RESUMEN Introducción: la función del endometrio está regida por el eje hipotálamo hipofisario mediante las hormonas sexuales por lo que es vulnerable a los desórdenes de este sistema los que provocan diferentes trastornos funcionales que se traducen en alteraciones morfológicas. Es fundamental su estudio para el diagnóstico de patologías que son un problema de salud en la población femenina. Objetivo: determinar las diferencias morfométricas para el diagnóstico histopatológico diferencial entre la hiperplasia endometrial compleja, el adenocarcinoma endometrioide y en el endometrio proliferativo normal, en el municipio Matanzas, enero2014 -2015. Material y Métodos: se realizó un estudio observacional descriptivo de corte transversal y se aplicó morfometría a una muestra de 30 biopsias endometriales, con el objetivo de determinar las diferencias morfométricas para el diagnóstico histopatológico diferencial entre la hiperplasia endometrial compleja, el adenocarcinoma endometrioide y en el endometrio proliferativo normal. Resultados: el área total de la glándula fue la variable analizada que mostró mayores valores y reflejó marcadas diferencias entre la hiperplasia endometrial compleja, el adenocarcinoma endometrioide y el endometrio proliferativo normal, seguida por la altura del epitelio por tanto existen diferencias cuando se estudian variables que tiene en cuenta la morfología glandular. Conclusiones: existen diferencias morfométricas entre la hiperplasia endometrial y el adenocarcioma endometroide cuando se estudian variables que tienen en cuenta la morfología y arquitectura glandular (AU).

SUMMARY Introduction: the endometrium function is ruled by the pituitary- hypothalamus axis by means of sexual hormones; therefore it is vulnerable to the disorders of this system provoking different functional disorders resulting in morphological alterations. It is very important to study them for the sake of the diagnosis of diseases that are a health problem in female population. Objective: to determine the morphometric differences for the differential histopathological diagnosis among the complex endometrial hyperplasia, the endometrioid adenocarcinoma and the normal proliferative endometrium e, in the municipality of Matanzas, in the period January 2014-2015. Methods: a cross-sectional descriptive observational study was carried out applying morphometry to a sample of 30 endometrial biopsies, with the objective of determining the morphometric differences for the differential histopathological diagnosis among the complex endometrial hyperplasia, endometrial adenocarcinoma and normal proliferative endometrium. Results: the gland total area was the used variable showing more values and revealed stark differences among complex endometrial hyperplasia, endometrioid adenocarcinoma and normal proliferative endometrium, followed by the epithelium height; hence there are differences when variables are studied taking into account glandular morphology. Conclusions: there are morphometric differences between endometrial hyperplasia and endometrioid adenocarcinoma when there are studied variables taking into account glandular morphology and architecture (AU).

Introducción: el endometrio es fundamental para el diagnóstico de entidades que constituyen problemas de salud para la población femenina. Resulta de vital importancia para el patólogo el hallazgo de diferencias entre la morfología del endometrio de la hiperplasia endometrial y el adenocarcinoma endometrioide que le permitan realizar el diagnóstico diferencial ente estas dos entidades. Objetivo: determinar las diferencias morfométricas para el diagnóstico histopatológico diferencial entre la hiperplasia endometrial compleja, el adenocarcinoma endometrioide y en el endometrio proliferativo normal. Materiales y métodos: se realizó un estudio observacional descriptivo de corte transversal y se aplicó morfometría a una muestra de 30 biopsias endometriales, con el objetivo de determinar las diferencias morfométricas para el diagnóstico histopatológico diferencial entre la hiperplasia endometrial compleja, el adenocarcinoma endometrioide y en el endometrio proliferativo normal. Se utilizó sistema morfométrico IMAGEN J 1.44p, se estudiaron las glándulas endometriales a las que se les halló la altura del epitelio glandular. Resultados: la altura del epitelio en las glándulas de tamaño menor, intermedio y mayor, expresaron estrechas diferencias entre la hiperplasia endometrial compleja, el adenocarcinoma endometrioide y en el endometrio proliferativo normal y que existen diferencias entre la hiperplasia endometrial y el adenocarcinoma endometrioide cuando se estudian variables que tiene en cuenta la morfología glandular. Conclusiones: se concluyó que existen diferencias entre la hiperplasia endometrial y el adenocarcinoma endometrioide cuando se estudian variables que tiene en cuenta la morfología glandular (AU).

Introduction: the endometrium is fundamental for the diagnosis of entities that are a health problem for female population. It is very important for the pathologist to find differences between the morphology of the endometrium of the endometrial hyperplasia and the endometrial adenocarcinoma allowing to perform the differential diagnosis between these two entities. Objective: to determine the morphometric differences for the differential histopathological diagnosis between the complex endometrial hyperplasia, the endometrial adenocarcinoma and the normal proliferative endometrium. Materials and methods: a cross-sectional, descriptive, observational study was applied and the morphometry was applied to a sample of 30 endometrial biopsies, with the objective of determining the morphometric differences for the histopathological differential diagnosis among complex endometrial hyperplasia, endometrial adenocarcinoma and normal proliferative endometrium. The morphometric system IMAGEN J 1.44p was used and the endometrial glands were studied and the height of their glandular epithelium was calculated. Results: the minor, intermediate and higher height of the epithelium in the glands expressed tight differences among complex endometrial hyperplasia, endometrial adenocarcinoma and normal proliferative endometrium, and showed that there are differences between endometrial hyperplasia and endometrial adenocarcinoma when the studied variables take into account the glandular morphology. Conclusions: there are differences between endometrial hyperplasia and endometrial adenocarcinoma when there are studied variables taking into account the glandular morphology (AU).

Expression pattern of Aromatase Cytochrome P450 in Adenomyosis / 대한산부인과학회잡지

OBJECTIVE: To determine whether local estrogen production takes place in adenomyosis and in normal endometrium. METHODS: The study included 23 cases of adenomyosis and 17 cases of normal uterine endometrium obtained through hysterectomy or curettage at Kangnam Cha Hospital. The frozen tissue specimens were examined by immunohistochemistry using P450 arom. RESULTS: P450 arom was immunolocalized exclusively in the cytoplasm of glandular cells of adenomyotic tissue. However, no apparent staining was observed in stromal cells. Aromatase was expressed in the ectopic glands (82.6%), but also in the eutopic endometrium of patients with adenomyosis (23.5%). In the case of normal endometrium, P450arom was not detected. CONCLUSION: These results suggest that the aromatase activity is correlated to the pathophysiology of adenomyosis.

Expression of CD44 Variant 6 (V6) in endometrial cancer, endometrial hyperplasia, and normal endometrium / 대한산부인과학회잡지

OBJECTIVE: To compare the expression of CD44 V6 in normal endometrium, endometrial hyperplasia, and endometrial cancer and to evaluate CD44 variant 6 for prognostic marker. METHODS: Seventy six endometrial samples at Korea University Anam Hospital from 1991 to 2001 (37 normal endometrium, 15 endometrial hyperplasia, and 24 endometrial cancer) were immunohistochemically investigated for the expression of variant 6, isoform of CD44. Immunoreactivity scores were generated by multiplication of the values for the immunopositivity and immunointensity. RESULTS: CD44 V6 was detected in 19/37 cases of normal endometrium (only secretory phase), 1/15 endometrial hyperplasia, and 24/24 endometrial cancer. Immunoreactivity was higher in well differentiated endometrial cancer, while no association was noted with cancer stage. CONCLUSION: CD44 V6 expression in normal endometrium is observed in the secretory phase. Detection of expression of CD44 V6 may be useful for the early diagnosis of endometrial cancer and may be an useful prognostic marker.
