Neoplasia has been found in the livers of bottom-feeding fish taken from heavily contaminated freshwater and marine habitats. This study examined the progressive development and ultimate diversity of liver neoplasia in winter flounder (Pseudopleuronectes americanus) from Deer Island Flats, Boston Harbor, MA., U.S.A., and encompassed histopathology, ultrastructural pathology.
Liver lesions including neoplasia and hydropic vacuolation have been described in winter flounder (Pleuronectes americanus) from sites in Boston Harbor, and were highly prevalent near the Deer. Winter flounder were captured by scuba divers from an area adjacent to a sulfite pulp and paper mill and from a reference site and the tissues examined for lesions.
Severe hyperplasia of the gills, focal vacuolation in the liver, and multifocal hemosiderosis in the spleen and liver were most pronounced in large, adult fish collected near the by: Winter flounder (Pleuronectes americanus) from Boston Harbor, Massachusett, undergo a progressive series of hepatic changes involving hydropic vacuolation of epithelial cells, biliary hyperplasia, and hepatocellular and cholangiocellular neoplasia.
Severely affected fish often exhibit grossly visible by: 8. In 12% of the adult winter flounder in Boston Harbor exhibited hepatic neoplasms and up to 80% had hepatic hydropic vacuolation (HV).
Tumor prevalence fell to % and HV to. Hepatic changes that include hepatocellular and cholangiocellular neoplasia are prevalent in adult winter flounder from Boston Harbor, Massachusetts.t The syndrome includes local and diffuse aggregations of abnormally vacuolated hepatocytes and cholangiocytes, previously described as hepatotoxic cells,t which form the predominant non- neoplastic lesion by: For both species, hydropic vacuolation of biliary epithelial cells was the most prevalent liver lesion detected and was statistically associated with sediment and tissue concentrations of PAHs or their metabolites, PCBs, DDTs, chlordanes and by: Liver lesions including neoplasia and hydropic vacuolation have been described in winter flounder (Pleuronectes americanus) from sites in Boston Harbor, and were highly prevalent near the Deer Island sewage outfall.
A marked decline in prevalence of neoplasia has been seen over the period to in fish from near the Deer Island by: Vacuolation, proliferation and neoplasia in the liver of Boston Harbor winter flounder (Pseudopleuronectes americanus).

PhD Dissertation, Massachusetts Institute of Technology, Woods Hole Oceanographic Institution. Woods Hole, by: Liver neoplasms, including hepatocellular and cholangiocellular tumors, commonly occur in winter flounder (Pleuronectes americanus) caught from some chemically contaminated areas such as Boston Harbor.
Hydropically vacuolated cells, very often associated with neoplasia in winter flounder liver, appear to represent the first cellular abnormality in animals that later develop frank by: In this study, ODC was utilized as a biochemical indicator for cell proliferation to characterize proliferative hepatic lesions in 24 Boston Harbor winter flounder (Pleuronectes americanus).
