A 42-year-old woman presented with diplopia and headache of 3 months duration. She was found to have ptosis and decreased visual acuity of right eye. Computed tomography (CT) scan and magnetic resonance imaging (MRI) showed a 2.8 cm-sized sellar lesion with areas of mineralization [Figure 1]. Endocrine evaluation was normal. Surgical debulking of the tumor was done through frontotemporal craniotomy. The tumor was seen involving the sphenoidal sinus, sphenoid bone, and clivus. Histological evaluation revealed a malignant tumor composed of irregular oval to pleomorphic cells of epithelioid morphology admixed with elongated ovoid tumor cells arranged in sheets and f ocally lining the slit-like vascular spaces with a variably hyalinized myxochondromatous stroma in the background [Figure 2]. The tumor cells showed eosinophilic cytoplasm with cytoplasmic vacuoles containing an occasional erythrocyte in few cells [Figure 2d]. Scattered foci of metaplastic calcification were seen. Mitotic activity was very occasional and no necrosis seen.
