WOMBATS

Neoplasia in wombats is rare. Reported malignancies include mammary and biliary adenocarcinoma (Munday 1988) and two cases of lymphoid neoplasia in a zoo-housed bare-nosed wombat (Vombatus ursinus) (Skerratt 1998) and a free-ranging southern hairy-nosed wombat (Canfield and Cunningham 1993). Benign neo­plasms have been limited to the skin, with a case of cutaneous fibropapilloma in a bare-nosed wombat with concurrent sarcoptic mange (Bryant and Reiss 2008) and a cutaneous tricholemmoma in a southern hairy­nosed wombat (ARWH 2018 case no. 12127.1). The tricholemmoma was excised and the animal remains free of neoplasia.
