Abstract: A patient aged 7 years complained of right-sided nasal premolar maxillary pain and nasal obstruction. He was operated. Post-operative recovery was normal. Histopathological examination revealed tumor tissue. Tumor consisted ofinterlacing bundles of proliferated tumor cells. Tumor cells had elongated nuclei with round ends. IHC showed positive reaction with anti-smooth muscle actin (SMA) antibody, suggesting mesenchymal origin of tumor cells. Tumour cells did not react with anti-S100, anti-synaptophysin and anti-chromogranin antibodies. Thus, the possibility of neural origin of tumor cells was ruled out. The tumor was finally diagnosed as myopericytoma involving right-sided maxillary sinus.
