Abstract
Here we describe the first case report of an hemangiosarcoma in a male blue-fronted amazon parrot (Amazona aestiva). The mass was localized near the inferior portion of the right orbit. A fine needle aspiration biopsy (FNAB) was performed and a presuntive diagnosis of hemangioma/hemangiosarcoma was established. Further histopathological evaluation revealed a mesenchymal neoplasm composed basically by well formed vascular channels lined by pleomorphic endothelial cells. Thus, the final diagnosis was a well-differentiated cutaneous hemangiosarcoma.
Highlights
RESUMO – Aqui se descreve o primeiro caso de hemangiossarcoma em um macho de Papagaio verdadeiro (Amazona aestiva)
Is characterized by pleomorphic endothelial cells aligned on multiple collagen trabeculae that forms bloodfilled vascular spaces of variable sizes (Maxie, 2007)
In psittacines birds the neoplasm has been described in Melopsittacus undulates (Freeman et al, 1999), Pionus spp., Agapornis spp., Psittacus erithacus (Reavill, 2004), Primolius auricollis (Reavill, 2001), Nymphycus hollandicus (Sledge et al, 2006), Amazona ochrocephala oratrix (Hanley, 2005), A. farinosa (Rossi, 1998), A. amazonica (Mickley et al, 2009), and already described in A. aestiva (Godoy et al, 2009)
Summary
RESUMO – Aqui se descreve o primeiro caso de hemangiossarcoma em um macho de Papagaio verdadeiro (Amazona aestiva). Is characterized by pleomorphic endothelial cells aligned on multiple collagen trabeculae that forms bloodfilled vascular spaces of variable sizes (Maxie, 2007). It is locally invasive and multicentric tumor that tends to present with inflammation and necrosis. We describe the first case report of an hemangiosarcoma in a bluefronted amazon parrot (Amazona aestiva).
