Peripheral nerve neoplasms, in addition to those from the Japanese 
tumor registry, include neurilemmoma in goldfish (RTLA 1889 from John 
Carney) and freshwater drum (RTLA 1891 from John Black). 
Pigment cell tumors included an invasive melanophoroma (RTLA 1847 
from Bill Ribelin) and a non-invasive melanophoroma (RTLA 1951 from 
John Comick) in brown bullhead, an erythrophoroma in a goldfish (RTLA 
1875 from Prince Masahito), multiple melanophoroma in Mexican axolotl 
(RTLA 1886 from Veniamin Khudoley and V. Eliseev) and a xanthoma in a 
gopher snake (RTLA 1955 frcan Michael Ryan). A melanophoroma in an 
Atlantic croaker (RTLA 1988 from Walter Kandrashoff) had a histologic 
appearance similar to, but less extensive than pigmented lesions in the 
glue croaker (RTLA 2003, 2008, 2027) from the Japanese tumor registry 
and the gulf croaker (RTLA 1708, 1709) from Alan Meams in 1977. Dr. 
Ikuo Kimura now calls these melanotic neurilemmoma. 
A lymphosarcoma frcan a South African clawed frog (RTLA 1996) was 
received from R. Verhoeff-de Fremery. This, and a similar previous case 
from Dr. Verhoeff-de Fremery (RTLA 1769) are especially significant 
because they are composed of expansive populations of uniform lymphoid 
cells presenting a clear-cut neoplastic picture. Some earlier reports 
of lymphosarcoma in this species were complicated by being composed of 
mixed cells including many histiocytes and containing acid-fast bacteria. 
Other hematopoietic neoplasms were in medaka (RTLA 1850 from Prince 
Masahito), black crappie (RTLA 1863, 1864 from John Hnath), roach (RTLA 
1878 from David Bucke), Burmese tortoise (RTLA 1879, 1880 from Sandra 
Emanuelson), reticulate python (RTLA 1960 from A. Heldstab), European 
flat oyster (RTLA 1855 from H. Grizel; RTLA 1940-1944, 1946 from George 
Balouet) and Pacific oyster (RTLA 1945 from George Balouet). 
Reproductive system tumors include a genetically controlled ovarian 
neoplasm in a fruit fly (RTLA 1890 from Bob King) which is transplantable 
to wild strains where it invades normal gonad. An organoid gonad neo¬ 
plasm in a goldfish/carp hybrid (RTLA 1893 from John Black) resembles a 
gonadoblastoma with some sertoli cell differentiation. 
Gonnective tissue tumors include a lipoma in a little tunny (RTLA 
1922 from Walter Kandrashoff), a fibrolipoma in a white sturgeon (RTLA 
1999 from Glint Stockley), a fibroma in a Pacific cutlassfish (RTLA 1854 
from Prince Masahito) and in a brown trout (RTLA 1884 from Nelson 
Boustead), a dermal fibrosarcoma in a finescale menhaden (RTLA 1848 from 
Allyn Johnson), a dermal fibromyxosarcoma in a ribbed newt (RTLA 1873 
from W. Janisch and Th. Schmidt), and a fibroma in the lung of a green 
sea turtle (RTLA 1856 from George Balazs). 
Excretory system neoplasms included a metastatic renal adenocar¬ 
cinoma in the leopard frog (RTLA 1874 from Bill Duryee), nephroblastoma 
in rainbow trout (RTLA 1985 from Gharlie Smith; RTLA 2011, 2015 from 
Japanese tumor registry) and the first known nephroblastoma in an eel 
(RTLA 2032 from the Japanese tumor registry).
