Large cell neuroendocrine carcinoma of the cervix and right ovary (Figure 1E), infiltrating the full thickness of the cervix, with vascular and nerve invasion; (cervix and cervical canal, posterior vaginal fornix, part of the uterine body) showed high-grade squamous intraepithelial lesion (HSIL/CIN III) involving glands; margins were tumor-free: cancer nodules found in the perivesical fibrofatty tissue (3 nodules): Immunohistochemistry: CD56 (+) (Figure 1F), Syn (partly +) (Figure 1G), P16 (+), EGFR (+) (Figure 1H), TTF-1 (-), CK5/6 (-), Ki-67 (+, about 70%); 2. This evidence concerns the gene NCAM1 and large cell neuroendocrine carcinoma.
