Population dynamics and interagency management of the bloater (Coregonus hoyi) in Lake Michigan, 1967-1982

Abstract

A case of a favourable outcome of spindle-cell medullary carcinoma of the thyroid is reported. Electron-microscopically, there was no correlation between histological and ultrastructural differentiation. The tumor consisted mainly of ultrastructurally differentiated cells with endocrine granules which may be the cause of the favourable prognosis.
