I am custodian of the original archives of Dr. Arthur J. Vorwald. Pages 1 through 3 attached hereto are true, correct and authentic copies of documents from Dr. Arthur Vorwald's archives. The pages attached are rr P -/ Dr. Vorwald was the Director of the Saranac Laboratory of the Trudeau Institute. Upon his death. Dr. Vorwald's archives were donated to the Armed Forces Institute of Pathology by his widow. RHOD.AFF - Page 1 of 2 Dr. Vorwald's archives are in such condition as to raise no suspicion concerning their authenticity? they were received by the Armed Forces Institute of Pathology from Dr. Vorwald's widow after Dr. Vorwald's death? they are presently on file as authorized by law in the National Museum of Health & Medicine, Armed Forces Institute of Pathology, Building 54, Walter Heed Army Medical Center, Washington, D.C. 20306-6000? and the archives have been in existence for 20 (twenty) or more years. SWORN TO AND SUBSCRIBED before me, the undersigned Notary Public, on this the day of , 1995. My Commission Expires: NOTARY PUBLIC RH0D.AFF - Page 2 of 2 Case 129 S-35-86 4/^ ?*** . i rry ..ber* sor. /W. -4^-5 A-' Dr Leary Age: 42 The right and the left lun^s show chronic fibrous adhesions on the pleura of the upper lobe* Through the ".enerally thickened and opaque pleura can be seen snail clusters of grey to yellowish ill-defined nodular areas* Section discloses a linear fibrosis of the peripheral 5 cm below the sub-pleural tissue involving generally the whole circumference of the lung* This is composed of strands of fibrous tissue containing small foci of pigmentation. There' is no evidence of active infection. In the fibrous tissue immediately beneath the pleura,but not elsewhere, are numerous small round cavities not over 2 ran* in diameter* These have smooth, glistening internal walls and contain no fluid* They may be dilated air spaces* Elsewhere the lungs show some dilatation of the air spaces and some general thickening of the alveolar septa. There la early fibrous pleurisy of the left base*. TRACHEOBRONCHIAL LYMPH NODES - are large, generally firm, yellow In color but streaked with black* No focal tubercles are dis closed* *t one point the node presents a series of thin-walled holes all less than 1 mm* in diameter* In the mediastinal fat and connective tissue there are large thin-walled spaces apparently of emphysematous origin* Anatomical Diagnosia Simple asbestosis without evidence of infection* Microscopic Examination LUNGS - show uncomplicated asbestosis with lesions in an unusual distribution. There is extensive fibrosis largely involving the subpleural region of the lung and the Interlobular septa* Some of the finer Interalveolar septa are fibrous but the strands are very thin* The L*-.. vascular and bronchial trunks are not much thickened* The fibrous tissue la generally coarse and wlrey, obliterating moat of the normal structures where it has developed* ~Xn places there are ill-defined .focal collect toms of black particulate matter that probably gave rise to te nodule-like foe! noted in gross* Asbestosis bodies are not particularly numerous in V.v these areas but they are thickly scattered,throughout all fibrous areas. The fibres generally run in an extremely Irregular network* Sometimes they are thick and swollen, but more often they are thin and clear cut* Beneath the pleura the fibrosis is well supplied with Isrge thinwalled blood vessels* The minute cavities described in gross are due to emphysematous dilatations of small bronchioles lined by columnar nonclllated epithelium* These structures have been pulled outward by con traction of the subpleural scar tissue. Gland-like cross sections are found throughout the scar* The contraction has also caused the develop ment of marked distortion of the smaller underlying air spaces* The interlobular aepta are very heavy due to the deposition of dense, non-cellular, connective tissue about them. They also contain asbestosis bodies* The air spaces are empty, often dilated and Case 129 page 2 separated by thin but fibrous septa. There is little or no involve ment of the air spaces in the centre of the lung and the usual peri bronchiolar collars of fibrosis are lacking, unless it occurred only in the subpleural portions of the lung and was subsequently obliterated. The lymphoid tissues on the trunks are not involved. There is no evidence of infection. TRACHEOBRONCHIAL LYMPH NODES - contain rather large deposits of brown-black granular pigment but no asbestosis bodies. There is no reaction about this pigment and evidence of infection is wanting.
