Colangiocarcinoma tubulopapilar, una entidad emergente poco frecuente, a propósito de un caso

Objetivo: realizar una revisión bibliográfica y presentación de caso de colangiocarcinoma tubulopapilar. Material y Método: Se revisó la ficha médica y las características clínicas, radiológicas y patológicas del tumor, y la literatura científica respecto al carcinoma tubulopapilar. Caso Clínico: Paciente con ictericia progresiva asociado a baja de peso. El estudio imagenológico muestra amputación del tercio distal del colédoco por tejido de partes blandas, sugerente de colangiocarcinoma. Se realiza endosonografía, arrojando "fragmentos superficiales de adenocarcinoma tubulopapilar". Se realiza duodenopancreatectomía cefálica y, posteriormente, se inicia quimioterapia. Discusión: El colangiocarcinoma es una neoplasia de la vía biliar. Existen diferentes variantes histológicas, entre ellas el colangiocarcinoma tubulopapilar. Su diagnóstico se basa en estudios imagenológicos y anatomopatológicos. El principal hallazgo imagenológico va a depender del patrón de crecimiento tumoral; masiforme, periductal o intraductal. Dentro de los intraductales, se describe un carcinoma biliar con crecimiento tubulopapilar, con fenotipo pancreatobiliar epitelial. En los últimos años han sido de interés por tener mejor pronóstico. Conclusión: El colangiocarcinoma tubulopapilar es una variante histológica poco frecuente del colangiocarcinoma, que se asocia a un mejor pronóstico que otras variantes.

Objective: To conduct a literature review and present a case study of tubulopapillary cholangiocarcinoma. Material and Method: The clinical record and the clinical, radiological, and pathological characteristics of the tumor were reviewed, along with the scientific literature regarding tubulopapillary carcinoma. Case Report: Patient with progressive jaundice associated with weight loss. Imaging studies show amputation of the distal third of the common bile duct by soft tissue, suggestive of cholangiocarcinoma. Endosonography was performed, yielding "superficial fragments of tubulopapillary adenocarcinoma." Subsequently, a cephalic duodenopancreatectomy is performed, followed by chemotherapy. Discussion: Cholangiocarcinoma is a neoplasm of the biliary tract. There are different histological variants, including tubulopapillary cholangiocarcinoma. Its diagnosis is based on imaging and pathological studies. The main imaging finding will depend on the pattern of tumor growth: mass-forming, periductal, or intraductal. Among the intraductal types, a biliary carcinoma with tubulopapillary growth and an epithelial pancreatobiliary phenotype has been described. In recent years, they have been of interest due to their better prognosis. Conclusion: Tubulopapillary cholangiocarcinoma is a rare histological variant of cholangiocarcinoma that is associated with a better prognosis than other variants.

Angiomiolipoma hepático epitelioide: reporte de un caso / Hepatic epithelioid angiomyolipoma: Case Report

Angiomyolipomas (AML) are mesenchymal tumors belonging to the group of perivascular epithelioid cell tumors, which, rarely, can display a malignant behavior. They are composed of adipose tissue, vessels, and muscle tissue in different proportions, and constitute a differential diagnosis for other focal liver lesions. We report a 34-year-old woman in whom a focal hepatic lesion was discovered incidentally. The pathology report of an ultrasound guided biopsy informed an epithelioid angiomyolipoma, a rare variant of these lesions. During ten years of imaging follow, the size and features of the lesion has not changed. The patient rejected a surgical excision.

Rol de las imágenes en la patología arterial no ateroesclerótica poco frecuente en el abdomen / Role of images in rare vascular pathology in the abdomen

Resumen La patología arterial no ateromatosa constituye un grupo de patologías poco frecuentes, pero de gran importancia debido a su morbilidad y mortalidad asociadas. La presentación clínica de estas entidades es inespecífica, por lo que el estudio inicial con imágenes es fundamental. Debido a esto, es muy importante reconocer los signos radiológicos característicos de cada una en las diversas modalidades imagenológicas para poder sospechar y orientar el diagnóstico.

