Argentaffin tumor occurring in a benign cystic teratoma of the ovary

Abstract

A F F I N tumors have been reported with increasing frequency during the past two decades in association with various portions of the gastrointestinal tract, particularly of the appendix and ileum. Tumors of identical histology have also been described in connection with the lower respiratory tract and have been designated as the carcinoid type of bronchial adenoma.6 It is conceded that these neoplasms may show low-grade malignant characteristics and that numerous instances of metastases to regional and distant organs have been reported, but the tumor rarely is fatal in outcome unless some complication, such as intestinal obstruction, supervenes.3
