Alteration
of the
facial
appearance
can
also
be
caused
by
underdevelopment, atrophy
or
enlargement
of the
various
constituents
of the
face.
An
overall thinning
of the
face,
particularly
of the
temples,
may be a
reflection
of
gen-
eralized
wasting. Although
the
presenting complaints
and
the
subsequent clinical assessment
can
lead
to a
correct
diagnosis
from
the
many possibilities that cause wasting
(e.g.
malignancy, malabsorption, gastrointestinal disorders,
chronic infections, etc.), some cases
may be
seen initially
with
an
unrelated complaint. Among
these
are
malnutri-
tion caused
by
social
deprivation
(1.328), malabsorption
and
Crohn's disease (1.329). Patients with anorexia
nervosa
often insist that they
are
eating well, many even
believe that they
are
overweight,
but
their
facial
features
suggest
undernutrition (1.330).
Neuromuscular disorders including
facial
hemiatrophy
have
been
discussed
earlier
in
this
chapter
(p.
29).
Loss
of
facial
fat may
make
the
normal muscles look prominent
in
lipodystrophy
(1.331;
see
also 1.15
and
1.16).
Asymmetry
of
the
face
may be
caused
by
facial hemiatrophy (see
1.145),
or by a
cavernous
haemangioma
(1.332).This
lesion
is
not
present
at
birth
but
appears during childhood.
A
cavernous haemangioma
is a
deep,
vascular malformation
characterized
by a
soft
compressible deep-tissue swelling
and
surface varicosities.
