Metastatic Small Cell Neuroendocrine Carcinoma of the Liver from the Uterine Cervix

We present the cytologic features of small ceil neuroendocrine carcinoma of the liver metastasized from the uterine cervix. Cytologically, tumor cells were arranged in a pattern of solid sheet in necrotic background. The tumor cells were characterized by uniform, small cells, round hyperchromatic nuclei, and high nuclear cytoplasmic ratio. The smears showed frequent mitotic figures and rosette formation. These findings were identified with the previous histologic sections of uterine cervix. To make a diagnosis of metastatic small ceil neuroendocrine carcinoma on the Papanicolaou smear, a high index of suspicion and careful review of clinical history are needed.
