1.Plain Radiographic Findings of Lung Cancer with Delayed Diagnosis.
Journal of the Korean Radiological Society 1994;30(2):289-297
PURPOSE: In Korea, Lung cancer is the Second most common prevailing malignancy among male population next to stomach cancer. Although CT scan and MRI is widely used in the staging of lung cancer, plain chest x-ray still plays an important role in screening and diagnosis. Our intention was to review the confusing radiographic features which result in delayed diagnosis of lung cancer. MATERIALS AND METHODS: Of the 160 patients with lung cancer evaluated by us, 62 patients(39%) with delayed diagnosis had average diagnostic duration of 5.1 months compared with 2.1 months for those without delay. We reviewed the plain chest x-ray findings of those 62 patients. RESULTS: The diagnosis of lung cancer was delayed more than half of the cases under the impression of intrathoracic tuberculosis. Upon reviewing the roentgenologic findings in patients with diagnostic delay, central type appeared as a small hilar or mediastinal mass with or without obstructive pneumonia. Peripheral type appeared as an ill-defined pulmonary nodule, a nodule hidden by overlapping structures, or as a lung cancer associated with pulmonary tuberculosis. Some cases were misinterpreted as extranodal spread of malignancy. CONCLUSION: To solve above mentioned problems, we recommend proper understanding of natural history of lung cancer, incorporation of high kVp technique in chest radiographs, routine acquisition of lateral chest radiograph to increase diagnostic accuracy, and appropriate use of CT scan in cases of difficult diagnosis.

PURPOSE: Hypertrophic osteoarthropathy(HOA) is a clinical syndrome consisting of clubbing, periostitis and synovitis. Most frequent causes of hypertrophic osteoarthropathy are intrathoracic neoplasms, among which the bronchogenic carcinoma ranks the highest. But computed tomographic evaluation of intrathoracic neoplasm associated with HOA has been seldom reported. The purpose of this study is to evaluate CT findings of intrathoracic neoplasm associated with HOA, and to infer possible mechanism. MATERIALS AND METHODS: Seven cases of intrathoracic neoplasm associated with HOA were included in our study. Diagnoses of HOA were made by Tc99m bone scintigraphy or plain radiography. The findings of chest CT scans were reviewed retrospectively, with main interests on their size, location and internal characteristics, ect. RESULTS: Seven cases of intrathoracic neoplasm consisted of five bronchogenic carcinomas and two thymic tumors. The size of intrathoracic tumors were relativelY, large ranging from 6cm to 13cm(average 8.0cm). All thoracic neoplasms showed wide pleural contact, and one of them invaded thoracic wall. The range of length of pleural contact was 5-18cm(average 9.9cm). All of seven patients had internal necrosis, and one of them showed cavitation in thoracic mass. CONCLUSION: lntrathoracic neoplasms associated with HOA had a tendency to be large, to contain internal necrosis, and to widely abut the thoracic pleura.

Cryoglobulinernia occurs in about 5% of the cases of multiple myeloma. The most common finding in patient with cryoglobulinemia is ulceraticn that oceurs about ankle, hands, and occasionally the ears, upon prolonged exposue to cold. A 59-year old male had had 5 years of pain in his ears. There were black or dark brown colored ischemic ulcerations on his both helix. He also had mottled purpuric patches on his both ankles. A test for cryoglobulinema was positive. X-ray examination of the skull showed multiple punched but lesions. The bone marrow study revealed myeloma cell infiltration.

The authors studied the strabiEmus of 50 cases in children under six years of age. A total of 50 cases were screened in out patient department from April 1972 to July 1973. The results are as followings: Among them, 28 cases of exotropia, 18 cases of exotropia and 4 cases of hypertropia were observed. Generally, there were more female than male. According to the refractive status, there were more hypertropia among esotropia and more myopia among exotropia. There were only 3 cases those visual acuity were below 0.1 and the remainder were above 0.1. According to the age, there were 11 cases under the 2 yrs of age, 15 cases in the age 3 yrs to 4 yrs and 20 cases over 6 yrs. The onset of 36 cases were so incidious that were unknown and those of 8 cases were gradual. The strabismus were markedly detected under the 1 year of age (26 cases) and 31 cases were alternating type and 15 cases were monocular. And it \vas interesting fact that 19 cases were first child.

A 34-year-old female had an unusual case of cellular blue nevus which had behaved in a locally aggressive fashion. The lesion infiltrsted the adjacent soft tissue of left nail bed and extended into deep phalangeal bone. The involved left thumb was partially amputated because complete excision was impossible and we were quite concerned about malignant transformation. Histologically biphasic pattern without cellular atypism, a characteristic features of cellular blue nevus, was shown. About 2 years later, the lesion had not recurred.

Cutis verticis gyrata(CVG) is an unusual conformation of the scap characterized by the presence of folds and furrows due to thickening of the corium and the subutlneous tissue. In sccordance with etiological factor and associated findings, CVG occurs as primarary disease or secondary to a variety of local or systemic diseases. Cerebriform intradermal nevus(CIN) is a cause of CVG that can usually be recognized clinically and for a certainty histologically. We report two cases of CVG due to CIN. Not only did they have CVG due to CIN on the scalp, but also they had associated congenital nevi on the face and whole boispy, respectively.

Migratory birds have been suspected as playing a central role in transmission of various trematodes, but few surveys have been undertaken in the Republic of Korea. In the present study, we describe new fauna of microphallid flukes in Korea. Two species of microphallids were found in the intestines of 2 migratory bird species, namely the red necked stints (Calidris ruficollis) and the terek sandpiper (Xenus cinereus), in a coastal area of Gunsan-si, Jeollabuk-do. The microphallids recovered from the latter were 451 microm in length and 217 microm in width, and the eggs were very small, 13 microm by 8 microm. They had the characteristic extracecal vitellaria intruding into the median posttesticular area, belonging to Endocotyle incana. Another microphallids were discovered from both migratory birds, 417 microm in length and 249 microm in width. The cirrus was projecting into the genital atrium in form of male papilla, and bounded by a muscular flap, termed pseudogonotyl. They were identified as Spelotrema pseudogonotyla in consideration of the distinctive male papilla and pseudogonotyl. Besides these flukes, Maritrema obstipum and Gynaecotyla squatarolae also were recovered. This paper is in fact the first report on the presence of Spelotrema and Endocotyle in Korea.
