Cutaneous metastases from internal malignancy are relatively rare. Three cases of cutaneous metastases, two from lung cancer and one from breast cancer are reported. Case 1-cutaneous metastasis from bronchioloalveolar carcinoma of the lung, where four erythematous to pinkish pea sized smooth surfaced nodules on the scalp were noticed for 2 years in a 48-year-old man. Case 2-cutaneous metastasis from adenocarcmoma of the lung, where two hard tender freely movable subcutaneous nodules, about 3 cm in diameter on the lateral chest wall were noticed for 6 months in a 61-year-old woman. Case 3-cutaneous metastasis from infiltrating ductal carcinoma of the right breast, where a hand, violaceous, non-tender plaque (8×6.5 cm) on the right areolar area was noticed for 4 months in a 47-year-old woman.

Leser-Trelat sign is characterized by the sudden appearance and rapid increase in number and size of seborrheic keratoses associated with an internal malignancy. A 78-year-old woman showed multiple pea to bean sized dark brownish papules and plsques on the trunk. Skin lesions had appeared suddenly since 5 months ago and then rapidly increased in number and size. The histopathologic exsmination of the skin lesions revealed seborrheic keratoses. The chest roentgenogram revealed the mass shadow on the right hilar region and transbronchial lung biopsy revealed small cell carcinoma.

BACKGROUND: Serum eosinophil cationic protein(ECP) level has been proposed as a indirect marker of eosinophilic inflammation of the airway in bronchial asthma. OBJECTIVE: To evaluate serum ECP against indirect clinical markers of disease, we compared bronchial obstruction, bronchial hyperresponsiveness and peripheral blood eosinophil counts, total IgE with serum ECP levels in patients with bronchial asthma and normal controls. METHOD: Fourty-two patients with bronchial asthma and twenty-six normal controls were enrolled. Measurement were made by spirometry, inhalation challenge with methacholine, peripheral blood eosinophil counts, total IgE and FEIA(fluoroenzymatic immunoassay) of serum ECP RESULT: Serum ECP levels were significantly higher in asthmatic patients than normal controls(p<0.0,5). Serum ECP levels were correlated with peripheral blood eosinophil counts(p<0.01, r=0.544) and bronchial hyperresponsiveness(PC,)(p<0.01, r=-0.456) in patients with bronchial asthma. Serum ECP levels were correlated with degree of bronchial obstruction(FEV, % to predicted value, FEV1/FVC%) in total subjects, but not in asthmatic patients. CONCLUSION: Serum ECP level may be used as indicator of disease activity in bronchial asthma and be helpful in differentiation between normal person and asthmatic patients on simple serological method. Further studies on the changes of serum ECP levels according to disease course and therapeutic responses are needed.

BACKGROUND: To evaluate airway responses and inflammation to antigen in Sprague-Dawley rat asthma model, we examined airway responses, serial histologic changes of the lung, and the relationship between airway responses and airway inflammation after antigen airway challenge. METHODS: Sprague-Dawley rats were sensitized with subcutaneous injection of 10 microgram ovalbumin(OA). Antigen airway challenges were done 14 ~16 days after sensitization and the sensitized rats were sacrificed 1h(AE), 6 ~8h(AL) and 1day(AD) after airway challenge, to examine the histologic changes of the lung. Airway responses were measured by body plethysmograph and recorded by enhanced pause(Penh) as an index of airway obstruction 6 ~8h after antigen challenges. Nonsensitized controls(10 rats) were also challenged with antigen and sacrificed 1 day later. Histopathologic examination of two trachea, large bronchi, small bronchi, and vessels was performed to evaluate the severity of inflammation and eosinophilic infiltration with H&E stain. RESULTS: In 17 of 20 rats(85%) in both groups, we observed airway responses. Among them, an early response(ER) in 15 rats(75%), an dual response in 5(25%), and an late response(LR) only in 2 rats(10%) displayed. There were no significant differences in the severity of inflammation among the trachea, large bronchi, small bronchi and vessels in all groups after antigen challenge(p>0.05) and between early and late responders. The significant eosinophil infiltration was observed in 5 rats(50%) of AL(p<0.05) compared with in AE and controls. Also, eosinophil infiltration was observed in higher trend in LR(57.1%) compared to ER(40%)(p>0.05). CONCLUSION: Sprague-Dawley rats sensitized with subcutaneous injection of OA showed a significant airway responses to antigen challenge. But antigen challenges caused a little eosinophil infiltration and no significant airway inflammation. Asthma model of Sprague-Dawley rats could be useful for antigen-induced airway responses, but this model has a limitation for the study of human asthma because of no significant pathologic change.

