As early as 1(33, \Weher' l)resented eviIeIlce suggesting thaltpersons exl)osed to the inhalatioin of dust or funmes of berylliumcompl)oun(ls miglt develop severe l)tlmonary symptoms. A formiiof relatively acute pieinmonitis, similar to that reportedI by Weberaind occurring in workers expose(I to the fumiles of the berylliumextraction I)rocess, was first reported in this country by VanOrdstrand et al' in 1)43. Addlitional case rel)orts have lheenI)resented sul)sequently.

In 1942, a femiiale employee of a mainufacturer of fluorescentlamp)s was autopsiedl followinig a I)rolonged illnless characterize(dlby insi(lious onset, weiglht loss, extreme dysl)nea during physicalexertion an(l a p)ersistent nonprodluctive cough.

PULMONARY GRANULoMNIATOSIS

progresses into the chronic granuloma. Moreover, this granulomahas not been reproduced in experimental animals exposed in nu-merous ways to various beryllium compounds, in spite of repeatedand continuing efforts to do so. Because of its uncertain etiologyand still unproven clinical or histologic specificity, this particulargranuloma has been designated as pulnmonary gr(aldtloinatosis ofbervllizint1workers.

The following case exemplifies the salient features of pul-moniary granulomatosis of beryllium workers:

J. A. was a 58 year old white male of German descent, whosefamiiily history and past personal history has no apparent bearingupon the present illness. Until September of 1947, he had beenwell and vigorous but at that time he noted that he was losingweight in spite of a normal appetite, and in the ensuing threemonths his weight dropped from a previous stable level of 220pounds (height, 68 inches) to 150 pounds. No constitutionalsigns such as fever or night sweats, or even a feeling of illness,accompanied the loss of weight. In January of 1948, he firstnoticed breatlhlessness at an unusually low intensity of effort, andby February he was forced to stop in order to regain his breathat the top of one ordinary flight of stairs, climbed at a slow speed.At the same time, he began to have severe paroxysms of coughwhen he exerted himself and he raised about 4 tablespoons ofwhite tenacious material daily. Sudden changes of position, fromrecumbent to erect or vice versa, would also initiate a paroxysmof cough. Cyanosis of his nail beds was first nioticed by thepatient in January of 1948. A roentgenogram in Mlay of 1948showed a fine stippling in the lower two thirds of each lung field.From June of 1948 on, he rested at home. Nevertheless, he feltno l)etter even though he gained 25 pounds of l)ody weight. Hedenied chest p)ain, hemoptysis, palpitation, orthopnea, nocturia.edema, or gastro-intestinal symptoms.

His occupational history was irrelevant as to the inhalationof dust until 1943, from which time he was employed as anelectrician in a foundry that makes, among other things, beryllium

copper castings. This mzani had anmple exposture to fumes andduist atten(Iing the manufacture and processing of beryllitum copper.

Physical exanmination in September of 1948 revealed the fol-lowing abnormalities: cyanosis of nail beds, ear and nose; respira-tory rate at rest of 26 per minute, each excursion being shallow;chest expansioin very limilitedI on b)oth sides; a few persistent raleswere audible at the base of both lungs posteriorly; the pulmonicseconid souind was louder than usuial; during miiild exercise, the

resp)iratory rate was markedlly augmented. ,A roentgenogramii ofthe chest showed a diffuse fine granulationi or stippling throtughoutboth lungs as is shown in Fig. I. The hilar regions appeared tobe the site of enlarged lymph nodes. A film taken at the endof force(d expiration indicatedl that the lungs emptied well (Fig. I).

Oin AMay 20, 1949. he entered a hospital l)ecause of extremedvspnea, cyanosis and a temperature of 102 F. His capillaryblood at this time contained 6.54 million red cells, 18 grams ofhemoglobin and 18.5 thousand leucocytes per cimiml. He expiredon M\ay 21, 1949, approximately 21 months after the onset ofsymptoms. At necropsy. the examiner noted that the body didnot show signs of wasting but appeared to be that of a wellnourished man. The spleen was enlarged. The right pleuralsac contained 1.0 liter of amber fluid. Both lungs were moderatelyadherent to the chest wall. The tracheobronchial and mediastinalnodes were enlarged. The heart appeared enlarged, weighing390 grams. The left ventricle wall measured 16 mm. in thicknessand the right ventricle wall measured 7 mm. in thickness, the latterchamber appearing to be dilated. No abnormality of heart valvesor coronary vessels was noted. There was a firm laminated andpartially recanalized clot attache(d to the wall and occluding themain left pulmonary artery. No site of origin of an emboluscould be discovered, but it is worthy of note that the patient gavea definite history of phlebitis with edema and varicose ulcers tenyears and again two months before death. The occlusion of thepulmonary artery was obviously not a recent event. The cutsurface of the lungs after fixation showed an excess of solid tissuethroughout the entire parenchyma, the alveoli being relativelyscarce and coarse. There was marked thickening of the inter-lobular tissue. Both lungs were involved throughout with no grossevidence of focal areas of normal lutng tissue. The most strikingthink about the autopsy was the extensive distribution of the ab-normality as compared to the roentgenographic evidence. Thegross anid histological report of the lunigs andl tracheobronchiallymiiph nodes by Dr. A. J. Vorwald* is as follows:

GROss DESCRIPTION

LEFT LUNG: The left lung is of about normal size, and the lobesappear of normal relative sizes. Over the upper half, anteriorly and laterally,the visceral pleura is thickened and pearly white and smooth. It measures

in each case both during rest and exercise. This was true evenin the two cases who were completely asymptomatic at the timeof our examination. It is obvious that a significant proportiollof the pulmonary artery blood flow enters the left atrium in-completely arterialized. There is no evilence of an anatomicalshunting of blood around the alveolar capillaries and except ina very few, there is no evidence of a poor dlistribtution of gasesin the alveoli. Furthermore, the alveolar P02 is consistently high.These facts, together with the appearance of the alveolar wallwhen examined histologically, strongly favor the view that thereis an impediment to the passage of oxygen across the membraneseparating the gas from the blood phase. The imIpediment tooxygen diffusion across the alveolar wall appears to be the criticaland fundamental abnormality of this disease. In essence, thesepatients behave at sea level as would a normal man at an elevationof 10 to 15 thousand feet. If the lung becomes sufficientlysclerosed and resistant to distention, the already overblrdenedrespiratory apparattus becomes even less able to cope with thestress of exercise. It is as though a normal man went to anelevation of 15,000 feet, tightly bound his chest and abdomenin the position of quiet inspiration, and then proceeded to exercise.

The prognosis of these cases seems good for those with mildsymptoms, in that though they retain an abnormal roentgenogram,their symptoms (lo not tend to progress. Those having sev-eresymptoms tend to progress to a fatal outcome. Five of our caseshad relatively mild symptoms and are still living andl able to workat sedentary occupations. Eleven had severe symp)toms, and ofthese, six are dead, one is alive hut requires oxygen continuously,the remaining four are scarcely able to be even mildly active.

From the standpoint of diagnosis, these cases seem to fallinto a fairly well defined pattern. Careful clinical, roentgenologicand physiologic study will exclude most of the conflicting diag-noses. A history of exposure to the inhalation of beryllium com-pounds then categorizes the patient as belonging to the granulomaof beryllium workers. There is no question but that cases char-acteristic in every detail for pulmonary granulomatosis, lacking
