Abstract

|
|
|
Symptomatic parasellar granular cell tumor is a very rare tumor. To the best of our knowledge, 43 cases was be found in the English literatures. We recently experienced a case of a parasellar granular cell tumor in a 61-year-old female who had bilateral temporal hemianopsia and severe panhypopituitarism. The tumor was composed of diffuse sheets of polygonal cells with abundant eosinophilic PAS positive granular cytoplasm. In the immunohistochemical and ultrastructural examinations, the tumor failed to show any evidence of Schwann cell or glial differentiation. These findings suggest that granular cell tumor has heterogenous cell types of origin.
