The human Bartonellosis history Iinked to the exploit of Daniel A. Carrion, a 6th year student of the Faculty of Medicine from UNMSM is analysed on the basis of technological advances and progressive resolutions of different inquiries in the knowledge of the disease.

In Carrion 's disease (human Bartonellosis ) described two phases: 1 ) Phase blood count and 2 ) Phase histíoide . In Phase hematic recently been shown that the Bartonella bacilliformis etiolóqico Disease agent is located within the host erythrocyte . 1) pre - eruptive period and 2 ) Eruptive Period or verrucous outbreak : In Phase histioide two periods described . The histological picture of verrucous button is a capillary hemangioma granuloma or a pióqeno : however, sometimes the differential diagnosis with other entities , especially malignancies, is difficult. Special staining techniques , it has been observed in the cytoplasm of cells verrucoma histioides small granules have been considered baciliformis form . In this paper discloses the results of the ultrastructural study of Bartonella - complex and RBC verrucoma for which thin sections were used coagulated blood, desfibringda ...

The development of fixation techniques, embedding and sectioning of tissues for electronic microscopy made it possible, since the early 60s, valuable information on endometrial ultrastructure of various animal species and women to accumulate in normal and hormone activity. Anchor works and collaborators, Nilsson, of Clyman, Tarzakis and Cavazos et al highlight what limited as far as ultrastructural details of the endometrium of women during the normal menstrual cycle is concerned.

Endometriosis occurs with many morphological patterns because, unlike adenomyosis, almost invariably suffer influence ovarian hormonal changes. In the ovary is presented as small cortical nodulitos reddish dark blue, particularly at the free edge and the side surfaces, remembering foci of fibrin deposits.

Dr. Javier Arias-Stella distinguished peruvian pathologist is knowed in the field because achievement of his discovery which has his name: “Arias-Stella-Reaction”. This discovery which was started at Pathology Institute ahead by Profesor Pedro Weiss Harvey in San Marcos University, was the beginning along his life which is giving in his contribution of knowledge of gynecologic pathology, pulmonary-cardiovascular anatomy and pathology of people living at high altitude at the Peruvian Andes mountain- and other topics of pathology. In tandem of is research advanced, his teacher activities taking place at UNMSM and UPCH which can be expressed thought his disciples who practice medicine at hospitals in Peru and other countries. Dr. Arias-Stella also had active participation in politic life of Perú.

The morphological characteristics of atypical epithelial disruption occurs in the seminal vesicle are described. The lesion is mainly characterized by focal areas in which there is marked nuclear hypertrophy and some degree of epithelial hyperplasia. The exioliadas hypertrophic cells can be confused with neoplastic cells. The alteration occurs mostly after the fourth decade. Inflammation and vascular sclerosis in the seminal vesicle, prostate gland hyperplasia, abnormality or atrophy of the testes, or pathological processes in each case apparently unrelated to the presence of the disturbance.

INTRODUCCIÓN: La colonoscopía con imagen de banda angosta (NBI) y Magnificación Óptica es un método útil para evaluar in vivo el patrón Capilar y el Patrón de las criptas de los pólipos colorrectales. OBJETIVO: Evaluar la utilidad del NBI y magnificación óptica en el diagnóstico diferencial de los pólipos colorrectales empleando las clasificaciones de Sano-Emura y Kudo. MÉTODOS: 86 colonoscopías de enero - mayo 2010, encontrándose 136 pólipos, analizados histológicamente, incluyéndose en el estudio: 119 (≤ 10mm), siendo evaluados de acuerdo a las Clasificaciones de Sano-Emura y Kudo, los datos fueron analizados en conjunto con un epidemiólogo en cáncer. RESULTADOS: La sensibilidad, especificidad y precisión diagnóstica para la clasificación de Sano-Emura fue 97.3% , 90.7% y 94.9% respectivamente. La sensibilidad, especificidad y precisión diagnóstica para la c...
