Hello everyone.
0:02
Dr. Sidney Levy here, continuing our discussion of the
0:05
diagnosis and staging of laryngeal squamous cell malignancy.
0:10
I'm at the level of the subglottis at the moment.
0:12
I've been using this large transglottic tumor as an
0:15
example for us to see how tumors in this region spread.
0:20
Subglottic tumors tend to spread
0:23
in one of four or five ways.
0:26
There tends to be a pattern of circumferential
0:29
spread, so sometimes all you will see is a
0:33
circle or partial circle of tumor internal to the
0:38
cricoid ring involving only the subglottic mucosa.
0:43
They can also spread in a cephalad fashion to involve
0:47
the true vocal cords or indeed the supraglottis.
0:51
Sometimes they spread anteriorly directly
0:54
through structures such as the cricothyroid
0:57
membrane or the cricotracheal membrane.
1:01
And they can also spread directly posteriorly into
1:04
the cricoid cartilage and the cervical esophagus.
1:09
Lastly, uncommonly, they may also
1:12
spread, uh, inferiorly into the trachea.
1:16
In this case, the tumor is primarily situated
1:19
within the supraglottis and the glottis, and
1:23
the subglottis has been the destination of
1:26
spread rather than the origin of the tumor.
1:29
Last thing to consider is the differential
1:31
diagnosis of subglottic tumors.
1:33
These are glottic tumors, and the best thing to do there
1:37
is to try and identify the level of the commissures and
1:40
the true vocal cords and make an assessment as to whether
1:43
you think the tumor is centered at the level of the
1:47
glottis or below that at the level of the subglottis.
1:51
You can also see conditions as with other laryngeal
1:55
tumors such as, uh, chondroid tumors, chondrosarcoma,
2:00
or autoimmune conditions such as
2:02
rheumatoid arthritis, sarcoidosis.
2:06
Rarely, trauma may be mistaken for a tumor if
2:09
there has been a traumatic event to the larynx.
2:13
Sometimes, uh, the way in which
2:15
that heals can look tumor-like.
2:18
And lastly, minor salivary gland malignancies
2:21
such as adenoid cystic carcinoma can also,
2:24
uh, be present in the subglottis, and often
2:27
this diagnosis is made by the pathologist.
