title: Endocervical polyp with pseudosarcomatous pattern and cytoplasmic inclusions: an electron microscopic study.
abstract: A case of endocervical polyp with atypical stromal cells in a 32-year-old woman is reported. Light microscopy showed atypical stromal cells with eosinophilic cytoplasmic inclusions which, by electron microscopy, were nonmembrane-bound, compact fibrillary structures in close relationship with the cytoplasmic microfibrils. The ultrastructural features demonstrated a fibroblastic nature of bizarre cells. These inclusions are similar to those of infantile digital fibromatosis. These findings have not been reported previously.
