[A case of tonsil sarcomatoid carcinoma]
Summary
Sarcomatoid carcinoma is a rare malignant tumor with both epithelial and mesenchymal cells. This case highlights tonsillar sarcomatoid carcinoma presenting with dysphagia.
Area of Science:
- Oncology
- Pathology
Background:
- Sarcomatoid carcinoma is a rare biphasic malignant neoplasm.
- It exhibits both epithelial and mesenchymal differentiation.
- Simultaneous expression of cytokeratin (CK) and Vimentin is characteristic.
Observation:
- This report details a rare case of sarcomatoid carcinoma originating in the tonsil.
- The initial presenting symptom was dysphagia.
Findings:
- Microscopic examination revealed intermingling of carcinomatous and sarcomatous cells.
- Immunohistochemistry demonstrated simultaneous expression of cytokeratin (CK) and Vimentin, confirming the dual cell lineage.
Implications:
- This case expands the understanding of sarcomatoid carcinoma presentation.
- Early recognition of dysphagia as a symptom is crucial for timely diagnosis of tonsillar malignancies.

9.9K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:03Rous Sarcoma Virus (RSV) and Cancer
6.0K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
