Solitary fibrous tumor (SFT) is a distinct and a rare spindle cell neoplasm, commonly known to occur in the pleura and other serosal sites. With the advent of immunohistochemistry, varied extraserosal sites are being recognized as common locations for this rare tumor. We report a case of SFT in a 50-year-old male patient who presented with multiple swellings in the eyelid, with emphasis on the cytological features.
Pheochromocytoma is a rare tumor, accounting for <0.1% of the hypertensive population. Extra-adrenal pheochromocytomas (EAPs) are rarer still, accounting for 10% of all pheochromocytomas. Pheochromocytomas are functional catecholamine-secreting tumors of the paraganglionic chromaffin cells found in the adrenal medulla and the extra-adrenal paraganglia cells. EAPs are readily detected by computed tomography (CT) as soft tissue masses closely associated with the entire length of the abdominal aorta. Here, we present a rare case of EAP in a 45-year-old male hypertensive patient diagnosed by CT-guided fine needle aspiration cytology. The smears showed loosely cohesive tumor cells with prominent anisokaryosis and abundant eosinophilic, granular cytoplasm. The diagnosis was later confirmed by histopathology. The present case also highlights the fact that fine needle aspiration of pheochromocytoma is not necessarily contraindicated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
