Overview
Gallbladder cancer may be classified according to WHO into various subtypes like adenocarcinoma, papillary adenocarcinoma, mucinous adenocarcinoma, signet ring cell carcinoma, adenosquamous carcinoma, squamous cell carcinoma, neuroendocrine carcinoma, small cell carcinoma, undifferentiated carcinoma, spindle cell undifferentiated carcinoma, giant cell undifferentiated carcinoma.
Classification
Gallbladder carcinoma may be classified according to histology into following subtypes.[1]
| SUBTYPE | HISTOLOGICAL FEATURES |
| Adenocarcinoma | Sheets, cohesive fragments, acini, and mucin |
|---|---|
| Papillary adenocarcinoma | Pleomorphism and papillary fragments with vascular core |
| Mucinous adenocarcinoma | Single cells or cluster and extracellular mucin |
| Signet ring cell carcinoma | Intracellular mucin with signet ring cells |
| Adenosquamous carcinoma | Mixture of glandular and squamous components |
| Squamous cell carcinoma | Necrosis, tadpole cells and atypical keratinized cells |
| Neuroendocrine carcinoma | Salt and pepper chromatin,anisonucleosis and rosettes |
| Small cell carcinoma | Absent cytoplasm, Smudge cells, and mitoses |
| Undifferentiated carcinoma | Pleomorphic cells, abundant necrosis |
| Spindle cell undifferentiated carcinoma | Undifferciated type with prominent spindle cells |
| Gaint cell undifferentiated carcinoma | Undifferentiated type with predominant giant cells |
