Pigmented tumors resembling cutaneous melanoma were first reported in Sinclair miniature swine in 1967. Since that time, carefully planned breeding has established that this is an inherited malignancy the natural history of which mimics human cutaneous melanoma in a number of ways. Because of these characteristics, miniature swine melanoma appears to be an effective model with which to investigate the mechanisms influencing initiation, growth, and progression of human melanoma. This investigation characterized histologically the cutaneous melanoma in miniature swine and compared the findings with human neoplasm. Primary cutarteous melanoma in swine has been reclassified and standardized according to the classifications currently in vogue in human melanoma. Our results suggest that the condition in minlature swine is histologically similar to that in humans. These observations will provide a basis for interpretation of the results derived in the biologic studies performed in this model.
