Cervical lymph nodes metastases from a pituitary carcinoma.
The authors report a case of a pituitary carcinoma which was locally invasive and which metastasized to cervical lymph nodes more than 9 years after the initial presentation. Cells from the tumour and metastasis immunostained with antibodies to prolactin and growth hormone, even though there was no clinical or biochemical evidence that the tumour was secreting prolactin or growth hormone. In addition, ultrastructural studies showed a monomorphic tumour with secretory granules much smaller than those normally associated with prolactin and growth hormone secretion. The clinical and pathological features suggest that the tumour is probably an acidophil stem cell adenoma, which although known to be aggressive in its clinical behaviour has not been previously reported to metastasize.
