Paratesticular sarcomas: two cases with different evolutions.
[liposarcoma]
Paratesticular
sarcomas
are
rare
and
account
for
less
than
1
%
of
all
adult
sarcomas
.
Intrascrotal
tumours
can
be
testicular
or
paratesticular
,
paratesticular
tumours
being
rarer
(
7
-
10
%
)
.
Only
30
%
of
paratesticular
tumours
are
malignant
and
90
%
of
these
are
sarcomas
.
Histological
subtypes
include
leiomyosarcoma
,
rhabdomyosarcoma
,
liposarcoma
and
undifferentiated
high
-grade
pleomorphic
sarcoma
.
Recurrence
is
frequent
in
this
type
of
tumour
and
can
occur
years
from
initial
diagnosis
.
These
reports
show
two
cases
of
paratesticular
sarcoma
with
very
distinct
evolutions
.
The
first
case
concerns
a
patient
who
presented
with
low
-grade
leiomyosarcoma
with
two
local
recurrences
treated
with
surgery
,
and
distance
recurrence
with
cutaneous
,
subcutaneous
,
pulmonary
and
hepatic
metastasis
30
 
years
after
surgery
of
the
primary
tumour
.
The
second
case
reports
of
a
patient
who
presented
with
high
-grade
myxoid
liposarcoma
with
local
and
distance
recurrence
3
 
years
after
surgery
of
the
primary
tumour
,
which
progressed
after
chemotherapy
;
the
patient
died
7
 
months
after
diagnosis
of
recurrence
.
