Metastatic Renal Cell Carcinoma Masquerading As Benign Cystic Lesion on Cytology

ABSTRACT

Clear Cell-Renal Cell Carcinoma (CC-RCC), the mostcommon subtype, accounting for 75% of all RCCs, canmetastasize to any part of the body. Nodal metastasis iscommonly noted in the pulmonary, tracheal andretroperitoneal lymph nodes. However, metastasis tocervical/supraclavicular lymph nodes is extremelyrare. Moreover, these metastatic nodal deposits areusually solid, but may become cystic, which warrants adifferential diagnosis of metastatic lesion in an elderlypatient. So, here we report a case of metastatic RCCpresenting as left supraclavicular lymphadenopathywithout any clinical manifestations of the primarywhich was misdiagnosed as a benign cystic lesion oncytology.
