In

,
Santa
Cruz
and
Aronberg
first
described
targetoid
hemosiderotic
hemangioma
(
THH
)
,
which
is
a
____________________
vascular
neoplasm
that
some
have
postulated
may
represent
____________________
reactive
condition
.
Also
termed
hobnail
hemangioma
,
targetoid
hemosiderotic
hemangioma
typically
____________________
as
a
solitary
papule
affecting
the

Recognition
of
characteristic
features
____________________
important
to
avoid
misdiagnosis
,
as
clinically
and
histopathologically
,
targetoid
hemosiderotic
hemangioma

mimic
disorders
such
as
melanoma
,
Kaposi
sarcoma
(
KS

,
and
angiosarcoma

____________________
the
histology
of
targetoid
hemosiderotic
hemangioma
is
reproducible
,
____________________
clinical
features
variable
,
and
the
hobnail
phenomenon
not
specific
,
some
authors
favor
the
designation
of
"
superficial
hemosiderotic
lymphovascular
malformation
"
instead
of
HH
or
targetoid
hemosiderotic
hemangioma
.
