Hemangiopericytoma- A solitary tongue lesion

Hemangiopericytoma (HPC) is a mesenchymal tumour that is usually benign, but has definite malignant counterpart. 16-25 % cases of all reported HPC's are observed involving Head and Neck region. We report a case of HPC on the left lateral border of tongue. The histopathology features revealed increased cellularity, vascularity with some staghorn pattern. Observed nuclear pleomorphism and vesicular as well as hyperchromatic nuclei suggest an intermediate grade characterized by unpredictable clinical behaviour. Therefore long follow up is essential. No local recurrence or distant metastasis was noticed in a 5 year follow-up period.
