“…The transfer matrix method is an efficient approach in light or charged particle optics for studying geometrical properties of any optical system (Pérez 2004, Hecht 2005, Halbach 1964, Gerrach and Burch 1975, Wollnik 1987. In light optics, under the Gauss approximation, Snell-Descartes' laws are linear, so that any optical centred system can be characterized by an abcd-matrix.…”

“…The respective positions z o = EA o and z i = SA i on the optical axes of a given transverse object A o B o and its image A i B i given by the system are also given using [T ] ES through the abcd-rule, or homographic one (Pérez 2004),…”

“…However, from a pedagogical viewpoint, the matrix method is not often encountered in undergraduate books. In geometrical optics and classical electronics, surprisingly, only a few recent books devote a sufficient place to the transfer matrix approach (Pérez 2004, Hecht 2005, Pérez et al 2006, although this has been well known in light optics for about 40 years (Halbach 1964, Gerrach andBurch 1975); the same matter of art states in charged particle optics (Cotte 1938, Lannes and Pérez 1983, Wollnik 1987, Pérez and Lannes 1989. For quantum physics, the transfer matrix method is found in some undergraduate books (Kroemer 1994, Singh 1996, Ferry 2001, Levi 2003.…”

The aim of this paper is to propose a synthetic approach to the transfer matrix method in classical and quantum physics. This method is an efficient tool to deal with complicated physical systems of practical importance in geometrical light or charged particle optics, classical electronics, mechanics, electromagnetics and quantum physics. Teaching would benefit by using the abcd-matrix which in addition is easy to implement on a personal computer.

“…Las principales manifestaciones del carcinoma es la presencia de secreción clara o sanguino lenta por el pezón y la existencia de una masa que se encuentran en lesiones periféricas en forma de microcalcificaciones [3]. Este tipo de carcinoma se manifiesta de forma frecuente en la edad adulta [4]. El carcinoma papilar sólido de mama, una entidad recientemente definida, es poco reconocido, y su naturaleza y manejo aún se debaten [5,6].…”

Intraductal papillary carcinoma, also known as papillary ductal carcinoma in situ, forms part of a heterogeneous group of breast lesions, the reported incidence rates are very low and occurs in 27.7/100,000 in women, although the percentage of mortality is only 1%. This carcinoma is characterized because it can affect the inside portion of the mammary ducts, respecting the basement membrane, with proliferation of neoplasic cells, and since it is not in contact with the lymphatic vessels the possibility of metastasis is almost null. However, the risk of progressing to invasive cancer is nevertheless multifactorial as well as its size, histology, and resection margin. Clinically, it can be characterized by the presence of a single or multiple mass of moderate size, and on a mammograph it’s seen as nodular lesions with irregular edges. The case of an older adult female patient with a mammary nodule with 5 months of evolution, until it forms into a mass and later the execution of routine and laboratory examinations, allowing the diagnosis of intraductal papillary carcinoma to be confirmed. Due to the complexity of the clinical presentation and the age of the patient, a radical mastectomy and physiotherapy of the right upper limb was performed. intraductal papillary carcinoma represents less than 1% of all mammary carcinomas, and has a good prognosis. Keywords: carcinoma, mom, papillary. RESUMEN El carcinoma papilar intraductal, también conocido como carcinoma ductal in situ papilar, forma parte de un grupo heterogéneo de lesiones de la mama, la tasa de incidencia es muy baja y se presenta en 27,7/100.000 en mujeres, aunque el porcentaje de mortalidad es de tan solo el 1%. Se caracteriza porque en el interior de los ductos mamarios y respetando la membrana basal hay proliferación de células neoplasias, y al no encontrarse en contacto con los vasos linfáticos la posibilidad de metástasis es casi nula, más sin embargo el riesgo de progresar a cáncer invasor es multifactorial como su tamaño su histología y el margen de resección. Clínicamente se caracteriza por ser masas únicas o múltiples de tamaño moderado y en la mamografía se observan como lesiones nodulares de bordes irregulares. Se presenta el caso de una paciente adulta mayor que presenta un nódulo mamario de 5 meses de evolución, hasta tornarse en una masa y posterior a la ejecución de exámenes de gabinete y de laboratorio se confirma el diagnóstico de carcinoma papilar intraductal, por la complejidad del cuadro y por la edad de la paciente, se realiza como tratamiento mastectomía radical y fisioterapia del miembro superior derecho. El carcinoma papilar intraductal representa menos del 1% de todos los carcinomas mamarios, y es de buen pronóstico. Palabras claves: carcinoma, mama, papilar.

“…Papillary carcinomas can be divided into invasive and noninvasive forms; the latter forms are in turn subdivided into localized (intracystic papillary carcinoma) and diffuse forms considered to be a variety of ductile carcinoma in situ 1 . Intracystic papillary carcinoma is characterized by papillary growth within a cyst and may be associated with ductile carcinoma in situ (46%) or with an infiltrating carcinoma (36%) 2 . The absence of myoepithelial cells in the periphery of the areas of the papillary tumor has been histologically used to define the invasive nature of the injury 3 .…”

Intracystic papillary carcinoma of the breast associated with areas of infiltration, is a rare, constituting less than 1% of breast cancers. These are tumors whose initial radiological study shows lesions with low suspicion of malignancy in a high proportion of cases. We present two cases of intracystic papillary carcinoma, associated with infiltration diagnosed at the Breast Unit of Hospital Infanta Cristina In both cases the reason for consultation was the palpation of a nodule and initial radiographic approach showed lesions with low suspicion of malignancy
