Quadrigeminal cisterna lipoma: report of two cases and literature review / Lipoma da cisterna quadrigeminal: relato de dois casos e revisão da literatura

Intracranial lipomas are congenital, benign and slow-growing tumors. The incidence were 0.1 to 0.5 percent of all primary brain tumors and are often diagnosed in incidental findings of neuroradiological investigation. Lipoma in quadrigeminal region occurs in 25 percent of intracranial lipomas and has been reported as lipomas in quadrigeminal cistern (perimesencephalic cistern), quadrigeminal plate, ambiens cistern or superior medullary velum. MRI is the most major exam. The treatment is conservative in most cases, surgical removal is hampered by their deep location and contiguous with adjacent neurovascular structures. The authors report two cases of lipoma in the quadrigeminal region, incidental findings and discuss the clinical findings, neuroimaging and treatment.

Lipomas intracranianos são tumores congênito, benigno e de crescimento lento. Sua incidência é de 0.1 a 0.5 por cento de todos os tumores cerebrais primários e são frequentemente diagnosticados em achados incidental de investigação neuroradiológica. Lipoma na região quadrigeminal ocorre em 25 por cento dos lipomas intracranianos e tem sido relatados como lipomas na cisterna quadrigeminal (cisterna perimesencefálica), placa quadrigeminal, cisterna ambiens ou véu medular superior. O exame de eleição é ressonância magnética. O tratamento é conservador na maioria dos casos, a remoção cirúrgica é dificultada pela sua localização profunda e da contiguidade com estruturas neurovasculares adjacentes. Os autores relatam dois casos de lipoma na região quadrigeminal achados incidentalmente e discutem os achados clínicos, imagem e tratamento.

A Huge Lipoma of the Floor of the Mouth: An Unusual Case Report.

Lipomas of the oral cavity are not uncommon, but its location in the floor of the mouth is a rare entity. They are soft tissue mesenchymal neoplasm’s of mature adipose tissues. Its overall incidence of occurrence in the oral cavity is 1-5% of all benign oral lesions. Oral lipomas can occur at various anatomic sites, including buccal mucosa, tongue, major salivary glands, and floor of the mouth. Although benign in nature their progressive growth may cause interference with speech and mastication due to the tumors’ dimension. In this article, the author reports an unusually large lipoma occurring in the floor of the mouth in a 44-year-old female patient. The present case is worth presentation considering the relative rarity with respect to the location and the size of the lesion.

Proteus syndrome: Clinical profile of six patients and review of literature.

OBJECTIVE: Proteus syndrome (PS) is characterized by patchy or segmental overgrowth and hyperplasia of multiple tissues and organs, along with susceptibility to development of tumors. Very few cases are reported in literature from developing countries. Due to certain overlapping features with other overgrowth syndromes, diagnosis is usually delayed. Our aim was to describe clinical profile of this rare condition in six patients. MATERIALS AND METHODS: Retrospective case sheet review of patients followed in a Pediatric Genetic and Metabolic clinic at a tertiary care institute of North India with a diagnosis of hemihypertrophy/overgrowth syndrome. RESULTS: Six cases presented with asymmetric overgrowth and peculiar features suggestive of PS were included in this study. Age at presentation was 2 months to 10 years; two were males and four were females. Hemihypertrophy was noticed in only one case at birth, and focal overgrowths in rest of other patients were seen later during childhood. CONCLUSION: Due to certain overlapping features with other overgrowth syndromes, diagnosis of PS is usually delayed. Pediatricians are the first persons who come across such patients and they should be aware about this rare condition.

Lipoma in Floor of Mouth.

Lipomas are adipose mesenchymal neoplasms, they are relatively uncommon in the oral cavity, representing about 0.5% to 5% of all benign oral tumors1. The clinical presentation is typically as an asymptomatic yellowish mass. The overlying epithelium is intact, and superficial blood vessels are usually evident over the tumour. We report a case with an unusual and atypical presentation of the lipomas in the floor of mouth, which is quite a rare site in the literature even in the oral cavity lipomas.

Caracterización epidemiológica de los lipomas subcutáneos / Epidemiological characterization of subcutaneous lipomas

Introducción: Los lipomas son los tumores subcutáneos de tejido blando más comunes, con una incidencia de 1 por cada 1.000 personas. Se presentan generalmente entre los 40 y 60 años de edad. El objetivo de este trabajo fue realizar una caracterización epidemiológica de los lipomas subcutáneos. Metodología: Se realizó una búsqueda computacional sobre la base de datos del Servicio de Cirugía del Hospital Dipreca para localizar los pacientes operados con diagnóstico clínico de lipoma y luego se revisó el informe diferido de Anatomía Patológica. Resultados: La muestra estuvo conducida a 110 pacientes, correspondiendo 52% a sexo femenino. La edad de la muestra se concentró en un 65% entre los 40 y los 69 años. El 54% de los lipomas se localizaron en el tronco; de éstos destaca un 62% de localización en dorso, siendo la localización inguinal la menos frecuente. La biopsia diferida correspondió en un 72% de los casos a lipoma.

Introduction: Lipomas are the most common subcutaneous tumors of tender tissue, with an incidence of 1 in 1000 people. The greater incidence is between the ages of 40 and 60. The objective of this trial is to establish an epidemiologic description of subcutaneous lipomas. Methodology: A computational search of the Dipreca Hospital Surgery Department data base was carried out in order to locate patients diagnosed with lipomas that underwent surgery, and the correlation with pathology exams was reviewed. Results: 110 patients were studied, 52% women. 65% were between the ages of 40 and 69. 54% of the lipomas were located in the trunk, of which 62% were located in the back, being the groin the less affected area. Histopathology exams were conclusive of lipoma in 72% of cases.

Lipoma y angiolipomas: estudio clínico patológico, comparativo y retrospectivo en 260 pacientes / Lipomas and angiolipomas. Clinical and pathological study in 260 cases

Estudio clínico-patológico, comparativo y retrospectivo en 260 pacientes con lipomas y angiolipomas, en un periodo de 18 años. El 52.6 por ciento de los casos correspondieron a lipomas y el 47.3 por ciento a angiolipomas. A diferencia de los lipomas, los angiolipomas mostraron una mayor tendencia a presentarse como tumores múltiples y dolorosos, ocurriendo en individuos relativamente más jovenes

Tumores de piel: correlación clínico-patológica

Se presenta un estudio de 504 casos de tumores de la piel en la ciudad de Neiva, en un periodo de 28 meses. Los tumores benignos son más comunes en personas jovenes (71 por ciento), con edad promedio de 33 años; de ellos los más frecuentes son el nevus melanocítico (12 por ciento), Los lipomas (10 por ciento) y los hemangiomas (7 por ciento).
