A Case of Congenital Cystic Adenomatoid Malformation of the Lung / 대한내과학회지

Congenital cystic adenomatoid malformation(C.C. A.M.) is a rare variant of congenital pulmonary cystic diseases. C.C.A.M. was first distinguished from other pulmonary cystic lesions by Ch`in and Tang in 1949. It is characterized by cessation of bronchiolar maturation with an overgrowth of mesenchymal elements and proliferation of polypoid glandular tissue in the absence of normal alveolar differentiation. In 80% to 95% of cases, C.C.A.M. of the lung is confinded to a single lobe and there is no lobe predilection and right and left predominance. The clinical presentation may be widely variable, ranging from intrauterine fetal death secondary to nonimmune hydrops fetalis to discovery in childhood after recurrent pulmonary infections. Definitive treatment is removal of affected lobe. In rare instances, there is cases of myxosarcoma, embryonal rhabdomyosarcoma. Bronchoalveolar carcinoma arising in C.C.A.M.. So, resection is recommended even if they are asymtomatic. We have experienced a case of congenital cystic adenomatoid malformation (type II) of the lung in 15 year old man with pneumonia. After the improvement of pneumonia, surgical operation was performed. A brief review of the related literature is presented.

A case of single cervical tuberculous cold abscess associated with multi-loculated tuberculous pleurisy / 결핵

St. Francisco General Hospital, Seoul, Korea. Although the incidence of pulmonary tuberculosis is declining, the number of extrapulmonary tuberculosis has remained constant. Tuberculous Lymphadenitis accounts for over 50% of total inflammatory lymphadenitis and the most common site is cervical lymph node. We report a case of single cervical tuberculous cold abscess associated with multiloculated and septated tuberculous pleurisy. Intracavitary urokinase instillation via percutaneous catheter is indicated in loculated and septated pleural effusion. And our result was satisfactory without complication.

Nerepinephrine Secreting Pheochromocytoma in the Organ of Zuckerkandl With Epinephrine Granules in Cytoplasm / 대한내분비학회지

Extraadrenal pheochromocytomas developed from the paraganglia other than adrenal medulla are uncommon tumors. Such lesions have been reported that as much as 10% of retroperitoneal paragliomas arise outside the adrenal gland. But their incidence and prognosis are changing partly as a result of progression in developmental mechanism, diagnostic tools and concepts including ultrastructure, immunohistochemistry. The ultrastructure of chromaffine neoplasm from adrenal and extraadrenal tissues has been studied with chrarnaffine granule specificity and type of catecholamine content. With rare exceptions, extraadrenal chrornaffine tumor mainly has high concentration of norepinephrine which is suggested as dict relationship to numoruos electrone dense granular bodies in the cell cytoplasrn. High or intermediate level of epinephrine in tissue is associated with cytoplasmic granular bodies of much less density, Recently we experienced the exception, a case of norepinephrine secreting pheochrom-ocytoma in the organ of Zuckerkandl with epinephrine granules in cytoplasm and this discrepancy probably due to the plasticity

A case of mycoplasma pneumonia which progressed to ARDS / 결핵

Mycoplasma Pneumonia is a main cause of primary atypical pneumonia and may present in a variety of ways. One auther has stated that the infiltrate is of a lobar segmental type, while others have found the infiltrates to be mainly reticular or interstitial. We experienced a case of mycoplasama pneumonia, whic h progressed to ARDS pattern rapidly and recovered completely after ventilator care.
