Abstract
Malignant mesenchymal tumors rarely arise in the sellar region. Most of them are either spread of a primary skull base lesion or are secondary to radiation therapy for a pituitary adenoma.
The most common primary sarcoma of the sellar region is the chondrosarcoma, followed by fibrosarcoma and rhabdomyosarcoma, each with a few case reports. Postradiation fibrosarcomas are the most common of these malignant neoplasms.
Pituitary fibrosarcoma is a rare cancer that is often associated with prior radiation exposure or therapy.
Secondary pituitary fibrosarcomas commonly develop 10–15 years after treatment for a separate tumor, often a pituitary adenoma.
