On nasopharyngeal biopsy, epithelioid cells are seen within it, which does not exclude the possibility of malignant disease. Because the mucosa in the nasal cavity should be epithelial cells rather than epithelioid cells, it is recommended to do further pathology as well as immunohistochemical examination to confirm the diagnosis.
Epithelioid cells are not epithelial cells, but are due to the differentiation of other cells into epithelioid-like cells, which are the main cellular component of the body that produces granulomas. Such granulomas are often incompletely cured and are prone to recurrence and metastasis, which can have an impact on the quality of the patient’s survival.
Nasopharyngeal biopsy shows epithelioid cells in the nasopharynx, and it is recommended to do further pathological as well as immunohistochemical examination to exclude the possibility of malignant lesions such as soft tissue sarcoma. Based on the results of further examination, treatment should be carried out under the guidance of the doctor.
