Gallbladder adenocarcinoma differential diagnosis

Squamous cell gallbladder cancer
Squamous cell cancers develop from the skin-like cells that form the lining of the gallbladder, along with the gland cells. Doctors treat these cancers in the same way as adenocarcinomas.

Adenosquamous gallbladder cancer
Adenosquamous carcinomas are cancers that have both squamous cancer cells and glandular cancer cells. Your doctor may call this a 'mixed histology'. Doctors treat these cancers in the same way as adenocarcinomas.

Small cell cancer of the gallbladder
Small cell carcinomas are also called oat cell carcinomas. They are called this because the cancer cells are a distinctive oat shape.

Gallbladder sarcomas
Sarcoma is the name for a cancer that affects the supportive or protecting tissues of the body – also called the connective tissues. Muscles, blood vessels and nerves are all connective tissues. A cancer that begins in the muscle layer of the gallbladder is a sarcoma.
