Primary pituitary carcinoma: a clinical pathological study.
A 60-year-old woman presented with a history of headache and rapidly progressive complete bilateral ophthalmoplegia. Her endocrine function was normal. Radiographic studies revealed signs of diffuse destruction of the sella turcica by a tumor without suprasellar extension. Biopsies of the lesion within the sphenoid sinus demonstrated the presence of a primary pituitary carcinoma; autopsy findings revealed metastatic deposits in the liver, kidney, and lung. The histological characteristics of these cells and the electron microscopic findings confirmed that the tumor can first manifest themselves by the rapid development of unilateral or bilateral ophthalmoplegia; this diagnosis should be considered in all individuals with such a syndrome.
