We describe a case of a rare soft-palatal and parapharyngeal mass in an adult woman. A 71-year-old female presented with a huge mass protruding from the soft palate, complaining about difficulty in swallowing for the past 4 months. After inspection and ear nose and throat fibroscopy, in which the mass appeared regular-shaped and with a regular mucosa, the patient underwent a CT scan and MRI examination. The CT scan showed an oval, not-infiltrating, hypodense mass including a discrete irregular-shaped central calcification, while the MRI examination confirmed the non-infiltrating growth and showed that around the calcified core, the lesion was surrounded by fat. After surgical removal, the histopathologic diagnosis was that of an "ectomesenchymal chondromyxoid tumour". Ectomesenchymal chondromyxoid tumour is a rare benign neoplasm arising from the tongue. Although only 45 cases have been reported in the literature, there are several unique features that define this lesion. Ours is the first case with a complete CT scan and MRI with diffusion imaging description.
