combined classical carcinoid and goblet cell carcinoid tumor
Monday 6 September 2010
Definition: Carcinoid tumors are the most common neoplasms of the appendix. Histologically they have been categorized as classical, tubular, or goblet cell types.
Goblet cell carcinoid has been regarded as a distinctive tumor type, not related to classic carcinoids. Combinations of these 2 tumor types have rarely been described. (20631606)
The occurrence of both carcinoid types in the same appendices suggests a closer histogenetic relationship than previously believed, although the possibility that the 2 components represent separate, independent primaries ("collision tumors") can also be considered.
