Reporte de caso: poliquistosis parotídea (Adenosis poliquística esclerosante asociada a Enfermedad poliquística disgenética)

Introducción: La adenosis/adenoma poliquistico esclerosante (SPA) es aceptada como una nueva entidad neoplásica benigna muy poco frecuente de las glándulas salivales que compromete por lo general la glándula parótida. La enfermedad poliquística disgenética es otra entidad poco común con histología similar a la SPA y que también afecta a la gládula parótida con mayor frecuencia. Reporte de caso: Se presenta el caso de una mujer 28 de años con aumento de volumen de la glándula parótida derecha de aproximadamente 3 años de evolución cuyo análisis histopatológico sugirió el diagnostico de Adenosis/adenoma Poliquístico Esclerosante asociado a Enfermedad Poliquística Disgenética de la glándula parótida derecha. La paciente recibió tratamiento quirúrgico de parotidectomía total con preservación del nervio facial. Al momento con remisión de la enfermedad.

Introduction: Polycystic sclerosing adenosis / adenoma (SPA) is accepted as a very rare new benign neoplastic entity of the salivary glands that generally involves the parotid gland. Dysgenetic polycystic disease is another rare entity with histology similar to SPA and that also affects the parotid gland more frequently. Case report: The case of a 28-year-old woman with increased volume of the right parotid gland of approximately 3 years of evolution is presented, whose histopathological analysis suggested the diagnosis of Polycystic Sclerosing Adenosis / adenoma associated with Polycystic Dysgenetic Disease of the right parotid gland. The patient received surgical treatment of total parotidectomy with preservation of the facial nerve. At the moment with remission of the disease.

Linfangiomatosis esplénica en un paciente adulto: Reporte de caso

Los linfangiomas son malformaciones benignas del sistema linfático que afectan con mayor frecuencia a los niños y en raras ocasiones a adultos. Presentamos el caso de una mujer de 36 años, con cuadro clínico de 6 meses de dolor abdominal difuso sin irritación peritoneal, y asociado a adinamia. Como parte de los estudios, se solicitó una tomografía axial computarizada con contraste de abdomen, que reveló múltiples lesiones esplénicas hipodensas hipovasculares, con sospecha diagnóstica de lesiones linfoproliferativas. Por tal motivo se solicitó una esplenectomía diagnóstica, que finalmente mostró hallazgos macroscópicos, microscópicos y de inmunohistoquímica (positividad de las lesiones quísticas para CD31 y D2-40) compatibles con linfagiomatosis esplénica difusa.

Lymphangiomas are benign malformations of the lymphatic system. They most often affect children and rarely adults. We present the case of a 36-year-old woman with a 6-month clinical picture of diffuse abdominal pain without peritoneal irritation associated with adynamia. As part of the studies, a computerized axial tomography with abdominal contrast was requested, which revealed multiple hypovascular hypodense splenic lesions with suspected diagnosis of lymphoproliferative lesions. For this reason, a diagnostic splenectomy was requested, which showed macroscopic, microscopic and immunohistochemical findings (positivity of cystic lesions for CD31 and D2-40) compatible with diffuse splenic lymphagiomatosis

Epithelioid hemangioma of the ascending aorta: A rare case

Cardiac epithelioid hemangioma is extremely rare. Currently, there are only a few described cases of intraluminal hemangiomas of the aorta and the aortic valve and no described cases with extraluminal epithelioid hemangiomas of the ascending aorta. We now present a case of epithelioid hemangioma of the ascending aorta that was an incidental finding during the coronary artery bypass and successfully resected.

Extensive Giant Lipoma of Oropharynx

@#Lipoma is a benign, slow growing tumour composed of adipose tissue. In general, it is very unusual for lipoma to form in the head and neck region, let alone achieve a size of more than 10 cm with the involvement of deep neck spaces. We discussed a case of an extremely huge neck lipoma measuring 18 cm x 14 cm with extensive involvement of deep neck spaces, infratemporal fossa and pharynx, closely adherent to submandibular and parotid gland. The diagnostic and therapeutic challenges were discussed, in achieving a surgically complete excision and cosmetically acceptable outcome

