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.
