Malignant epithelial/exocrine tumors of the pancreas

2020

Summary Pancreatic malignant exocrine tumors represent the most important cause of cancer-related death for pancreatic neoplasms. The most common tumor type in this category is represented by pancreatic ductal adenocarcinoma (PDAC), an ill defined, stroma-rich, scirrhous neoplasm with glandular differentiation. Here we present the relevant characteristics of the most important PDAC variants, namely adenosquamous carcinoma, colloid carcinoma, undifferentiated carcinoma, undifferentiated carcinoma with osteoclast-like giant cells, signet ring carcinoma, medullary carcinoma and hepatoid carcinoma. The other categories of malignant exocrine tumors, characterized by fleshy, stroma-poor, circumsc…

Cuantificación de ADN como factor pronóstico en un caso de Carcinoma de células Acinares de parótida diagnosticado por PAAF

2005

Presentamos el caso de un varón de 43 años de edad que consulta por una tumoración preauricular derecha dolorosa a la palpación que, según refiere, tiene más de tres años de evolución. Se realiza punción aspiración con aguja fina que informa de compatible con carcinoma de células acinares, por lo que se realiza cuantificación de ADN por citometría de imagen. Los parámetros biológicos estudiados (ploidía, fase S, células por encima de 5c) indican que se trata de una lesión de bajo grado de malignidad. Con estos datos se practica parotidectomía total conservadora del facial, sin vaciamiento ganglionar. El paciente se encuentra, un año después, asintomático y libre de signos tumorales residual…

Stimulation with carbachol alters endomembrane distribution and plasma membrane expression of intracellular proteins in lacrimal acinar cells.

2000

The events that lead to Sjogren's autoimmune processes in the lacrimal gland remain poorly understood. The acinar cell's responses to acute cholinergic stimulation include release of secretory products across the apical plasma membrane (apm) and a number of processes related to traffic between endomembrane compartments and the basal-lateral plasma membranes (blm), such as recruitment of Na, K-ATPase, accelerated recycling, and accelerated transcytosis of secretory IgA. We tested the hypothesis that stimulation-induced acceleration of endomembrane traffic is accompanied by changes in compartmentation and increased blm expression of proteins that are normally sequestered in endomembrane compa…
