Expansive Oral Giant Cell Granuloma in a Pediatric Patient.

Aim: This article describes a peripheral oral giant cell granuloma (POGCG) in a pediatric patient and its surgical management and histological characteristics. Background: Peripheral oral giant cell granuloma (POGCG) is a hyperplastic reactive lesion formed by a proliferation of mononuclear cells and osteoclast-type giant cells in vascular tissue, occasionally with bone formation. Generally found in women and adults, POGCG has rarely been described in children. Case description: An 8-year-old girl was consulted for an exophytic lesion in the anterior area of the upper jaw, which had increased in volume in the preceding weeks. An excisional biopsy of the tumor was performed with an electrosurgical pencil. The pathological diagnosis was POGCG. Conclusion: Excision followed by additional therapy, such as scaling and curettage, should be the first option in the treatment of POGCG. Clinical significance: Early detection of these lesions involving the periodontium is important in order to reduce bone loss and avoid pathological dental migration.

Supratentorial neuroenteric cyst in children: a case report and brief literature review.

Neurenteric cysts are rare developmental lesions typically found outside the central nervous system but when they do, we most likely find them in a spinal (cervical or dorsal) intradural extramedular location, often associated with dysraphism. The more unusual intracranial cases have been published because of its rarity, occurring mostly as a posterior fossa extra-axial cyst, in adults. Supratentorial cases are distinctly infrequent, especially in children, resulting in few case reports and even fewer case reviews. We describe a case of a child with a supratentorial neurenteric cyst and present a brief review of the literature about these cysts in children, a noticeable gap in the literature.

Imaging Evaluation of Pediatric Parotid Gland Abnormalities.

Parotid gland lesions in children can be divided into benign or malignant. The age of the patient helps narrow the differential diagnosis, with vascular and congenital lesions being more frequent in the 1st year of life, while solid tumors are more frequent in older children. Inflammatory disease usually has rapid onset in comparison with that of neoplastic or congenital processes, which have more gradual clinical evolution. Currently, multiple imaging techniques are available to study the parotid region, such as US, CT, and MRI. However, it is still a challenge to distinguish nonmalignant lesions from malignant ones. US is the first-line diagnostic approach in children to characterize the morphology and vascularity of these lesions. CT in children may be indicated for evaluation of abscesses or sialolithiasis. MRI is the imaging modality of choice for investigating the nature of the lesion and its extent. In addition to complete and detailed clinical information, knowledge of parotid gland anatomy and characteristic radiologic features of parotid disorders is essential for optimal radiologic evaluation and avoiding unnecessary interventional diagnostic procedures or treatment. This article illustrates a variety of entities (congenital, inflammatory, vascular, neoplastic) that can occur in the parotid gland, highlighting the most frequent radiologic patterns of manifestation and correlating them with clinical, surgical, and pathologic findings. ©RSNA, 2018.

Second re-irradiation for DIPG progression, re-considering "old strategies" with new approaches.

Diffuse intrinsic pontine glioma (DIPG) is an aggressive infiltrative glioma for which no curative therapy is available. Radiation therapy (RT) is the only potentially effective intervention in delaying tumor progression, but only transiently. At progression, re-irradiation is gaining popularity as an effective palliative therapy. However, at second progression, exclusive symptomatic treatment is usually offered. Here we report two patients with DIPG at second progression who were treated with a second re-irradiation course with good response. Importantly, treatment was well tolerated with no irradiation associated acute toxicity identified.

Tumores de plexo coroideo en la infancia: experiencia en el hospital Sant Joan de Déu / Choroid plexus tumours in childhood: Experience in Sant Joan de Déu hospital

Los tumores de plexo coroideo son tumores raros, con un pico de incidencia en los 2 primeros años de vida. La localización más frecuente en niños es el ventrículo lateral, mientras que en adultos es el IV ventrículo. La manifestación clínica más común son los signos y síntomas de hipertensión intracraneal. Histológicamente se clasifican en papiloma de plexo, papiloma atípico de plexo y carcinoma de plexo. Realizamos una revisión de los tumores de plexo coroideo tratados en el Hospital Sant Joan de Déu entre 1980 y 2014. Se han tratado 18 pacientes. Analizamos datos demográficos, clínicos, histológicos, tratamiento recibido y recidivas. El tratamiento de elección es la resección completa, que se acompaña de tratamiento adyuvante en carcinomas. En papilomas atípicos es controvertido el uso de tratamientos adyuvantes, reservándose la radioterapia para las recidivas. Los papilomas tienen un buen pronóstico, mientras que en papilomas atípicos y carcinomas el pronóstico es peor

Choroid plexus tumours are rare, with a peak incidence in the first two years of life. The most common location is the lateral ventricle in children, while in adults it is the fourth ventricle. The most common clinical manifestation is the signs and symptoms of intracranial hypertension. They are histologically classified as plexus papilloma, atypical plexus papilloma, and plexus carcinoma. A review is presented on choroid plexus tumours treated in the Hospital Sant Joan de Déu between 1980 and 2014. A total of 18 patients have been treated. An analysis was made of the demographic, clinical, histological data, treatment, and recurrences. The treatment of choice is complete resection, accompanied by adjuvant therapy in carcinomas. In atypical papillomas, the use of adjuvant therapies is controversial, reserving radiation therapy for recurrences. Papillomas have a good outcome, whereas atypical papillomas and carcinomas outcome is poor
