Cervical Nodal Metastatic Pituitary Carcinoma: A Case Report

Pituitary carcinomas are rare tumors with only 170 cases reported in the literature.¹ They form a very small proportion of pituitary tumors, which are commonly benign adenomas. Metastatic disease diagnosed by fine needle aspiration cytology is extremely rare and has only been reported in 6 patients,^2-5 3 of whom had cervical nodal metastases, with other sites of metastases being the liver and cervical vertebra. We report a case of cervical metastatic pituitary carcinoma diagnosed by core needle biopsy.
