RESUMO

RESUMEN La inmunohistoquímica permite clasificar al cáncer de mama en subtipos que tienen relevancia para el tratamiento y pronóstico. En comparación con los marcadores genéticos, la inmunohistoquímica es de costos accesibles, más fácil de realizar y tiene buena correlación con los subtipos moleculares. Objetivo: Describir el perfil inmunohistoquímico de cáncer de mama en pacientes atendidos en un hospital general de Lima, Perú. Material y métodos: Estudio descriptivo, transversal y retrospectivo que incluyó todos los casos de carcinoma invasivo de mama diagnosticados entre el 1 de mayo de 2015 y el 30 de abril del 2017. Se realizó la descripción histopatológica de los casos y se los clasificó de acuerdo con los protocolos actuales en cuatro subtipos. Resultados: Se reportaron 330 casos de cáncer de mama, 71 fueron excluidos, quedando 259 para el estudio. La media de edad fue de 54,64 ± 14,07. La neoplasia se localizó de la mama derecha en la mitad de casos. El 88,03% correspondió al tipo histológico carcinoma invasivo ductal no especial, y el grado histológico fue intermedio en el 53,28% de los casos. El subtipo molecular fue Luminal A en el 40,15% del total, y solo un 11,97% de las muestras fueron HER2/neu positivo no luminal. Conclusiones: Uno de cada cuatro casos de cancer de mama presentó una inmunohistoquímica de Her2/neu positivo, mientras que el subtipo inmunohistoquímico más común de carcinoma de mama invasivo fue Luminal A. De igual forma, el grado histológico se asocia al subtipo inmunohistoquímico.


SUMMARY Immunohistochemistry (IH) allows to classify breast cancer in subtypes that are relevant for treatment and prognosis. Compared to genetic markers, IH is cheaper, easier to perform and has good correlation with molecular subtypes. Objective: To describe the immune phenotypic profile of patients with breast cancer attended at a public hospital in Lima, Peru. Methods: Cross-sectional study that included all cases of invasive breast cancer diagnosed from May 1st 2015 to April 30, 2017. Histopathological description was performed and cases were classified based on current protocols into four subtypes. Results: 330 cases were included; 71 were excluded; 259 were left for analysis. Mean age was 54.64 ± 14.07 years. In half of cases the cancer was located in the right breast. The invasive ductal carcinoma accounted for 88.03% of cases; the intermediate histological degree was found in 53.28% of cases. The molecular subtype Luminal A accounted for 40.15% and only 11.97% were non-luminal HER2/neu positive. Conclusions: One in four cases of breast cancer presented with the IH pattern of HER2/neu positive, while the most common IH subtype was Luminal A. Histological degree was associated with the IH subtype.

RESUMO

OBJECTIVES: Describe the clinical and biochemical characteristics of patients with histopathological findings compatible with steatohepatitis of HNAL patients between 2010-2012. Determine the frequency of alcoholic and non-alcoholic steatohepatitis, presence of metabolic syndrome and other factors associated to non-alcoholic steatohepatitis, its main indications for liver biopsy and biochemical characteristics according to the severity of the histological findings. MATERIALS AND METHODS: We evaluated all histological slides of liver biopsies of the period between 2010-2012, of which, those with the diagnosis of steatohepatitis were selected. Their medical records were then reviewed. RESULTS: 32 patients met inclusion criteria. 28 were female and 4 male, the average age was 49±12 years. Two patients had a history of chronic alcohol consumption, representing the group of alcoholic steatohepatitis. The more frequent clinical finding in patients with NASH (non-alcoholic steatohepatitis), was obesity (37%). 50% of patients had AST/ALT ratio <1. CONCLUSIONS: Among population studied, non-alcoholic steatohepatitis was more common than alcoholic steatohepatitis, being obesity the most associated factor.

