benign and malignant tumours developing secondarily in dermoid cysts have been reported. Those of central nervous origin are almost exclusively gliomas of astrocytic, ependymal or oligodendroglial lineage. Choroid plexus tumors are unusual intracranial tumors which comprised of only 0.4?0.6% of all brain tumors. These are neuroectodermal in origin and similar in structure to a normal choroid plexus in the form of multiple papillary fronds mounted on a well vascularized connective tissue stroma. The present case report highlights the presence of a choroid plexus tumor in a mature cystic teratoma of the ovary in a 27?year?old woman who came for safe confinement and cesarean section.

A rare case of intracranial dermoid cyst in a young woman � A case report

Intracranial dermoid cysts generally occurring along the midline are rare. They are benign, congenital, slow-growing cystic lesions located inside the skull. They account for<1% of all primary intracranial tumors and are more common in females in the first three decades of life. Many intracranial dermoid cysts are asymptomatic and are found by chance when brain imaging is carried out for other reasons. Clinical presentation usually relates to compression of adjacent structures or spontaneous rupture of the cyst. The signs and symptoms may range from headaches, seizures to cerebral ischemia. On CT imaging these lesions usually appear as well-defined lobulated midline masses with low attenuation and hyperintense on T1-weighted MRI imaging. We hereby report a case of an 18-year-old female presented with history of seizures involving right upper limb which spread to other limbs associated with frothing and tongue bite- 3 episodes since 2 months. She also had cleft lip. On examination CT images showed hypodense lesion in intrahemispheric region in frontal lobe and MRI image with contrast showed hyperintense T2W, hypointense T1W/FLAIR lesion. A diagnosis of an intracranial dermoid cyst in the intrahemispheric region of frontal lobe was made and the patient was advised a surgical excision of the cyst.

Clinicopathologic analysis of oral dermoid and epidermoid cysts: a Brazilian multicenter study

Abstract 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.

Correlación clínico-cito histológica de los quistes congénitos cervicales

Los quistes constituyen una cavidad patológica revestida por una pared de tejido conectivo definida y con un tapiz epitelial. Se tuvo como objetivo determinar la correlación de los diagnósticos clínico y citológico en los quistes congénitos Cervicofaciales. Se realizó un estudio retrospectivo de los pacientes con diagnóstico clínico, citológico y/o histológico de quiste tirogloso, branquial y demodé, atendidos en el hospital Universitario Carlos Manuel de Céspedes de Bayamo, durante cinco años. Se calculó la sensibilidad, especificidad y seguridad del diagnóstico clínico y la biopsia por aspiración con aguja fina (FNAC) para cada quiste. El diagnóstico clínico fue de 93,3%, 60,0% y el 100,0 % para los quistes tirogloso branquial y dermoide respectivamente. Encontramos mayor tendencia al error clínico en los quistes branquiales, donde las confusiones más frecuentes se presentan con linfoadenopatías inflamatorias. El diagnóstico por aspiración con aguja fina fue de 93.3% y el 60% para los quistes tirogloso y branquial respectivamente. Se concluyó que el diagnóstico clínico no es suficiente en ocasiones, por lo que es preciso recurrir a medios diagnósticos complementarios, como la biopsia por aspiración con aguja fina; sin embargo esta prueba no es 100% segura.

Cysts constitute a pathological cavity lined by a defined connective tissue wall and with an epithelial tapestry. The objective was to determine the correlation of clinical and cytological diagnoses in congenital cervicofacial cysts. A retrospective study of patients with clinical, cytological and/or histological diagnosis of thyroglossal, branchial and demodé cysts, attended at the Carlos Manuel de Céspedes University Hospital in Bayamo, for five years, was conducted. We calculated the sensitivity, specificity and safety of clinical diagnosis and fine needle aspiration biopsy (FNAC) for each cyst. The clinical diagnosis was 93.3%, 60.0% and 100.0% for branchial thyroglossal and dermoid cysts respectively. We found a greater tendency to clinical error in branchial cysts, where the most frequent confusions occur with inflammatory lymphadenopathy. The diagnosis by fine needle aspiration was 93.3% and 60% for thyroglossal and branchial cysts respectively. It was concluded that clinical diagnosis is sometimes not sufficient, so it is necessary to resort to complementary diagnostic means, such as fine needle aspiration biopsy; However, this test is not 100% safe.

