Pathology of Mucinous Adenocarcinoma of the Gallbladder

Dr Sampurna Roy  MD 

 

Mucinous adenocarcinoma is a type of mucin-producing carcinoma and consists of a massive mucous pool within  the neoplastic tissues.

These tumours consist of more than 50%  extracellular mucin.

There are two histologic variants:

   

Microscopic images of mucinous adenocarcinoma of the gallbladder

a) Contains large pools of extracellular mucin with small clusters of malignant epithelial cells and 

b) those characterized by mucin-filled glands with cystic dilatation.

Foci of both variants may be found admixed with conventional, well-differentiated adenocarcinoma.

The tumour has a poor prognosis because of its tendency toward invasive growth.
