[Coral-List] Coral Tumors?????

Gary is correct. Those of us who have been studying these diverse
lesions on corals have agreed that the best "field-identification name"
is "growth anomaly" (GA). To determine if the lesion is a tumor (which
means neoplasm, or cancer, malignant neoplasm), sections of both
skeleton and tissue are needed to examine cell and tissue changes that
meet the histologic criteria for neoplasia (versus hyperplasia or
altered growth response to presence of a parasite, for example), and on
these our group has agreed that more study is needed! However, I don't
advocate sampling a lesion unless growth rate data have been obtained
for a period of time first, because we need this information as well.
In Japan, growth anomalies have been studied, as reported in these papers:
Yamashiro, H., M. Yamamoto, and R. van Woesik. 2000. Tumor formation
on the coral Montipora informis. Dis. Aquat. Org. 41:211-217.
Yamashiro, H., H. Oku, K. Onaga, H. Iwasaki, and K. Takara. 2001.
Coral tumors store reduced level of lipids. J. Exp. Mar. Biol. Ecol.
Again, "tumor" is now considered not an appropriate term, although many
have used it in the sense of "a swelling" or "protuberant mass" (which
might not be a neoplasm at all).
The Registry of Tumors in Lower Animals is interested in further
sightings of and reports on similar lesions, with the goal of developing
diagnostic criteria and standardized terminology for them, as we are
doing for cellular proliferative disorders in other organisms (except
birds and mammals).
