Tumor phyllodes benigno en el hombre: reporte de un caso y revisión de la literatura / Male benign phyllodes tumor: a case report and review of the literature

Los tumors phyllodes son entidades de origen fibroepitelial en la mama. La incidencia de su presentación es baja, entre 0.5 y 1.0% de todos los tumores mamarios y el 3% de las lesiones fibroepiteliales. Su presetación en hombres es de muy baja frecuencia y se reportaron sólo casos aislados. Se presenta el caso de un paciente de sexo masculino de 53 años que consulta por un nódulo en la mama derecha. Se realizan mamografía y ecografía. Se efectúa resección con estudio intraoperatorio. El informe anatomopatológico fue de tumor phyllodes benigno de 6cm. El caso no presenta antecedentes de importancia (ginecomastia) y su evolución hasta el presente es buena.

[Reproducibility of nuclear grade in breast neoplasm. A multicenter experience]. / Reproducibilidad del grado nuclear en el cáncer de mama. Una experiencia multicéntrica.

Nuclear grade is considered a valuable prognostic factor in mammary carcinomas. Since the histological diagnosis of most of these tumors is made by "non expert" pathologists, it was considered interesting to find out the reproducibility of general pathologists to define the nuclear grade. In order to do this, a series of 15 mammary carcinomas, 10 of them randomly selected and 5 because they were considered difficult to classify for nuclear grade, were examined separately by 10 general pathologists. In a first round of observation, each one of them graded the cases according to their own criteria as used routinely, and for a second round they followed a written guide. An analysis of variance was applied to the data and no significant differences were found between observers, neither in the randomly selected cases nor in the total series. The written guide, surprisingly, instead of lowering the differences, increased them. Analysis of the individual performance of observers showed two of them having a great variation between both rounds of observation, and this was considered to influence the results of the whole group. Interobserver performance to discriminate high grade tumors (G3) from the rest, showed a good correlation in all the participants. These results allow us to conclude that in this series, examined by general pathologists, an acceptable reproducibility was observed, specially when high risk tumors were being identified.

[Contribution on disinfection of dental impressions]. / Ein Beitrag zur Desinfektion zahnärztlicher Abformungen.

The effectiveness of various measures of disinfection with stomatological impressions had microbiologically been tested. The most efficient reduction of the number of germs could be stated after a five minutes influence of 0.5% commercial solution of peracetic acid on calcinate impressions. Gargling by Sol. chlorhexidini SR before taking the impression and a 60 minutes formaldehyde gasification of plaster casts also resulted in an essential reduction of the number of germs, too.
