The ultrastructure of 11 ovarian carcinoids was investigated. The 6 carcinoids with an insular pattern primary in the ovary or metastatic to it from the ileum displayed granules that were pleomorphic (dumbbell and reniform shaped) and varied from 90 to 410 μm, with an average diameter of 210 μm. Five trabecular carcinoids primary in the ovary or metastatic to it from the pancreas contained uniformly round granules with an average diameter of 185 μm and a range of 150–210 μm. These data confirm other reports that pleomorphic granules are typically associated with insular carcinoids of the midgut, and round granules with trabecular carcinoids of the foregut and hindgut.
