Myopericytoma is a rare mesenchymal tumor characterized by a hemangiopericytoma-like vascular pattern with perivascular myoid differentiation. To date, only 11 cases of oral myopericytoma have been reported. To the best of our knowledge, myopericytoma with gingival involvement and associated with calcifications has not been reported, expanding their clinicopathological spectrum. Herein, we report a 12-year-old girl female patient who presented a gingival nodule diagnosed as ossifying myopericytoma, which should be considered in the differential diagnosis when assessing oral soft tissue lesions, especially in pediatric patients.
