Conclusion

We present our institutional series of 4 GCT, 4 PCT, and 3 SCO tumor patients, the largest to date of these three TTF-1 staining tumors of the sellar region. GCTs were reliably found to be exclusively suprasellar at presentation. SCOs tended to present with more endocrine abnormalities, but less likely to have endocrine worsening postoperatively. Gross total resection was achieved in all cases with no known recurrence at nearly 5 years of mean follow up.

Abbreviations

GCT - granular cell tumor, PCT - pituicytoma, SCO - spindle cell oncocytoma, TTF - thyroid transcription factor,  MRI - magnetic resonance imaging
