Giant recurrent retroperitoneal liposarcoma initially presenting as inguinal hernia: Review of literature.
[well-differentiated liposarcoma]
Liposarcomas
comprise
around
15
%
of
soft
tissue
tumors
.
These
tumors
of
mesodermal
origin
arise
as
single
tumors
,
present
one
histologic
type
and
diverse
locations
(
including
the
retroperitoneum
)
.
Diagnosis
of
liposarcomas
of
retroperitoneum
is
difficult
because
of
this
unspecific
presentation
and
in
50
-
100
%
of
the
cases
there
is
recurrence
from
residual
tissue
.
An
86
year
old
male
patient
was
admitted
in
1996
due
to
a
right
and
voluminous
inguinal
hernia
.
During
the
herniaplasty
,
a
right
paratesticular
tumor
was
isolated
and
removed
.
The
histologic
exam
revealed
a
well-differentiated
liposarcoma
.
A
CT
scan
was
performed
and
a
large
abdominal
mass
was
detected
.
The
patient
underwent
a
laparotomy
and
an
incomplete
resection
of
the
tumor
was
achieved
.
After
the
surgery
the
patient
remained
asymptomatic
during
a
long
period
.
Nine
years
later
,
the
patient
underwent
another
laparotomy
with
partial
removal
of
the
giant
recurrent
retroperitoneal
liposarcoma
.
The
purpose
of
this
publication
is
to
report
the
recurrence
of
giant
retroperitoneal
liposarcoma
,
which
is
an
unusual
presentation
in
surgery
today
.
Furthermore
,
we
would
like
to
emphasize
the
long
-term
survival
of
this
patient
despite
partial
resection
and
the
possibility
of
performing
a
re
-resection
in
this
type
of
cases
.
