Relationship between cytokeratin staining patterns and clinico-pathological features in somatotropinomae.
OBJECTIVE Somatotropinomae are classified as densely and sparsely granulated adenomae, which typically exhibit a perinuclear pattern (PP) and a dot pattern (DP) in cytokeratin (CK) immunostainingExpand
