Synchronous Thyroid Involvement in Plasma Cell Leukemia Masquerading as Hashimoto's Thyroiditis: Role of Ancillary Cytology Techniques in Diagnostic Workup.

abstract：:Pheochromocytomas and paragangliomas are neuroendocrine neoplasias of neural crest origin. Genetic mutations that are characterized in other human neoplasms are rarely seen in these tumors. About 10% of the patients with pheochromocytomas and paragangliomas present with a family history of von Hippel-Lindau disease (V...
