Caracterización clinicopatológica del melanoma uveal / Clinical and pathological characterization of uveal melanoma

Objetivo: Describir las características clinicopatológicas de los pacientes con diagnóstico de melanoma de la úvea. Métodos: Se realizó un estudio descriptivo y retrospectivo de serie de casos, en el Instituto Cubano de Oncología y Radiobiología de Cuba, desde enero del año 2011 hasta junio de 2016. El universo del estudio, en coincidencia con la muestra, estuvo constituido por 41 pacientes, el total de ellos diagnosticado y tratado en dicho período por melanoma uveal. Se estudiaron las variables edad, sexo, lateralidad, localización y tamaño tumoral, clasificación, tipo celular, grado de invasión y tratamiento. Resultados: El 56,1 por ciento de la muestra fue del sexo femenino. Los pacientes mayores de 50 años (75,6 por ciento) fueron los más afectados y el ojo izquierdo fue el más vulnerable (58,5 por ciento). La principal localización fue en la coroides (75,6 por ciento). Según el tamaño tumoral predominaron los tumores grandes (58,5 por ciento); histológicamente el tipo celular más frecuente fue el de células fusiformes (34,2 por ciento); según el grado de invasión, la más afectada fue la esclera (17,0 por ciento) y como único tratamiento practicado la enucleación (100 por ciento). Conclusiones: El melanoma de la úvea tiene su localización más frecuente en la coroides. Se presenta principalmente en pacientes mayores de 50 años y predominan los tumores grandes(AU)

Objective: To describe the clinical and pathological characteristics of patients diagnosed with uveal melanoma. Methods: A retrospective, descriptive and case series study was performed from January 2011 to June 2016 in the Institute of Oncology and Radiobiology of Cuba (INOR). The universe of study was the sample of 41 patients, all of them diagnosed with uveal melanoma and treated in this period of time. The study variables were age, sex, laterality, tumor location and tumor, classification, cell type, degree of invasion and treatment. Results: Females accounted for 56.1 percent of the sample. The patients aged 50 years or over (75.6 percent) were the most affected whereas left eye was the most vulnerable (58.5 percent). The main location were the choroids (75.6 percent) According to size, the large tumors predominated (58.5 percent); from the histological viewpoint, the most common cell-type was fusiform cell tumor (34.2 percent); according to the degree of invasion, the sclera was the most affected (17 percent) and the only treatment was enucleation. Conclusions: Uveal melanoma is more frequently located in the choroids. It mainly appears in patients aged over 50 years and most of tumors are large(AU)

Manifestation of fundus angiograph of polypoidal choroidal vasculopathy / 中华眼底病杂志

Objective To observe the manifestation of fundus angiographs of polypoidal choroidal vasculopathy (PCV). Methods Twelve PCV patients involved 7 males and 5 females aging from 40 to 69 year old (average 56.4). Fundus examination, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were performed on 12 patients (12 eyes) with PCV, out of whom 5 underwent optical coherenece tomography (OCT). Results In 12 eyes, deep and (or) superficial hemorrhage and yellow hard exudations were found, including orange-red lesions in 6 and pre-retinal hemorrhage in 2. The results of FFA discovered orange-red spotty fluorescence in 6 eyes and choroidal vascular network in 4 eyes. At the late phase, leakage of polypoidal hyperfluorescence spot in all of the eyes except 2 without leakage were found. The images of ICGA showed typical dotted or clustered polypoidal hyperfluorescence in 12 eyes at the late phase. OCT disclosed protrusion of the retinal pigment epitelium (RPE) with a bumpy surface at polypoidal structure in 4 eyes and no change in 1 eye. Conclusions PCV mainly affects the elderly persons and mostly on unilateral eyes. Macular hemorrhage, serous RPED, and (or) neuroepithelial detachment with yellow hard exudations are the main manifestations. Branching choroidal vascular net with ployplike terminal anourysmal dilations can be discovered in FFA and ICGA.

Indocyanine green and fundus fluorescein angiography in anterior ischemic optic neuropathy / 中华眼底病杂志

Objective To observe the characteristics of indocyanine green angiography and fundus fluorescein angiography (ICGA& FFA) in anterior ischemic optic neuropathy ( AION ) , and to investigate the etiology of AION and the value of ICGA and FFA in the diagnosis and study of AION. Methods Simultaneous ICGA and FFA were performed on 32 eyes of 31 AION patients and 38 eyes of 38 non AION patients. Results The eyes that all or a part of the optic disc lies in the watershed zones of the choroidal blood supply were significantly more in the AION group than those in the non AION group (P

Surgical Outcome of Choroid Plexus Tumors in Adults : Experience of 5 Cases

A retrospective analysis of five adult patients with choroid plexus tumor(four choroids plexus papillomas, one choroids plexus carcinoma who underwent surgical resection at our institute between February 1991 and October 1995 was performed. The study group included two males and three females with a mean age of 34.0 years(range 21 to 24 years). Two of four choroids plexus papillomas were removed gross totally and one of these was irradiated postoperatively. The remaining two patients with choroids plexus papilloma underwent a subtotal surgical resection and one of them received radiation therapy. During follow-up, the authors could not find any difference in the size of the residual tumor or in the patient's KPS between the irradiated groups. There was also no response to postoperative radiation therapy in a patient with choroids plexus carcinoma who underwent a subtotal resection. The author's clinical experiences suggest that the use of radiation therapy in adult patients with choroids plexus tumor is not effective, and thus gross total resection should be attempted during the primary operation of such tumors.

Malignant melanoma of the choroid.

Two cases of the malignant melanoma of the choroids were revealed from the in-patient section, Department of Ophthalmology, Siriraj Hospital, from 1978 to 1986. This is a rare disease and frequently found in the white patient rather than in the black. The first case was male and the second case was female. The age was 35 and 33 years respectively one of them came from the Northern province. The presenting symptom was the same (blurring of vision about 2 months). On the eye examination, found secondary retinal detachment from the underlying intraocular tumour both of them. Enucleation was done in both cases. The pathologic whole eye section was confirmed microscopically the malignant melanoma of the choroids with secondary retinal detachment.
