Abstract

Large cell neuroendocrine carcinomas (LCNECs), one of the four newly categorised endocrine tumors of the uterine cervix, are unusual and aggressive tumors. The present report describes a case of LCNEC diagnosed at an early stage and associated with cervical intraepithelial neoplasia (CIN). The LCNEC showed organoid and trabecular growth patterns and was positive for chromogranin and synaptophysin. The CIN lesion was of a high grade and was negative for these neuroendocrine markers. Polymerase chain reaction (PCR) using genomic DNA extracted from archival tissue demonstrated human papillomavirus (HPV) type 16 DNA in both the LCNEC and CIN lesions. These histological, immunohistochemical and PCR findings suggested that the LCNEC lesion was distinct from the CIN lesion and that both resulted from the carcinogenic field effect of HPV 16.