RESUMO

Describir las características clínicas y bioquímicas en pacientes con histología compatible con esteatohepatitis del Hospital Nacional Arzobispo Loayza en el periodo 2010-2012. La frecuencia de esteatohepatitis alcohólica y no alcohólica, la presencia de síndrome metabólico y otros factores asociados a esteatohepatitis no alcohólica, sus principales indicaciones de biopsia hepática, y las características bioquímicas de acuerdo a la severidad del cuadro histológico. Materiales y métodos: Se evaluaron todas las biopsias hepáticas del período 2010-2012, se seleccionaron las muestras con diagnóstico de esteatohepatitis. Luego se revisaron sus respectivas historias clínicas. Resultados: 32 pacientes con esteatohepatitis cumplieron los criterios de inclusión, 28 fueron de sexo femenino y 4 masculino, cuya edad fue 49+/-12 años, 30 (94%) presentaba esteatohepatitis no alcohólica. Dos pacientes presentaban el antecedente de consumo crónico de alcohol, representando al grupo de esteatohepatitis alcohólica. La característica clínica más frecuente en pacientes con esteatohepatitis no alcohólica, fue obesidad en 11 (37%) pacientes. La relación de AST/ALT <1 estuvo presente en 15 (50%) pacientes. Conclusiones. En esta población la esteatohepatitis no alcohólica es mucho más frecuente que la alcohólica y la obesidad estuvo más relacionada con la presencia de esteatohepatitis no alcohólica...

RESUMO

Benign recurrent intrahepatic cholestasis (BRIC) is a rare form of intrahepatic cholestasis characterized by repeated self-limited episodes of severe pruritus and jaundice. Classically its natural evolution is benign, without progress to fibrosis or hepatic insufficiency; although, lastly were reported cases which progress to Progressive familial intrahepatic cholestasis (PFIC). This disease is characterized by progressive hepatic insufficiency and cirrhosis. We present the case of a 32 years old male patient who went to Gastroenterology Service of Arzobispo Loayza National Hospital by pruritus and jaundice. We reported this case for its infrequent presentation and because is an entity which should be considered within differential diagnosis of hepatic cholestasis diseases.

RESUMO

La Colestasis Intrahepatica Benigna Recurrente (CIBR) es una rara forma de colestasis intrahepatica caracterizada por episodios recurrentes y autolimitados de ictericia y prurito intensos. Clásicamente su evolución natural es benigna, sin progresión a fibrosis o insuficiencia hepática; sin embargo, últimamente se han reportado casos que progresan a Colestasis Intrahepatica Familiar Progresiva (CIFP), ésta última caracterizada porinsuficiencia hepática y cirrosis. Presentamos el caso de un paciente varón de 32 años que acude al Servicio de Gastroenterología del Hospital Nacional "Arzobispo Loayza",por ictericia y prurito. Lo reportamos por lo infrecuente de su presentación y por ser una entidad que debemos tener en cuenta en el diagnóstico diferencial de enfermedades hepáticas colestásicas.

RESUMO

La Dermatomiositis amiopática es una variante de dermatomiositis en la cual los pacientes tienen manifestaciones cutáneas sin evidencia clínica de afectación muscular y en los que las pruebas complementarias no demuestran ningún grado de inflamación muscular durante más de 2 años. Se presenta un paciente varón de 47 años de edad que acude al consultorio de dermatología con lesiones eritematosas en cara, brazos, pecho y espalda, levemente pruriginosas, no dolorosas, fotosensibilidad, cambios en la piel de articulaciones de las manos y codos, acompañados de caída de cabello de mas de dos años de evolución sin compromiso neurológico motor. Los exámenes de laboratorio confirman el diagnóstico de dermatomiositis amiopática.


Amyopathic dermatomyositis is a variant of dermatomyositis in which the patients have cutaneous manifestations without clinical evidence of muscular affectation and in that the complementary tests donÆt demonstrate any degree of muscular inflammation during more than 2 years. A 47-year old patient male is described, who had erithematous lesions in face, arms, chest and back, slightly pruritic, painless, with photosensibility, changes in the skin of joints of the hands and elbows, accompanied of alopecia of more than two years of evolution without neurological motor commitment. The laboratory examinations confirm the diagnosis of amyopathic dermatomyositis.

RESUMO

La poroqueratosis actínica superficial diseminada (PASD) es una enfermedad hereditaria con queratinización defectuosa. Las lesiones aparecen de forma simétrica en áreas fotoexpuestas y morfológicamente se presentan pápulas y lesiones anulares hiperqueratósicas de centro atrófico y borde elevado. Presentamos el caso de una paciente con esta entidad, con lesiones de localización inusual en frente y pirámide nasal y sin historia familiar de la enfermedad.