Hemangioma cavernoso / Cavernous Hemangioma

El hemangioma cavernoso es una neoplasia benigna de los vasos sanguíneos. Este trabajo tuvo como objetivo presentar el caso de un hemangioma cavernoso gigante que fue tratado con propranolol. El diagnóstico se realizó mediante examen físico, dúplex y otros complementarios de interés. Para la decisión de la conducta terapéutica, especialistas de diferentes especialidades evaluaron al paciente: Oncología, Dermatología, Ortopedia, Pediatría y Angiología. Una vez establecido el tratamiento, se realizó un seguimiento durante cuatro semanas y luego mensual. El resultado, después de 22 meses, fue la desaparición del hemangioma. El propranolol en el hemangioma cavernoso gigante debe ser el tratamiento de elección precoz para una evolución satisfactoria y evitar complicaciones(AU)

Cavernous hemangioma is a benign neoplasm of blood vessels. This work aimed at presenting the case of a giant cavernous hemangioma treated with propranolol. The diagnosis was made by physical examination, duplex Doppler sonography, and complementary tests of interest. For deciding the therapeutic approach, the patient was assessed by several specialists from different medical fields, such as oncology, dermatology, orthopedics, pediatrics, and angiology. Once the treatment was established, a follow-up was carried out for four weeks and then monthly. The outcome, after twenty-two months, was the hemangioma disappearance. Propranolol in giant cavernous hemangioma should be the treatment of early choice for a satisfactory evolution and to avoid complications(AU)

Diagnosis and treatment of bladder benign neoplasm in children / 中华泌尿外科杂志

Objective To summarize the experience about the diagnosis and treatment of bladder benign neoplasm in children.Methods A retrospective study was conducted for a total of 15 patients with bladder benign neoplasm from October 2006 to May 2016.There were 10 males and 5 females with a mean age of 8.7 years (ranging 1.1-13.8 years).The clinical manifestations of 15 patients included hematuria in 9 patients,frequent micturition with urgent and painful in 3 patients,dysuria in 1 patient,abdominal pain in 2 patients and headache during voiding in 1 patient.Ultrasound showed solid masses in the bladder with iso-echoic or nonhomogeneously hypoechoic.CT scanning showed regular or irregular mass with some enhancement in the bladder.All cases received tumor complete resection by opening operation and bladders were preserved.Among the 15 cases,neoplasms located in the anterior,posterior and lateral wall of bladder in 9 cases,ureteral orifice in 4 cases and trigone of bladder in 2 cases.The size of tumors ranged from 1.2 to 6.0 cm (mean 3.1 cm).The tumors were unifocal and seemed like papillary or cauliflower.The literatures of benign neoplasm of bladder were reviewed,which focused on the clinic characters,pathological classification and therapeutic method.Results Pathologic type included papilloma in 5 patients,inverted papilloma in 1 patient,inflammatory myofibroblastic tumor in 7 patients,hemangioma in 1 patient,pheochromocytoma in 1 patient.Fifteen patients were followed up for 6 to 36 months,mean 26.7 months.All patients recovered well without relapse or metastasis Conclusions Bladder benign neoplasm in children is rare with many kinds of pathological classification.The major clinical manifestation is gross hematuria while dysuria is unusual.Tumors are fewer in trigone of bladder.The best treatment is to resect the tumor completely with bladder preservation if possible.

Recurrent Peripheral Odontogenic Fibroma: A Case Report with the Review of Literature

Peripheral odontogenic fibroma (POF) is a rare benign mesenchymal odontogenic neoplasm with or without odontogenic epithelium, which is considered to be the mucosal analogue of central odontogenic fibroma. Though peripheral odontogenic tumours are rare, comprising of only 0.05% of all biopsy specimens, POF is the most common peripheral odontogenic tumour, more common than its central counterpart by a ratio of 1.4: 1. In this report, we describe a healthy 40-year-old female who was seen with a recurrent POF of the left mandible.

Tumor condrolipomatoso (condrolipoma) de mama / Chondrolipoma of the breast

Introduction: Cartilage is an uncommon component in breast lesions, most of cases it correspond to metaplasia of malignant neoplasm and its occurrence in benign tumors is exceptional. Cartilage- containing breast benign tumors has been subclassified by their majors features accord to each author, but their main composition remains to be adipose tissue, fibrous stroma and cartilage, with or without breast epithelium. Chondrolipoma of the breast was reported for the first time by Kaplan in 1977, and since then reports of this entity has been anecdotal with less than 20 cases published. Clinical case: We expose the first case diagnosed of chondrolipoma of the breast in Colombia, performed on the Pathology Department of Universidad Industrial de Santander (Bucaramanga-Colombia) along with a literature review, due to the low frequency of this diagnosis and the few information about it.

