neoplasms in corals

Dear Colleagues,

Have you heard anything related to cancer in corals recently? The 
most substantial paper I've got was written by Dr. Esther Peters and 
co-workers in May 1986. The text is of excellent quality and 
very informative, although the report does not fully conclude the 
causes of coral tumours (calicoblastic neoplasms).

I am asking this because last month, during a field work, I 
discovered abnormal tissue growth in colonies of two scleractinians 
(Northern coast of the State of Bahia, Brazil). The area has been 
monitored since 1995, but I never noticed scleractinians with chaotic 
porous proliferation, hyperplasia, irregular shape and discolouration 
(Not the usual bleaching).  I suspect that this is a consequence 
of reef degradation following the 1997-98 El Nino event. However,  
most of literature I could track down is out of date. 

If you are/know someone who is currently engaged in coral tumour 
research, please contact me.  I also appreciate comments and 
suggestions from everyone.

Cheers, Francisco.
