Ossifying spindled and epithelioid tumour: Expanding the clinical and morphologic spectrum of a recently described entity
Our cohort expands the clinical and morphologic spectrum of this entity to include tumours with increased mitotic activity and necrosis, as well as highlights the first two examples of non-ossifying OSET. Moreover, while confirming the overall indolent behaviour of OSET, we described cases that demonstrate primary multifocal disease and local recurrence.