Introducción: El cartílago es un componente poco común en las lesiones de mama, la mayoría de casos corresponden a metaplasias de lesiones malignas siendo excepcional el hallazgo en lesiones benignas; estas últimas se han subclasificado de acuerdo a las características histológicas destacables para cada autor, pero globalmente se componen de tejido adiposo, estroma fibroso y cartílago, mientras que el componente epitelial mamario es de presentación variable. El condrolipoma de mama fue reportado por primera vez en 1977 por Kaplan y desde esa fecha los reportes han sido anecdóticos con menos de 20 casos publicados. Caso clínico: Se expone el primer caso diagnosticado en Colombia de condrolipoma de mama, diagnóstico efectuado en el Departamento de Patología de la Universidad Industrial de Santander (Bucaramanga-Colombia) y se hace una revisión de la literatura de esta entidad, dada la baja frecuencia de su diagnóstico y a la escasa información al respecto.

Adenomatoid Odontogenic Tumor: A Case Report.

Adenomatoid odontogenic tumor (AOT) is a very rare odontogenic tumor with an incidence of 1%. Overall it accounts for 9% of all odontogenic tumors. In most of the cases, AOT is misdiagnosed as an odontogenic cyst. Younger individuals are commonly affected and particularly in females. AOT is seen predominantly in the maxillary anterior region in association with an unerupted tooth. Permanent dentition is affected more than the deciduous dentition. Intraoral periapical radiographs play a major role in the diagnosis compared to orthopantomogram because of its increased contrast but for the better assessment of the extension of larger lesions orthopantomogram is must. AOT resembles benign odontogenic lesions like dentigerous cyst and tumors like ameloblastoma. The lesions are managed conservatively by surgical excision along with the removal of the affected tooth and have an excellent prognosis.With this background, we report an unusual case of AOT involving maxillary anterior region in 15-year-old male patient. The present article reviews the etiology, clinical features, histopathological features, and treatment modalities of AOT.

Myopericytoma of lip: A rare lesion in an unusual location.

Myopericytoma is a rare benign tumor with perivascular myoid differentiation. It shares histomorpholoic features with the so-called hemangiopericytoma, myofi broma and glomus tumor. We hereby report the case of a 14-year-old boy who presented with a slowly growing, painless, fi rm mass on upper lip, diagnosed as myopericytoma on the basis of histopathology and immunohistochemistry. To the best of our knowledge, this is only the second such reported case.

Reactive Lymphoid Hyperplasia Treated with Radiofrequency Ablation / 대한내과학회지

Reactive lymphoid hyperplasia (RLH) is a rare benign liver mass that is characterized by proliferation of non-neoplastic lymphocytes extranodally. To date, only 43 cases have been reported in the English literature and 2 cases in the Korean literature. We report a case of hepatic RLH in a 36-year-old woman who had been diagnosed two years previously with an intrahepatic tumor that measured 0.6 x 1.0 cm on abdominal ultrasonography. Her medical history was otherwise unremarkable. On follow-up ultrasonography, the hepatic mass had increased in size. We biopsied the liver mass and the histopathologic findings confirmed reactive lymphoid hyperplasia. Radiofrequency ablation (RFA) was performed instead of surgical resection. The patient is currently doing well with no sign of relapse 1 year and 8 months after the RFA.

A Case of Benign Meningioma Presented with Subdural Hemorrhage

Meningiomas are the most common benign intracranial tumors and make up 13-26% of all primary intracranial tumors. Clinical presentation of hemorrhage is rare in these tumors occurring in approximately 1.3% of cases and subdural hemorrhages are even more uncommon. The mechanism of hemorrhage is still unclear and may vary according to histologic type, location and the type of hemorrhage. We experienced a case of 61-year-old woman with a benign meningioma presenting as a subdural hemorrhage. She developed sudden onset of headache right after aggressively coughing. Her headache persisted for a week before she was admitted to the emergency room of National Cancer Center. She had a past medical history of ovarian cancer which had been treated and was allegedly recurrence-free for 2 years. At the time of admission, a headache was the only symptom and imaging studies showed a right frontal hemorrhagic subdural mass lesion accompanying an ipsilateral subdural hematoma. Elective surgery was performed and intraoperative findings revealed the hallmark characteristics of a meningioma with mixed stage diffuse subdural hematoma. Permanent pathology result determined it was a conventional meningioma (World Health Organization grade I). From this case, we discuss the rare presentation of subdural hemorrhage in meningioma and related points by reviewing the literature of previous studies.

