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.

Unilaterl frontal hyperhidrosis, a rare disorder of the sweat gland with localized hyperhidrosis, ia discribed. A 13-year-old female patient had increased sweating on the left half of the forehead, recurring in summer season for 2 years. Quantitative sweat collection demonstrated that the sweat glands responsive to those stimuli, which were thermal (direct and indirect heat), gustatory and cholinergic stimulation. A marked increase in sweat gland activity was noted on the affected areas as compared to the contaralateral normal sites, in thermal and gustatory effect. But, carbachol stimulation was not responsive. Biosy specimen which taken from the positive site of starch iodine technique showed increase number of sweat glands and ducts with somewhat dilated sweat ducts.

A case of electric cataracts in both eyes were presented. A 23 year old Korean Air-Forced soldier touched his right shoulder to a 22,900 volt, alternating current electric line on Feb. 15, 1972. He was unconcious for 25 hours and amnesic for 3 days. Also he sustained third or second degree burn on the neck, right hand and forearm, both lower extremities and superficial burns of the other body surface. Diminition of vision was first noted on April 15, 1972. When examined his vision on Aug. 14, 1972, the left eye was 20/100 and the right eye 20/30. And there were multiple fine scattered ant. subcapsular lens opacities in both eyes and left eye showed more numerous lens opacitities than right eye. By Dec. 27, 1972 there was a definite increase of the lens opacity in both eyes with marked post. subcapsular opacity and diffuse cortical hazy of the left eye. Vision was dropped to 20/70 in the right and hand movements in the left eye. For the left eye extracapsular lens extraction was done without any complication on Dec. 28, 1972. On July 10, 1973 the vision of the right eye was reduced to hand movements due to ant. and post. subcapsular opacities as well as cortical haze. On Sep. 27, 1973 extracapsular lens extraction was done. Vision was corrected as 20/20 in both eyes after operation and there were no complications.

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.

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.

Fibrofolliculoma is a benign follicular neoplasm which usually occurs in multiple and rarely solitarily. We have found only seven cases of previous reports of solitary fibrofolliculomas worldwide and only two in Korean literature. Herein we report on a 40-year-old female patient with a solitary flesh-colored bean sized mass on the scalp which histopathologically proved to be a fibrofolliculoma.