Abstract Non-atheromatous arterial pathology constitutes a group of infrequent pathologies but of great importance due to their associated morbidity and mortality. In general, the clinical presentation of these pathologies is quite nonspecific, so the clinician decides to perform imaging studies thinking of more common entities. It is for this reason that it is very important to recognize characteristic radiological signs in the various imaging modalities to be able to suspect and orient a pathology of this kind.

Tumor desmoide abdominal gigante en puerperio: caso clínico y revisión de la literatura / Giant abdominal desmoid tumor during the puerperium: Case report and review of literature

Introducción. Los tumores desmoides o fibromatosis agresiva corresponden a neoplasias mesenquimales poco frecuentes. Son tumores localmente agresivos que ocurren especialmente en jóvenes, no desarrollan metástasis a distancia, pero se asocian con invasión locorregional y alta tasa de recurrencia después de la resección. Su etiología es desconocida, pero se ha asociado al síndrome de Gardner, trauma, embarazo, estados hiperestrogénicos y puerperio. El objetivo de este artículo fue hacer una revisión sobre el tema a propósito de un caso clínico. Caso clínico. Se presenta el caso de una paciente puérpera con progresivo y rápido aumento del volumen abdominal. Se realizó una tomografía computarizada de abdomen y pelvis que confirmó la presencia de una masa intraperitoneal bien definida. La paciente fue operada con escisión de la masa y confirmación histológica de tumor desmoide a partir de la muestra de patología. Discusión. Los tumores desmoides tienen una incidencia de 2 a 4 casos por millón de habitantes por año, con leve predominio en el sexo femenino y representan menos del 3 % de los tumores de partes blandas. Aunque el tumor se puede ubicar a nivel intraabdominal o en la pared, la ubicación más común es en las extremidades. Conclusiones. La sospecha y detección del tumor desmoide es fundamental, así como su adecuado estudio, para determinar el tratamiento quirúrgico como fue realizado en este caso

Introduction. Desmoid tumors or aggressive fibromatosis correspond to rare mesenchymal neoplasms. They are locally aggressive tumors that occur especially in young people, they do not develop distant metastases, but are associated with locoregional invasion and a high recurrence rate after resection. Its etiology is unknown, but it has been associated with Gardner syndrome, trauma, pregnancy, hyperestrogenic states, and puerperium. The objective of this article was to review the topic based on a clinical case. Clinical case. The case of a puerperal patient with progressive and rapid increase in abdominal volume is presented. An abdominal and pelvic CT scan was performed, which confirmed the presence of a well-defined intraperitoneal mass. The patient underwent surgery with excision of the mass and histological confirmation of a desmoid tumor from the pathology sample. Discussion. Desmoid tumors have an incidence of 2 to 4 cases per million inhabitants per year, with a slight predominance in females, and represent less than 3% of soft tissue tumors. Although the tumor can be located intra-abdominal or in the wall, the most common location is in the extremities. Conclusions. The suspicion and detection of the desmoid tumor is essential, as well as its adequate study to determine the surgical treatment as it was done in this case

Hematocele y hemoperitoneo como manifestación inicial de carcinoma hepatocelular: caso clínico / Hematocele and hemoperitoneum as initial manifestation of hepatocellular carcinoma: report of one case

Hepatocellular carcinoma (HCC) rupture is a rare complication, with a higher prevalence in countries of Asia and Europe. Its clinical manifestations can be nonspecific, from abdominal pain and bloating to hemodynamic involvement. We report a 70-year-old male patient with a history of chronic liver disease, presenting with an enlargement and ecchymosis of the scrotum, associated with abdominal bloating. The initial abdominal ultrasound study showed increased liquid content in the scrotal sac and regional edema. A CT of the abdomen and pelvis showed a liver mass with characteristics of hepatocellular carcinoma, associated with extensive hemoperitoneum that drained into the scrotal sac. The patient was treated with embolization of the right hepatic artery and later with surgical resection of the tumor mass, with a good clinical evolution.
