Pathology of Undifferentiated Carcinoma of the Gallbladder

Dr Sampurna Roy MD  

 

Undifferentiated carcinoma has four histologic variants, including spindle and giant cell type, osteoclast-like giant cell type, small cell type, and nodular or lobular type.

The most common and most anaplastic variant is spindle and giant cell type, which has been referred to as sarcomatoid carcinoma.

Undifferentiated carcinoma of the gallbladder tends to form a large mass with central necrosis and exhibits rapid growth with direct invasion into an adjacent organ.

The tumour is highly aggressive and shows progression to lymph node metastasis and peritoneal dissemination.

The prognosis is very poor.

The tumour is often localized to the fundus of the gallbladder.

In some cases no tumour recurrence was evident at the 6 month follow-up.
