Historically misunderstood to be rare and relatively benign, @entity5 ( @entity5 ) are increasingly common and are now regarded as @entity5 that can cause debilitating symptoms and potentially life threatening issues for @entity1 . @entity5 are a heterogeneous group of separate clinico-pathological entities that share a common characteristic i.e. expression of endocrine differentiation potential. In the ovary, the term "neuroendocrine" relates mainly to widely-known @entity4303 , but it may also be applied to @entity3270 of @entity1149 of @entity358 . @entity43 develop in pure form or in association with other @entity5 , mainly @entity44 . They originate from endocrine cells, either of teratomatous origin or possibly also indigeneous. Ovarian @entity3270 belong most probably to surface @entity2785 , which express endocrine pathway of differentiation. The @entity3270 of non-smallcell type are characterized by the presence of islands, sheets, and trabeculae with little intervening stroma (organoid growth pattern) and cellular homogeneity. However, they are higher-grade than @entity4303 . Primary @entity43 of the @entity358 do not differ histologically from their counterparts in other organs. They are composed of small cells with scanty cytoplasm and oval to spindleshaped nuclei.
