- Neoplasia is a documented occurrence across invertebrate taxa, but challenges remain
with regard to tumor diagnosis, identification, and treatment.
- Literature reports of neoplasia are frequent in mollusks and insects, infrequent in Cnidaria
and crustaceans, and are yet to be documented in Porifera and Echinodermata.
- The use of traditional methods of diagnosis in veterinary medicine is encouraged, but the
unique anatomy and tissue biology of each invertebrate taxon needs to be taken into
- Most neoplasms described in the invertebrate literature have been benign, and many
external lesions may be amenable to surgical resection.
