Large liposarcoma developing in the ischiorectal fossa: Report of a rare case.
[well-differentiated liposarcoma]
We
herein
report
an
extremely
rare
case
of
a
liposarcoma
developing
in
the
ischiorectal
fossa
that
was
completely
resected
using
a
transsacral
approach
.
A
74
-
year
-old
man
was
admitted
to
our
institute
because
of
a
large
perianal
tumor
.
A
pelvic
magnetic
resonance
imaging
(
MRI
)
revealed
an
8
cm
×
7
cm
×
5
cm
sized
encapsulated
heterogeneous
tumor
on
the
right
side
of
the
ischiorectal
fossa
.
Transsacral
excision
was
performed
under
a
diagnosis
of
liposarcoma
.
The
tumor
was
partially
fixed
to
the
external
sphincter
and
puborectalis
.
Therefore
,
the
muscles
were
partially
resected
to
ensure
sufficient
margins
.
Histopathological
examination
revealed
a
well
differentiated
liposarcoma
and
negative
surgical
margins
.
The
basic
treatment
strategy
of
liposarcoma
is
surgical
resection
,
whereas
the
effects
of
chemotherapy
or
radiotherapy
remain
limited
.
Although
no
postoperative
adjuvant
therapy
has
been
performed
in
our
case
,
no
recurrences
have
occurred
for
1
year
after
surgery
.
Although
the
curative
resection
of
large
tumors
located
in
the
ischiorectal
fossa
is
usually
difficult
,
the
complete
resection
of
liposarcoma
is
the
main
potentially
curative
treatment
.
A
transsacral
approach
is
useful
for
a
complete
resection
.
