agent could not be demonstrated, nor could the tu- 

 mors be transplanted to other goldfish (45). The 

 relationship of these growths to the subcutaneous 

 fibrosarcomas of goldfish cannot be determined from 

 the reports in the literature. A fibroma of the ovary 

 in a related species, the carp Carassius carassius 

 was reported by Freudenthal (52). The growth was 

 nodular, white, and did not adhere to surrounding 

 structures. Histologically the richly cellular paren- 

 chyma consbted of connective tissue, was not in- 

 filtrative, and contained no demonstrable parasites. 

 Bits of the tumor were inoculated intraperitoneally 

 into 2 other carp. One of these fish died on the fol- 

 lowing day; in the other no tumor tissue could be 

 fotmd when the animal was sacrificed 10 weeks later. 

 *The first report of a soft tissue tumor in a fish was 

 made by Crisp (33) at a meeting of the London 

 Pathological Society in December, 1853. The neo- 

 plasm was a fibroma weighing 4 pounds and loosely 

 attached to the peritoneum of a 10 pound carp. On 

 section it was found to consist of dense, white 

 bundles of fibrous tissue. The author called atten- 

 tion to the resemblance in origin and growth be- 

 tween thb tumor and some of the tree fungi, point- 



ing out that these excrescences, both in man and 

 the lower animals, pc»sessed a power of growth to 

 some extent indefx'ndent of the body to which they 

 are attached. 



Abatracta of other reported case* of fibroma 



Gesvais, 1876: A very large tumor was fouDd ocar 

 the ovaries in the abdominal cavity of a carp Cyprimms 

 carpio. Histologically it was composed of coonecttve 

 tissue. 



EasaTH, 1878: During a robbery at a fish hatchery 

 in Switserland, a large lake trout 5d/mo lacustris was 

 injured by a blow on the bead, but "the bursar failed 

 to capture the tasty morsd." Though it bled from the 

 wound, the fish was active and in a short time the 

 wound had fully healed. At the site of the scar a nodular 

 thickening developed which grew rapidly but remained 

 covered by a smooth, intact layer of epithelium. Ke- 

 tologicaUy the ttmior wm vascular, tte thane m^er 

 loose and somewhat i ria t inm» i b mmm aieat the mo- 

 piasro resembled gnmuiatioQ tissue. The aiKbor identi- 

 fied it u a ftbromrcoma. 



BLANi>-StrrTON, 1885: In a codfish Godms mm km 

 a fibrous tumor lay in the loose tissue beneath the dda 

 of the abdomen. The growth had undergone caldft* 

 catkm.
