a. Fibrosarcoma
b. Malignant fibrous histiocytoma
c. Neurofibroma
d. Ameloblastic fibroma
The correct answer is: B. Malignant fibrous histiocytoma.
MALIGNANT FIBROUS HISTIOCYTOMAS
- are group of aggressive malignant neoplasms, arising from undifferentiated mesenchymal cells that differentiate along both fibroblastic and histiocyte pathways.
- Histologically the neoplasm reveals actively proliferating, numerous polyhedral or oval shaped, malignant histiocytes and many spindle shaped malignant fibrous cells.
- These malignant cells are often arranged in a typical "Cart-wheel" or "Storiform" pattern or Criss cross.
- Fibrous histiocytoma: Storiform pattern (helicopter in wheat field) is seen.
