proximately 15 years before his death This progressed slowly but steadily so that ..
during his last few years of life he was almost completely exhausted after climbing . a

He had
frequent bouts of coughing which were especially <4we=

severe in the morning but occurred throughout the day and night This was pro- 2
ductive of moderately large amounts of sticky brown sputum which was never ~ eogs
ssras streaked
During the spells of coughing wheezing noises in his chest could

be heard many feet away After several years he was examined by a physician ae ~-

lungs There was no history of cyanosis orthopnea paroxysmal dyspnea angina7

The patient had been employed by a manufacturer of asbestos products since the age of 23 years until a few months before his death During the first 25 years of this period he was employed as a coverer the same occupation as in case 1.x Although there was no known association between the two men the conditions under which they worked were essentially the same The patient's work called for
covering steam and water pipes with asbestos He was seldom in the same place
unventilated S25 for more than a few days or weeks but the the work usually was done in
cellars Large amounts of powdered asbestos cement were used in addition to the asbestos fabric The patient's son worked with his father for a year but quit because the air was too dusty and because several of the employees were getting ena

* ,.- Nordmann presentedin tabular form the relevant
on his own
two data "
cases of pulmonary asbestosis and carcinoma and of the four cases
:previously recorded After analyzing the results he came to the con_
-
- clusion that pulmonary cancer is an occupational disease among asbes-
~tos workers Gloyne in a recent text stated that no definite conclu- :
=. sions can be drawn on the relation between these two diseases until
material is available Table presents a tabulation similar to...
~~ Nordmann'sNordmann's but brought up to date by the addition of four cases in

evidence _ the incidence - It may be of interest to review briefly for comparison
of carcinoma in the material examinedin this department The figures
are derived from the autopsy material of a general city hospital forfor
acute illnesses with 696 beds of which 498 are devoted to adults In
total of 2,451 routine autopsies performedin a year period there
were 401 instances of carcinoma of all types Thisis an incidence of
16.36 per cent Of these 59 were bronchiogenic comprising 14.71 per
cent of all carcinomas and 2.41 per cent the routine autopsies It
was striking although naturally of no statistical significance to find
bronchiogenic carcinoma in the only two cases of pulmonary asbestosis
seen here

CONCLUSIONS
1. Two cases of bronchiogenic carcinoma in association with pul-
monary asbestosis are presented
2. An attempt to demonstrate unusual amounts of silicain the lungs
of both cases was unsuccessful
3. An explanation for the absence of elevated silica values in the
presence of asbestosis is offered
4. The relevant data of all reported cases of pulmonary asbestosis
presented and carcinoma are
in tabular form
