Malignant carcinoid of the pancreas: a cytologic, ultrastructural, and immunocytochemical study of a case diagnosed by fine-needle aspiration of a supraclavicular node metastasis.
Carcinoid tumor of the pancreas is extremely rare. This article describes the case of a 22-year-old woman who manifested a typical carcinoid syndrome; a definitive diagnosis of a metastatic carcinoid tumor was made from needle aspiration of a supraclavicular lymph node using morphologic, immunocytochemical, and ultrastructural criteria. The carcinoid tumor was subsequently shown to be of pancreatic origin.
