RéSUMé
La muqueuse de l’endobrachyœsophage est caractérisée par un large éventail d’aspects histopathologiques, soit chez un même patient, soit chez des patients différents. Ces variations conduisent à une mosaïque de types de muqueuses ou de cellules métaplasiques.
En plus de cette mosaïque histopathologique, on observe fréquemment une architecture désorganisée caractérisée par une surface irrégulière et une distribution irrégulière des glandes et des cryptes. En outre, le diagnostic dépend également du site anatomique où le prélèvement d’épithélium cylindrique a été effectué. Pour cette raison, une collaboration étroite s’impose entre le pathologiste et le gastroentérologue.
Summary
Barrett’s columnar mucosa is characterized by a wide variation in histopathologic appearance either in one patient or among different patients. This variation leeds to a mosaic of mucosal and cellular types with metaplaslic features. In addition to the mosaic pattern, a disordered architecture characterized by an irregular surface and the irregular distribution of glands and pits is also common. The diagnosis however depends also on the anatomic site from which the columnar-lined specimen was obtained. Therefore a close collaboration between the pathologist and the gastroenterologist is needed.
