Abstract:RESUMENAntecedentes: Los tumores adenomatoides (TA) son poco frecuentes. Se encuentran principalmente en el aparato reproductor femenino y especialmente en el útero. No existen reportes a nivel nacional sobre estos. Objetivos: Describir las características histológicas e inmunohistoquímicas de los TA uterinos. Método: Estudio descriptivo de 32 muestras ingresadas al Servicio de Anatomía Patológica de Clínica Las Condes. Las muestras estudiadas fueron recopiladas entre noviembre de 1999 y noviembre de 2008.

“…1) Angiomatoide: formación de espacios pseudovasculares revestidos por células planas o cúbicas bajas, sin elementos sanguíneos, con descamación luminal aislada de células de aspecto mesotelial; 2) Adenoide: formaciones de aspecto glandular formado por células cúbicas altas; 3) Formaciones sólidas: compuestas por cordones de células epitelio-des sin patrón específico y 4) quístico: formaciones quísticas, habitualmente subserosas, uni o multiloculares revestidas por células cúbicas o planas de aspecto mesotelial 7,8 . El estudio inmunohistoquímico incluye positividad en porcentajes variables para: Citoqueratina AE1/AE3, Citoqueratina 5/6, Calretinina, D2-40, WT-1 y CAM 5.2 1,6,8 .…”
adenomatoid pleural tumor introduction: Adenomatoid tumors are rare benign neoplasms, pleural is a very rare location, reporting only 4 cases worldwide and none in our country. case report: A 30 year-old female patient, that in the context of a preventive health examination, presents a mediastinal solid mass in the right hemithorax, in the thorax radiography. The lesion of 8 cm x 7 cm x 2.4 cm was surgically removed. Histology shows a lesion compatible with pleural adenomatoid tumor and inmunohistochemistry is positive for markers such as calretinin and cytokeratin 5/6. discussion: The pleural adenomatoid tumor is an uncommon neoplasm with benign behavior and several differential diagnoses.

“…The ABO system has four main groups that as A, B, AB and O and these are due to the presence of antigens A and B, for O there is no antigen. These antigens are controlled by three allelic genes A, B, and O that are present on the long arm of chromosome 9 (Conteras, 2001;Knowles, 2002). In addition, there is also present antigen H which is a precursor to A and B antigen but not stated as recognizable antigen on red blood cells (Brown et al, 1992).…”
The present study was conducted to find out the relative abundance of ABO blood groups and Rh factor in male population in three tehsil of district Karak namely Tehsil Karak, Tehsil Takht E Nasrati and Tehsil Banda Daud Shah. The blood groups and Rh factor ascertainment was find out through antigen-antibody clotting test. Total of 645 blood groups were checked of unknown people in a blood checking camp. The blood group B + was found to be most abundant in the whole district with relative abundance of 207 donors and percentage of 32.09% followed by O + (159, 24.65%), A + (141, 21.86%) and AB + (63, 9.76%). The Rh + was more abundant with 570 donors and percentage of 88.37% and Rhhas 75 donors and percentage of 11.62%. The blood groups with Rhare A -(26, 4.03%), B -(25, 3.87%), AB -(12, 1.86%) and O -(12, 1.86%).
