Diagnostic challenges and morphological profile of gallbladder carcinoma

Ajouté : 2026-05-18

[00:00:01][music] >> Gallbladder carcinoma is a rare but highly aggressive malignant neoplasm, often detected at advanced stages due to the non-specific nature of its initial clinical manifestations.

[00:00:16]Its development is closely associated [music] with chronic inflammatory processes, especially cholelithiasis and persistent [music] cholecystitis, which create an environment of continuous epithelial damage and promote the metaplasia-dysplasia-carcinoma [music] sequence.

[00:00:36]Anatomical factors and predisposing conditions, such as pancreatobiliary [music] junction abnormalities or large gallbladder polyps, can also increase [music] the risk of malignant transformation.

[00:00:50]From a histopathological perspective, adenocarcinoma is the most common subtype, exhibiting infiltrative glandular patterns with varying degrees of differentiation and frequent early invasion of the gallbladder wall and adjacent hepatic structures.

[00:01:09]Microscopic [music] evaluation should assess the depth of invasion, vascular and perineural involvement, and surgical margins, all essential elements for accurate staging.

[00:01:22]In the field of immunohistochemistry, the expression of epithelial markers and the identification of specific molecular alterations contribute to the differential diagnosis of metastases and the biological characterization of the tumor.

[00:01:39]Finally, the integration of morphological, clinical, and tumor extent findings is essential for establishing the prognosis and guiding the therapeutic strategy in this highly complex oncological entity.