O objetivo foi determinar a correlação dos diagnósticos clínicos e citológicos em cistos cervicofaciais. Foi realizado um estudo retrospectivo de pacientes com diagnóstico clínico, citológico e/ou histológico de cistos tireoglossos, branquiais e demodé, atendidos no Hospital Universitário Carlos Manuel de Céspedes, em Bayamo, por cinco anos. Foram calculadas a sensibilidade, especificidade e segurança do diagnóstico clínico e da punção aspirativa por agulha fina (PAAF) para cada cisto. O diagnóstico clínico foi de 93,3%, 60,0% e 100,0% para cistos branquiais tireoglosso e dermóide, respectivamente. Encontramos maior tendência ao erro clínico nos cistos branquiais, onde as confusões mais frequentes ocorrem com linfadenopatia inflamatória. O diagnóstico por punção aspirativa por agulha fina foi de 93,3% e 60% para cistos tireoglossos e branquiais, respectivamente. Concluiu-se que o diagnóstico clínico às vezes não é suficiente, sendo necessário recorrer a meios diagnósticos complementares, como a punção aspirativa por agulha fina; No entanto, este teste não é 100% seguro.

This case highlights the importance of histopathological examination in all cases of choristoma undergoing excision.

A RARE CAUSE OF LOWER LIMB PAIN - INTRAMEDULLARY DERMOID - A CASE REPORT

Dermoid cyst is a benign tumor. It accounts for only 1-2% of intra spinal tumors. -It is most common in children less than 10yrs of age accounting for 10-17%. -Only 1% of dermoid cyst occurs intramedullary. The usual sites are lumbosacral spine(60%), thoracic spine(10%), and cervical spine(10%). -The common presentation is with pain in lower limbs, back pain, balance problems, numbness and weakness, seizures, headaches. Here we are presenting 4 year male child.

An Unusual Dermoid Cyst of the Pineal Region: Case Report in a Child

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.

Quiste dermoide intraorbitario / Intraorbital dermoid cyst

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)

Quiste dermoide nasofrontal: presentación de un caso y revisión narrativa / Nasofrontal dermoid cyst: case presentation

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.

Quiste dermoide en base de cráneo con trayecto fistuloso a punta nasal en un paciente pediátrico: reporte de caso / Skull base dermoid cyst fistulizing to the nasal tip in a pediatric patient: case report

El quiste dermoide es una lesión congénita poco frecuente, secundario a una regresión incompleta de tejido ectodérmico, y su incidencia es de 1/20 000-40 000 nacidos vivos. Debe realizarse una resección quirúrgica oportuna para prevenir el compromiso intracraneal y/o las complicaciones. El estudio imagenológico determina su extensión. Se han recomendado diferentes enfoques quirúrgicos, los cuales deben cumplir con los cuatro principios de Pollock. El siguiente estudio presenta el caso de un paciente pediátrico, de nueve meses de edad, con un quiste dermoide en la base del cráneo asociado con un trayecto fistuloso a punta nasal. La resonancia magnética nuclear (RMN) contrastada evidenció una masa quística en la región anterior a la crista galli comunicada con el tracto fistuloso a la punta nasal. El paciente fue llevado a cirugía para realizar la resección del quiste mediante rinoplastia externa combinada con abordaje endoscópico transnasal. Los resultados funcionales y estéticos fueron satisfactorios, sin recurrencia. Se evidenció una fístula de líquido cefalorraquídeo intraoperatoria corregida en el mismo tiempo quirúrgico.

