Coexistence of cervical extramedullary plasmacytoma and squamous cell carcinoma: A case report.

Background: Extramedullary plasmacytoma (EMP), a variant form of myeloma, is a rare solid plasma cell tumor that originates from the bone marrow hematopoietic tissue and accounts for about 3% of all plasma cell tumors. EMP can affect various tissues and organs, about 90% of which is found in the head and neck. However, EMP in the reproductive organs is rare, and is difficult to be distinguished from other primary or metastatic genital tumors according to clinical symptoms and imaging findings.

Insulin, glucose and hepatocellular carcinoma risk in male hepatitis B carriers: results from 17-year follow-up of a population-based cohort.

This study aimed to investigate the association of fasting insulin and glucose levels with hepatocellular carcinoma (HCC) risk in a case-cohort study within a cohort (1989-2006) of 2903 male government employees chronically infected with hepatitis B virus (HBV) in Taiwan. Insulin, glucose and HBV-related factors were assayed in baseline plasma among 124 HCC cases and a random subcohort of 1084 of the total cohort. After adjustment for demographics and HBV-related factors, including viral load and genotype, the HCC risk was higher for the highest [>6.
