Summary
Extraskeletal tumors with osteoclast-like giant cells (OGCs) are rare, particularly in the gallbladder. This case highlights a gallbladder adenosquamous carcinoma with OGCs, showing a favorable prognosis and adding to limited research.
Area of Science:
- Oncology
- Pathology
Background:
- Extraskeletal tumors with multinucleated osteoclast-like giant cells (OGCs) are uncommon, predominantly reported in breast and pancreas.
- Some research suggests carcinomas with OGCs may represent a distinct clinicopathological entity with a favorable prognosis.
Observation:
- Gallbladder occurrence of OGC-containing neoplasms is extremely rare, with only one prior documented case.
- A 72-year-old woman presented with gallbladder mass and liver invasion.
- Histological examination revealed adenosquamous carcinoma with benign OGCs.
Findings:
- Immunohistochemical analysis confirmed the giant cells were of histiocytic origin.
- The patient experienced a 6-year survival without evidence of recurrence.
- This case contributes to the limited literature on gallbladder carcinoma with OGCs.
Implications:
- Further research is needed to clarify the prognostic significance of OGCs in gallbladder cancer.
- Distinguishing adenosquamous carcinoma with OGCs from other gallbladder carcinomas with OGCs requires further study.
