20x magnification showing atypical cells with large irregular nuclei.
40x magnification showing large, markedly pleomorphic cells.
40x magnification of malignant cell groups.
60x magnification of malignant cells. Macronucleoli are easily identified.
Resident Questions
Cell Block
40x magnification of cell block of pancreatic mass showing small glands with macronucleoli.
Final Diagnosis
Cytology
- Metastatic prostate carcinoma.
Biopsy Diagnosis
- Conventional high grade sarcoma, sclerotic type.
Discussion
The experience of FNA of osteosarcoma is mainly with conventional high-grade intramedullary sarcoma and to the rare high-grade surface osteosarcoma. Smears usually contain dissociated neoplastic cells and cell clusters.
