Pleomorphic liposarcoma of the intrathoracic cavity in a meerkat (Suricata suricatta).

[pleomorphic liposarcoma]

Postmortem examination of a meerkat which had been captive for eight years in zoo , revealed multinodular white masses filling the thoracic cavity with systemic metastasis . Microscopically , the neoplastic cells were polygonal to spindle-shaped and had eosinophilic cytoplasm often with variable numbers of small lipid droplets . Immunohistochemically , the neoplastic cells were intensely positive for vimentin and occasionally weakly positive for S-100 . Ultrastructurally , several lipid droplets without limiting membranes were observed in the cytoplasm . Based on the findings above , the tumor was diagnosed as a pleomorphic liposarcoma arising from the thoracic cavity . To date , neoplasms have seldom been reported in Herpestidae animals . To the authors ' knowledge , this is the first reported case of liposarcoma in a meerkat .
