Question:

The following are the most frequent sarcomatous elements in bronchial carcinosarcoma except:
1. Osteoid
2. Condroid
3. Rhabdomyoid
4. Lipomatous
5. Lymphangioid





Answer:

The correct answer for the question "The following are the most frequent sarcomatous elements in bronchial carcinosarcoma except:" is:

5. Lymphangioid



Explanation
Lymphangiosarcoma is less frequently described sarcomatous elements in bronchial carcinosarcomas. [Unlike spindle cell carcinoma or homologous sarcomatoid pleomorphic carcinoma whose stromas lack differentiation, mesenchymal components of carcinosarcomas are poorly differentiated, mostly rhabdomyosarcoma, but also osteosarcoma, chondrosarcoma, a combination of these elements, or less frequently liposarcomatous and angiosarcomatous elements.]

Abstract
Carcinosarcoma is an uncommon mixed tumor of the lung. We present the case of a 65 year-old-male with cough and a right lower lobe radio-opacity who underwent resection, showing a large endobronchial tumor with an epithelial component of non-small cell carcinoma and malignant mesenchymal elements. The radiologic and histopathologic features are reviewed with reference to relevant literature.
