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
.
