The mass was surgically excised, with reoccurrence to the same site 88 days later. A second surgical excision was performed, and the rabbit died 3 weeks later from respiratory distress. At necropsy, multiple varying-sized masses were observed in the ventral mandibular region and throughout the lungs, pleura, and diaphragm. On histopathology, the masses were composed of moderately anisocytotic and anisokaryotic polygonal to spindloid cells with moderate finely granular, lightly eosinophilic cytoplasm, having round to oval nuclei with one to several nucleoli and finely stippled chromatin. Mitotic figures were frequent. Lymphatic and venous invasion were noted with neoplastic cells metastasized to the submandibular lymph nodes, lungs, liver, and adventitial surface of the aorta. Fontana-Masson stain was negative for melanin, thereby necessitating immunohistochemistry and transmission electron microscopy. Positive staining with MART-1 (a melanocyte protein marker) combined with transmission electron microscopy revealing type II melanosomes confirmed the diagnosis of an amelanotic melanoma.<\/jats:p>","DOI":"10.1177\/0300985810369898","type":"journal-article","created":{"date-parts":[[2010,5,11]],"date-time":"2010-05-11T22:04:20Z","timestamp":1273615460000},"page":"977-981","source":"Crossref","is-referenced-by-count":16,"title":["Amelanotic Melanoma in a New Zealand White Rabbit (\n                    <i>Oryctolagus cuniculus<\/i>\n                    )"],"prefix":"10.1177","volume":"47","author":[{"given":"P.
