In
1968
,
Bart
et
al
____________________
10
cases
____________________
an
uncommon
acquired
growth
that
was
located
on
the
fingers
.
Although
it
clinically
resembled
a
cutaneous
horn
____________________
rudimentary
supernumerary
digit
,
it
had
distinct
histopathological
findings
.
The
authors
named
this
growth
acquired
digital
fibrokeratoma
(
ADFK
)
.
Subsequently
,
Pinkus
reported
28
more
cases
;
however
,
these
lesions
occurred
not
only
on
the
fingers
,
____________________
also
on
the
proximal
hand
,
toes
,
sole
,
____________________
one
in
the
prepatellar
region
.
For
this
reason
,
Verallo
et
al
suggested
the
entity
might
more
appropriately
be
____________________
an
acral
fibrokeratoma
.
Similar
growths
have
been
____________________
to
occur
in
the
subungual
or
periungual
region
of
patients
with
tuberous
sclerosis
,
and
they
are
____________________
to
as
Koenen
tumors
or
garlic
clove
fibromas
.
They
differ
,
however
,
in
that
they
tend
to
be
multilobulated
and
involve
several
digits
and
,
histologically
,
may
have
atypical
stellate
myofibroblasts
.