The dermoid cyst is a rare congenital lesion, secondary to an incomplete regression of ectodermal tissue. Its incidence is 1/20,000-40,000 live births. Timely surgical resection must be performed to prevent intracranial involvement and/or complications. Imaging study determines its extension. Different surgical approaches have been recommended; all must adhere to Pollock's 4 principles. The following study presents the case of a pediatric patient, 9 months old, with a dermoid cyst at the skull base with a fistulous path to the nasal tip. Contrasted nuclear magnetic resonance revealed a cystic mass in the region anterior to the crista galli communicated with a fistulous tract at the nasal tip. The patient was taken to surgery for cyst resection by external rhinoplasty combined with a transnasal endoscopic approach with satisfactory functional and aesthetic results, without recurrence. A Cerebrospinal fluid fistula was evidenced, as an intraoperative complication, it was corrected in the same surgical time.

Intraconal orbital dermoid cyst: a rare location

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.

Quiste dermoide latero cervical / Dermoid cyst of the lateral neck

Resumen Introducción: Los quistes dermoides son lesiones de origen ectodérmico poco frecuentes. Solo un 1,6% de ellos, se presenta en el piso de la boca y de éstos, solo un 6% lateralmente en el espacio submandibular. Objetivo: Reporte de caso y revisión de la literatura. Caso clínico: Se presenta un caso de una paciente de 32 años, con un cuadro de 1 año de evolución caracterizado por una lesión de crecimiento lento pero sostenido. Se le realizó la resección de la lesión junto con una submandibulectomía ipsilateral resultando compatible con un quiste dermoide. Discusión: La localización de esta lesión es muy infrecuente. En el estudio histopatológico son lesiones con epitelio pluriestratificado cornificado y anexos cutáneos. El estudio de imágenes orienta a una lesión quística, siendo la resonancia nuclear hoy en día el mejor examen para caracterizar esta lesión. Es una lesión benigna, sin recidivas reportadas cuando la resección ha sido completa.

Introduction: Dermoid cysts are uncommon lesions from ectodermic origin. Only 1.6% arise in the floor of the mouth, and at this site only 6% arise laterally in the submandibular region. Aim: Case report and review of the literature. Clinical Case: 32 years old patient, with a slow growing lesion during 1 year. Complete resection with an ipisilateral submandibulectomy was performed. The pathologic report showed a dermoid cyst. Discussion: The localization of this lesion is very uncommon. In the pathologic report are lesion with pluri stratified cornified epthitelium with skin attachments. Image studies show a cystic lesion being the magnetic resonance the best study to characterize this lesions. Are benign lesions, without recurrence reported when the lesion has been fully excised.

Ovarian mass in pregnancy: case series

Ovarian masses in pregnancy are not uncommon. Ovarian masses during pregnancy should be accurately evaluated to identify the patients who need surgical interventions from those where it can be managed conservatively. Ultrasound and magnetic resonance imaging (MRI) are safe diagnostic tools during pregnancy. The overall incidence of ovarian tumours in pregnancy is 2.4-5.7%. Most masses are functional and asymptomatic and up to 70% resolve spontaneously in the second trimester. Both open surgery and laparoscopy can be performed considering the tumour diameter, gestational age and associated complications. A multidisciplinary approach is necessary in case of high suspicion of malignancy. This study evaluates the clinical features, course in pregnancy, management and pregnancy outcome in patients with ovarian masses diagnosed during pregnancy. This was a retrospective analysis of medical records of 6 patients diagnosed with ovarian mass during pregnancy in the department of Obstetrics and Gynaecology at Kanachur Institute of Medical Sciences, Mangalore from June 2019 to June 2020.

