Why the study?
Alveolar soft part sarcoma commonly involves the extremities and head and neck regions, whereas primary intracranial presentations are rare.
Histopathology with immunohistochemistry is diagnostic for rare primary intracranial alveolar soft part sarcomas, which are often not suspected clinically.
Emphasizes tissue diagnosis for clinically unsuspected intracranial sarcomas; leaves open the broader epidemiological and prognostic.
Alveolar soft part sarcoma (ASPS) commonly involves extremities and head and neck regions. Primary intracranial ASPS is rare. We report a series of 3 primary intracranial ASPS. These were not suspected clinically and histopathology with immunohistochemistry proved to be diagnostic in all 3 tumors.