Erector Spinal Muscular Schwannoma of the Dorsal Ramus Nerve: A Case Report

We present a rare case of intramuscular schwannoma originating from the dorsal ramus nerve in a 62-year-old woman. The mass grew slowly, with pain developing upon touch five years prior. No neurological deficit was detected. The mass was observed in the erector spinae muscles in magnetic resonance imaging (MRI), and surgical excision was performed. The mass was well encapsulated with clear margin. The lesion appeared to originate from the cranial side. We completely removed the mass including the origin. Histopathology confirmed a schwannoma diagnosis. This is the first report, to our knowledge, of a dorsal ramus-nerve schwannoma within the erector spinae muscles.

Adenoma pleomórfico: características clínicas e protocolo diagnóstico / Pleomorphic adenoma: clinical features and diagnostic protocol

O presente estudo teve como objetivo analisar o adenoma pleomórfico (AP) em sua integralidade, buscando expor ao cirurgião-dentista os melhores métodos de diagnóstico e tratamento. Revisão de literatura: o AP é a mais comum neoplasia benigna de glândulas salivares. Acredita-se que o AP seja derivado de uma mistura de elementos ductais e mioepiteliais. Apresenta predileção pelo sexo feminino e pela faixa etária dos 30 aos 60 anos. Localiza-se mais comumente nas glândulas parótidas, seguidas das submandibulares e salivares menores. Apresenta como manifestação clínica um aumento de volume firme, indolor e de crescimento lento. Os métodos de diagnóstico auxiliares são: sialografia, ultrassonografia, tomografia computadorizada, ressonância magnética, mas o diagnóstico definitivode AP é dado pela realização do exame histopatológico. O tratamento para a lesão consiste na sua exérese, por vezes, com parte da glândula afetada. O prognóstico da lesão é favorável, porém apresenta uma complicação potencial que é o risco de malignização. Relato de caso: no presente estudo relatou-se um caso de AP em paciente leucoderma, feminino, 36 anos de idade, apresentando tumefação firme, assintomática de superfície lisa, no lado direito do palato duro, medindo aproximadamente 3 cm. Foi realizada biópsia incisional do caso e o exame histopatológico confirmou o diagnóstico de AP. Devido à extensão da lesão, a paciente foi encaminhada para realizar a remoção cirúrgica com cirurgião de cabeça e pescoço. Conclusão: apesar de relativamente comum, o AP pode atingir grandes dimensões, devendo o cirurgião-dentista realizar seu diagnóstico e realizar o correto encaminhamento para profissional da área médica...

This study aimed to analyze the pleomorphic adenoma (PA) in its entirety, seeking to expose the dentist the best methods of diagnosis and treatment. Literature review: the PA is the most common benign tumor salivary glands. It is believed that the PA is derived from a mixture of myoepithelial and ductal elements. It is more prevalence among females and in the age group 30 to 60 years. It located most commonly in the parotid, followed by the submandibular and then the small glands. The clinical manifestation is a localized increase of size, firm, painless and of slow growth. Auxiliary diagnostic methods are: sialography, ultrasonography, computed tomography, magnetic resonance, but the definitive diagnosis of PA is given by the completion of the histopathological examination. Excision is the treatment for the lesion sometimes including part of the affected gland. The prognosis of the injury is favorable, but it presents a potential complication that is the risk of malignancy. Case report: it is reported a case of PA in a Caucasian patient, female, 36 years old, with firm swelling, asymptomatic, smooth surface on the right side of the hard palate, measuring approximately 3 cm. Incisional biopsy was held and histopathological examination confirmed the diagnosis of PA. Due to the extent of the injury, the patient was referred for surgical removal with head and neck surgeon. Conclusion: although relatively common, the PA can reach large size. Therefore, the dentist should confirm the diagnosis and correctly referrer the case to surgical treatment...

Unicystic Ameloblastoma Involving the Mandible: A Case Report

Unicystic ameloblastoma (UA) refers to those cystic lesions that show clinical, radiographic, or gross features of a mandibular cyst, but on histological examination show a typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumour growth. UA is believed to be the less aggressive than the solid or multicystic ameloblastomas. We present a case report of 40 year old male patient with UA involving the entire body of the mandible.
