A case of monostotic Paget's osteogenic sarcoma initially diagnosed by fine needle aspiration cytology is reported. The value of electron microscopy in this case is emphasized.
Two cases of laryngeal chondrosarcoma are described. The first exhibited a fibrosarcomatous differentiation, which is a rare finding in chondrosarcoma and usually indicates poor prognosis. The second was found in a larynx six years after Teflon injections for the treatment of vocal cord paralysis. The possibility of Teflon as a tumorigenic factor in this case is raised.

An unusual case of asymptomatic squamous cell carcinoma of the esophagus metastatic to the pancreas, mimicking a rare primary pancreatic neoplasm, is reported. Percutaneous fine needle aspiration (FNA) biopsy of a pancreatic lesion showed squamous cell carcinoma, which in the pancreas is virtually always metastatic in origin. This prompted a search for an occult primary elsewhere, resulting in the discovery of an esophageal neoplasm, which in itself is one of the least likely sources of pancreatic metastases. FNA biopsy was thus a useful and accurate diagnostic tool in establishing the true nature of the pancreatic neoplasm, sparing the patient unnecessary pancreatic surgery, with its attendant morbidity and hospital costs.
