title: [Small cell structured cell nests of endometrial stroma].
abstract: Tissue from endometrial diagnostic curettage material may show small clumps of stromal cells, which are pushed together (stromal collapse) and present a picture of glandular and stromal breakdown. This can be misinterpreted as small cell structured carcinoma, possibly of neuroendocrine or basal cell origin. Immunohistochemical investigations (e.g. estrogen receptor, epithelial and neuroendocrine markers and proliferation markers) are helpful in identifying the correct differential diagnosis.
