RESUMO
Pheochromocytoma is an uncommon tumor and occurrence of bilateral malignant tumor is extremely rare. Labile hypertension is the common presenting feature of pheochromocytomas. Herein we describe one such case ofbilateral malignant pheochromocytoma, which was clinically silent except for pain and mass in hypochondrium. Histopathology showed features of malignancy along with hyaline globules, which are less described with malignant tumors. Electron microscopy showed neurosecretory granules in tumor cells.

A patient of papillary thyroid carcinoma, who initially presented with a choroidal metastasis and secondary intractable glaucoma is reported. The orange-coloured tumour posed a diagnostic difficulty, until histopathology of the enucleated eye confirmed the metastasis from the thyroid. The initial presentation of distant metastasis in patients with thyroid cancer is rare.
