Acetylcholinesterase and HHV-8 in squamous cell carcinoma and retinoblastoma.
Acetylcholinesterase (AChE) and human herpesvirus type 8 (HHV-8) antigens were studied in tissue sections from 56 squamous cell carcinomas (SCC) and five retinoblastomas (Rb). Approximately 62.5% of SCC and 80% of Rb showed positive staining for AChE. AChE staining in tumors was much higher than in normal control tissue. However, only 21.4% of SCC and 60% of Rb contained HHV-8 antigens. Of the 56 SCC, 17.9% were positive for both AChE and HHV-8 antigens, whereas 60% Rb were positive for both markers. The co-existence of AChE and HHV-8 antigens may play a role in the development of SCC and Rb. A possible mechanism for the development of these tumors is discussed.
