The

has
been caused
by a

The
variably sized lymph channels
have
produced multiple nodules
on the
surface
of the
tongue.

The
patient
died from malignant lymphoma,

this
was an
opportunistic

Pleomorphic
adenoma
of
parotid
gland.
F/52.
The
multilobulated
appearance
of
this
tumour
is
shown.
It
must
be
removed together with some surrounding parotid gland,
or
else
some
of the
irregular projections around
its
margins will
be
left
behind
and the
tumour will recur.

Warthin's
tumour
(adenolymphoma)
of the
parotid
gland.
M/63. These
tumours
are
multicystic.
The
cysts
are
filled with mucus,
as
indicated. They
are
benign tumours
and
are
the
second most frequent tumour
of the
parotid gland,
following
pleomorphic adenoma.

Tracheo-oesophageal

Newborn child.
The
upper

oesophagus terminates
as a
blind pouch.

The
lower half
of the
abnormality shown
in
Figure
4.17.
The
distal
end of the
oesophagus opens into
the
trachea
just above
the
carina.
Fig. 4.19 This shows
the
entire abnormality, with
a
blindly
ending upper oesophageal pouch (arrowed)
and the
lower part
of
the
oesophagus opening into
the
trachea proximal
to the
carina. There
are a
number
of
different types
of
tracheo-
oesophageal fistula. This
one is the
most common.

malignant lymphoma.
The
thick, greenish membrane
is

of
Candida
hyphae
and
purulent exudate.

tumour
is
intact.
Fig. 4.26 Squamous
cell
carcinoma
of the
lower
third
of
the
oesophagus.
M/61. Note
the
heaped
up,
ulcerated lesion
with
an
irregular edge.
The
oesophagus
has
been opened
to
display
the
tumour, which involves almost
the
whole
circumference
of the
oesophagus.
As the
tumour grows
it
narrows
the
lumen, resulting
in
dysphagia,
the
presenting
symptom
of
carcinoma
of the
oesophagus.

extensive ulceration
in
this
tumour.

Oesophageal
stricture.
F/51. Surgical specimen.
The
oesophageal wall
is
fibrotic
and the
lumen
is
greatly reduced. This
resulted from swallowing caustic soda with suicidal intent.

Megaoesophagus
due to
achalasia
of the
lower
end. M/84.
Every
day for the 30
years before
his
death
the
patient
had
swallowed
a
mercury-filled rubber bougie
to
dilate
the
lower
end of his
oesophagus
and
relieve
his
symptoms
of
dysphagia.
He
had
suffered from
a
number
of
episodes
of
aspiration pneumonia
before
the one
that finally caused
his
death.