Congenital malformations in ruminants and its surgical management: a retrospective study of Sokoto veterinary clinic, Nigeria

Background:Congenital defects, abnormalities of structures or functions present at birth, maybe as a result ofgenetic or environmental factors or both and in most cases; the exact etiology is not clear but can occur in all animals. These abnormalities are responsible for slowing down of genetic progress and economic loss for the breeders, due to the death of animals.Methods:Available record of cases presented to Aliyu JedoVeterinary Clinic,Sokoto from December 2015 to 2019 was used to investigate congenital malformation in ruminants based on species and sex. Surgery was carried out in all the cases with local anaesthesia (infiltration technique) using lignocaine. Surgical procedures carriedout were rectopexy (atresia ani), gingivectomy (gingival fibromatosis), superficial keratectomy and temporary tarssorhaphy (dermoid cyst), casting and physiotherapy (contracted tendons). Results:A total of 47 congenital malformations; atresia ani 22 (46.8%), gingival fibromatosis 18(38.3%), dermoid cyst 6(12.8%), and contracted tendon 1(2.1%) were reviewed in the study.The ovine species had the highest incidence of cases load recorded 23(48.93%) followed by bovine 17(36.17%) and then caprine species7(14.89%). The incidence of all malformations was higher in males (68.1%) than in females (31.9%). All cases were attempted surgically with success in all the procedures.Conclusions:It can be concluded that male ruminants have the highest prevalence of congenital malformation. Congenital malformations are more frequently seen in ovine and least seen in caprine. Atresia ani appeared to be the most commonly reported cases

A rare case of extragonadal immature teratoma mimicking as subserosal pedunculated myoma

Immature teratomas are usually derived from a malignant transformation of mature teratoma. The pure immature teratoma accounts for less than 1% of all ovarian cancers. It is the second most common germ cell malignancy and accounts for 10-20% of all ovarian malignancies seen in women younger than 20 years of age. Extragonadal origin are extremely rare and the most common extragonadal site of these teratomas is the omentum. We hereby describe a case report of a 29-year-old lady who presented with abdominal pain and her imaging with an ultrasound revealed a mass with features suggestive of a subserosal fibroid. She underwent a laproscopic myomectomy. A histopathologic diagnosis of Immature teratoma was made following her primary surgery. She subsequently underwent a staging laparotomy which was followed by chemotherapy. Immature teratomas predominantly occur in young patients, and preservation of fertility is an important factor in its management. Treatment should be initiated as soon as possible after surgery, preferably within 7-10 days, in those patients who require chemotherapy.

Teratoma extragonadal del omento mayor, una localización poco usual: reporte de caso y revisión de la literatura / Extragonadal teratoma of the greater omentum, an unusual location: case report and review of the literature

Introducción. Los teratomas son masas de células totipotenciales, frecuentes en los ovarios o testículos. Su localización extragonadal es rara, siendo el epiplón aún más infrecuente. Hasta la actualidad se conocen aproximadamente 34 casos similares en la literatura. Presentación del caso. Se presenta una paciente de 61 años, con dolor en hemiabdomen inferior asociado a sensación de masa, con marcadores tumorales negativos e imágenes diagnósticas que muestran una masa encapsulada y calcificación anular interna sugestiva de necrosis grasa antigua versus tumor desmoide. Por la presentación clínica y los hallazgos imagenológicos se decide llevar a laparotomía exploratoria donde se encuentra masa quística dependiente de epiplón, con material sebáceo en su interior entremezclado con pelo y fragmentos óseos, que se reseca en bloque sin complicaciones. El informe del estudio histopatológico finalmente concluyó la presencia de un teratoma quístico maduro con cambios degenerativos. Por evolución satisfactoria se da egreso hospitalario. Discusión. El teratoma quístico extragonadal del epiplón es exótico en la literatura mundial, con escasos reportes de casos. En este caso, la resección mediante laparotomía resultó exitosa y sin complicaciones. Por su baja incidencia, la laparotomía ha sido una opción válida y segura para el manejo, no obstante conocer el caso permite plantear un abordaje con técnicas mínimamente invasivas

