CONGENITAL CYSTIC DISEASE OF LUNG Cystic adenomatoid malformation or adenomatoid hamartoma of the lung has been reviewed. The case reported is that of a 3 pound 11 ounce premature Infant who had a successful left lower lobectomy at seven days of age. Although this Is a separate entity, there may be overlap with the other subclassifications of congenital cystic pulmonary disease! Newborn infants with this condition have severe respira-
tory distress. The roentgenogram Is diagnostic and must be done Immediately. Early removal of the tumor mass Is Imperative for these neonates may die withIn hours If untreated. HOLDER. T. M. AND CHRISTY. M. G.: "Cyst Adenomatoid Malformation of the Lung." J. Thor. and Cardioflas. SlIr8., 47:590. 1964.
RADIOLOGIC MANIFESTATIONS OF PULMONARY SARCOIDOSIS The author presents eIght well documented cases of pulmonary sarcoidosis which he classifies In the following four categories: (1) with a unilateral solitary filtrate (one case): (2) with dIscoid densities "confetti type" two cases: (3) with round densities, simulating metasta tic mallgnan t tumors (three
cases); (4) wi th necrotic Intrafocal cavities (two cases). He emphasizes the diftlculty In making the proper diagnosIs because of the lack of specific radiologic signs. A review of the llterature Is included. TURIAF,

USE OF ELECTRON MICROSCOPE IN THE STUDY OF BRONCHIAL CARCINOIDS The authors present a comparative study of the infrastructure of five benign. carcinoId bronchial tumors and one malIgnant digestive tumor. When osmotic acid Is used as a fixative. the usual findings are encountered but, when glutaraldehyde Is used intra-cytoplasmic granules of secretion are found.
There are a number of Interesting photomicrographs Included. VERLEY, J. M. AND KOURILSKY, R.: "Etude au Microscope Electronique des Tumeurs Carcinoides des Bronches.'· J. Fran. de Med. el de Chir. Thor., 29:37. 1965.
COLLEGE FELLOWSHIP PROGRAM The American ColI e g e 0 f Chest Physicians is offering three fellowships, as indicated below: Eudowood Fellowship for Tuberculosis \vith a grant of $2,500.00 per year for postgraduate training in the United States in tuberculosis. Candidates must hold the ECFMG certificate. Li S h u-F an Fellows hip for Postgraduate Study in Chest Disease appropriates $1,000.00 annually for a twelve month period of training in any country. If the postgraduate training is taken in the United States, the ECFMG certificate would be required.
Alfred A. Richman Fellowship for Chest Disease offers $100.00 a month for a period of
one year's postgraduate study in any country. Candidates must hold the ECFMG certificate if training in the United States. Physicians in terested in the above fellowships should contact Dr. Andrew L. Banyai, Chairman of the Council on International Affairs, at the Executive Offices of the American College of Chest Physicians, 112 East Chestnut Street, Chicago, Illinois 60611 , U.S.A., for application forms.
