Metastases to the sellar region and pituitary gland are rare and usually occur in advanced cancers, commonly breast and lung adenocarcinomas. Metastases from sarcomas to the pituitary gland are extremely rare. Here, we report the case of a 52-year-old man who had undergone surgery and radiotherapy for a clear cell sarcoma (CCS) of the knee at age of 42. The patient underwent resection of 2 distinct metastatic lung nodules 9 years later. During follow-up, he developed a persistent headache and diabetes insipidus. MRI revealed a sellar and suprasellar lesion, which was removed with an endoscopic trans-sphenoidal approach. Histopathology was consistent with CSS metastasis. At 2-year follow-up, there was no evidence of local recurrence in the sella, while a single brain metastasis was documented, together with other deposits in the paravertebral and pelvic muscles. CCS is a rare, aggressive neoplasm usually involving the deep soft tissue of the extremities, including trunk or limb girdles, and extensive surgical removal, along with adjuvant chemo- and radiotherapy, significantly prolongs survival. Nevertheless, prognosis remains poor, mainly due to frequent local recurrences and eventually distant metastases, usually within regional lymph nodes, lung, and bone. To the best of our knowledge, this is the first description of a sellar metastasis from CCS.

Abstract

Metastases to the sellar region and pituitary gland are rare and usually occur in advanced cancers, commonly breast and lung adenocarcinomas. Metastases from sarcomas to the pituitary gland are extremely rare. Here, we report the case of a 52-year-old man who had undergone surgery and radiotherapy for a clear cell sarcoma (CCS) of the knee at age of 42. The patient underwent resection of 2 distinct metastatic lung nodules 9 years later. During follow-up, he developed a persistent headache and diabetes insipidus. MRI revealed a sellar and suprasellar lesion, which was removed with an endoscopic trans-sphenoidal approach. Histopathology was consistent with CSS metastasis. At 2-year follow-up, there was no evidence of local recurrence in the sella, while a single brain metastasis was documented, together with other deposits in the paravertebral and pelvic muscles. CCS is a rare, aggressive neoplasm usually involving the deep soft tissue of the extremities, including trunk or limb girdles, and extensive surgical removal, along with adjuvant chemo- and radiotherapy, significantly prolongs survival. Nevertheless, prognosis remains poor, mainly due to frequent local recurrences and eventually distant metastases, usually within regional lymph nodes, lung, and bone. To the best of our knowledge, this is the first description of a sellar metastasis from CCS.