Introduction. Teratomas are totipotential cell masses, commonly located in the ovaries or testes. Its extragonadal location is rare, in the omentum being even rarer. To date, approximately 34 similar cases are known in the literature.Case presentation. A 61-year-old female patient is presented, with pain in the lower abdomen associated with a sensation of mass, with negative tumor markers and diagnostic images that show an encapsulated mass and internal annular calcification suggestive of old fat necrosis versus desmoid tumor. Due to the clinical presentation and the imaging findings, it was decided to carry out exploratory laparotomy where a cystic mass dependent on the omentum was found, with sebaceous material intermixed with hair and bone fragments, which was resected in bloc without complications. The histopathological study report finally concluded the presence of a mature cystic teratoma with degenerative changes. Due to satisfactory evolution, he was dis-charged from hospital.Discusion. Extragonadal cystic teratoma of the omentum is exotic in the world literature, with few case reports. In this case, the laparotomy resection was successful and uncomplicated. Due to its low incidence, laparotomy has been a valid and safe option for management, although knowing the case allows us to propose an approach with minimally invasive techniques

Oral hairy polyp in a teenager: case report and literature review / Pólipo piloso oral em um adolescente: relato de caso e revisão de literatura

ABSTRACT Objective: To report an unusual case of oral hairy polyp (HP) and review the literature, providing epidemiological, clinical and histopathological information on this disease. Case description: A 12-year-old male patient was referred to a Stomatology department with a nodule in the posterior midline of the tongue. The patient did not know exactly when it arose or whether it had grown since then. Clinical exam revealed a bulky and mobile pedunculated mass lesion on the dorsum of the tongue, with a diameter of approximately 1 cm. The patient's mother reported no previous health problem. An excisional biopsy was performed, the surgical specimen was sent for anatomopathological analysis, and the findings were compatible with the diagnosis of HP. Comments: Hairy polyp is a rare lesion, especially in the oral region. The literature search revealed only 10 case reports of oral HP published between January 1999 and January 2019, and they revealed a predominance of the disease in female newborns. Two uncommon facts were presented in this case: the patient was male and diagnosis was made at 12 years old.

RESUMO Objetivo: Relatar um caso incomum de pólipo piloso (PP) oral e revisar a literatura para trazer informações epidemiológicas, clínicas e histopatológicas acerca da doença. Descrição do caso: Paciente do sexo masculino, 12 anos de idade, encaminhado ao Departamento de Estomatologia com nódulo na região posterior de linha média da língua. O paciente não soube relatar quando surgiu a lesão e se ela havia crescido desde então. O exame clínico revelou massa pedunculada, volumosa e móvel no dorso da língua, medindo aproximadamente 1,0 cm de diâmetro. A mãe do paciente relatou que ele nunca havia tido nenhum problema de saúde anterior. Foi realizada biópsia excisional e o material foi enviado para análise anatomopatológica, sendo os achados compatíveis com o diagnóstico de PP. Comentários: O pólipo piloso é uma lesão rara, especialmente na região oral. A pesquisa bibliográfica revelou apenas dez relatos de casos de PP oral, publicados entre janeiro de 1999 e janeiro de 2019, sendo observada predominância da doença em recém-nascidos do sexo feminino. Dois fatos incomuns ocorreram neste caso: tratava-se de um paciente do sexo masculino e o diagnóstico se deu aos 12 anos de idade.

Autoamputation of the ovary: a rare consequence of torsion in a mature cystic teratoma

Autoamputation of the ovary may be a result of longstanding infarction resulting from torsion of the ovarian pedicle. This entity may be confused with an ectopic or supernumerary ovary.  A proper detailed history taking is important to provide clues for diagnosis. We report a case of a young female patient diagnosed with autoamputation of unilateral ovary on laparoscopy, with histopathology confirmation of ovary with dermoid cyst.
