ABSTRACT

To evaluate the sensitivity and specificity of Calretinin and Carcinoembryonic antigen as immunocytochemical markers in distinguishing mesothelial cells from metastatic adenocarcinoma cells in effusion cytology. This study included 50 patients who presented with effusions [26 pleural and 24 peritoneal], at Al-Kadhimya Teaching Hospital who were selected according to their preliminary diagnosis from 1[st] December 2010 to 30[th] June 2011. Effusion fluids were aspirated and processed for both conventional cytological methods using Papanicolaou-stain and immunocytochemical staining with anti Calretinin and Carcinoembryonic antigen. The sensitivity of cytology for detection of malignant cells was 77%, with 100% specificity and 86% accuracy. Calretinin was observed to be a specific [100%] and sensitive [90%] marker for mesothelial cells [of benign etiology]. Carcinoembryonic antigen exhibited 70% sensitivity and 100% specificity for adenocarcinoma cells. When the results of both cytology and immunocytochemistry were considered in conjunction, the sensitivity for the detection of malignancy increased to 97%, with 100% specificity and 98% accuracy. Calretinin and Carcinoembryonic antigen were found to be useful markers for differentiating reactive mesothelial cells from metastatic adenocarcinoma cells in smears prepared from body fluids. Also, the combination of both cytology and immunocytochemical studies using the two markers can greatly enhance the diagnostic accuracy, sensitivity and specificity in malignant effusions.

ABSTRACT

Comunicamos el caso de un paciente masculino de 58 años, con antecedente de mesotelioma maligno en tratamiento oncológico, quien presentó un tumor en el espacio retrorrectal el cual fue operado, constatándose posteriormente metástasis de mesotelioma. Debido a la infrecuencia del caso se realiza una revisión de la literatura médica nacional e internacional actualizada sobre el tema.


We report a case of a 58 year old male patient, wilh a malignant mesothelioma, with oncological treatment, who presented a tumor in the space retrorectal which was operated. Afterwards it was found out as a metastasis of that lesion. Duc to the infrequency of the case, a revision of the latest national and international medical literature was done.

ABSTRACT

Wandering spleen is the consequence of excessive splenic mobility due to ineffective peritoneal attachment, rarely associated to splenic cysts. In cases previously reported, splenic cysts are mostly pseudocystic formations from trauma, infarction or parasitic disease. True cysts, epithelial or mesothelial lined, which are considered dysontogenetic formations, are usually not associated to wandering spleen. Angiomyolipoma is a benign triphasic tumor, usually renal. Few cases of wandering spleen associated with mesothelial cyst or angiomyolipoma are described. We present the first case to our knowledge of these three entities together; isolated evidence, once compiled, may lead to the influence of estrogen as a common factor in pathogenesis. Even though a punctual intervention in a benign panorama, we question whether these lesions act as distinct, partially associated or as the manifestation of an underlying silent syndromic disease that could harbor future outcomes to similar patients.

ABSTRACT

Differentiation of benign from malignant mesothelial proliferations is a major problem in the pathology of the serosal membranes, particularly in small biopsy specimen. This study was conducted for the evaluation of proliferative marker for distinction between malignant mesothelioma [MM] and mesothelial hyperplasia [MH]. Thirty six cases of malignant mesothelioma [MM] with the mean age of 62.94 years [range: 36-80 years, M/F: 3.58] and 22 cases of mesothelial hyperplasia [MH] were evaluated for proliferative status by immunohistochemical [IHC] method with monoclonal antibody, Ki-S5 [Ki-67]; the labeling indices [LI] were evaluated. Average count revealed a significant increase in MM as compared with reactive MH [p value < 0.0001]. Considering a threshold of 9% for ki-67, a sensitivity of 88% and specificity of 94% were resulted. Proliferative marker of Ki-67 can be useful in distinction between malignant mesothelioma and mesothelial hyperplasia [p-value < 0.0001]

ABSTRACT

El mesotelioma pleural benigno, localizado y pediculado (MPBLP) es un tumor primario de pleura, raro, que suele ser un hallazgo radiológico presentándose como una masa densa bien definida que modifica su ubicación con los cambios de decúbito del paciente y con la respiración. El presente trabajo tiene por objeto desarrollar sus principales características clínicas, radiológicas y patológicas, con el fin de incluirlo dentro de los diagnósticos diferenciales de una masa intratorácica móvil

ABSTRACT

Introducción: El mesotelioma pleural maligno (MPM) es una neoplasia casi invariablemente fatal, relaciónada la gran mayoría de las veces con la exposición a asbesto. La frecuencia de aparición de MPM es creciente en el mundo entero y, en nuestro país su aumento es alarmante. Sin embargo, hay pocos estudios que describan la experiencia con esta entidad en nuestro medio. Objetivo: Presentar la experiencia del Instituto Nacional de Cancerología de Santafé de Bogotá en MPM. Diseño: estudio observacional descriptivo (serie de casos) Pacientes y Métodos: se revisaron los registros de pacientes con diagnóstico de MPM entre 1935 y 1994. Se escogieron 32 que tuvieron la información requerida. Las variables seleccionadas fueron analizadas estadísticamente por los métods de chi cuadrado, T de student, Kaplan-Meier, Log-Rank-Test y Cox. Resultados: Se diagnósticaron 32 pacientes con Mesotelioma Pleural Maligno. Veintidós (69 por ciento), consultaron en los últimos 6 años; fueron 24 hombres y 8 mujeres (relación 3:1), con edad promedio de 46,5 años (rango 6-76 años). El tiempo promedio de evolución de los síntomas fue de 8 meses (rango 1-72 meses). Se presentó disnea en 22 (69 por ciento) pacientes, dolor torácico en 21 (66 por ciento)y tos en 17 (53 por ciento). Todos presentaron alteraciones radiológicas: 27 derrames pleurales, 24 engrosamientos pleurales y 9 masas. Se definió, si hubo o no exposición a asbesto en 18 pacientes; 14 estuvieron expuestos (78 por ciento). La broncospía y citología del líquido pleural nunca confirmaron el diagnóstico. La biopsia pleural ciega detectó malignidad, pero sólo confirmó el diagnóstico en 2 de 21 pacientes (9,5 por ciento). Las biopsias por toracoscopia o cirugía, siempre permitieron el diagnóstico. Histológicamente fueron 16 epiteliales (51,6 por ciento) 8 mixtos (25.8 por ciento) y 7 sarcomatosos (22,6 por ciento); Veintiocho (90,3 por ciento) fueron difusos. Diez pacientes se consideraron en estado I (34,5 por ciento) y 14 en estado II (48,3 por ciento). Cirugía radical se realizó en 11, con una mortalidad operatoria de 2 (8 por ciento), y una morbilidad de 4 (16 por ciento). Radioterapia se administró a 11 pacientes y quimioterapia a 7. El tiempo libre de enfermedad promedio fue 37,9 meses (rango 1-137), el cual se disminuye a 14,1 meses si excluimos al paciente que duró 137 meses. este tiempo fue influido si la cirugía fue o no...