Bronchial asthma is a chronic airway inflammation disorder involving lymphocyte activation and various cytokines secretion by lymphocyte. The inflammatory response results from a complex network of interactions between inflammatory cells (mast cells, eosinophils, macrophages) and resident cells belonging to the lung structure itself like EC, fibroblasts, or bronchial epithelial cells. IL-6 which is known to up-regulate the endothelial cell expression of adhesion molecules participating in the development of the inflammatory reaction in bronchial asthma is produced by alveolar macrophage. ICAM-1 is produced by bronchial epithelial cell and expression by endothelial cell, which is known to enhance of the influx of various cells. RANTES which is known to a potent chemoattractant for eosinophils, lymphocytes, and monocytes, a member of the CC chemokine family, is expressed by bronchial epithelial cell. To evaluate whether markers of lymphocyte activation are useful markers of disease activity in bronchial asthma, we measured sIL-6, sICAM-1, sRANTES in 42 patients with mild to moderate bronchial asthma and in 26 normal controls and compared the result with other disease activity markers in asthma (pulmonary function, blood eosinophil counts). The mean level of sIL-6 was higher than that of normal control and correlated significantly with sICAM-1, FEV1% to predicted value. The mean level of sICAM-1 was higher than that of normal control and correlated significantly with FEV1%, FEV1% to predicted value. The mean level of sRANTES showed the tendency to be higher than that of normal control, but not significant statistically, and did not correlated with sIL-6, sICAM-1, FEV1%, FEV1% to predicted value, blood eosinophil counts. It appeared that sIL-6 and sICAM-1 could be a disease marker in bronchial asthma. But, clinical application of the measurement of these markers needs to be studied further.

PURPOSE: To evaluate changes in tuberculous cavities, one of the major factors used to determine the activityof tubereulosis, by high-resolution CT(HRCT) in active pulmonary tuberculosis patients after antituberculoustherapy. MATERIALS AND METHODS: The HRCT findings of 41 patients with active tuberculosis were analyzed withparticular emphasis on the appearance of tuberculous cavities before and after therapy. We measured the largestdiameter and maximal wall thickness of the cavities, as well as accompanying changes occurring during follow-up.The mean interval between initial and follow-up study was 8.7 months(minimum:4.1, maximum:33.2;S.D.: +/-5.0) andthe mean duration of antituberculous therapy was 7.5 months(minimum:4.7, maximum:14.8;S.D.: RESULTS: Among 41patients, 54 cavities were found on initial HRCT. Thirty one(57.4%) of these disappeared during follow up HRCTwith residual changes such as residual fibrotic scar(n=15), granuloma(10), paracicatrical emphysema(7),calcification(3), traction bronchiectasis(3), consolidation(3) and bullous emphysema(1). Twenty three of thecavities(42.6%) decreased in size and wall thickness, but did not disappear completely during follow-upexamination. Mean largest diameter and maximal thickness of 23 cavities were 32.0mm(+/-13.9) and 7.9mm(+/-4.8) oninitial HRCT, falling to 20.9mm(+/-12.5) and 4.1mm(+/-2.6), respectively, during follow-up HRCT. Among four patientswho underwent a second follow-up, the largest diameter and maximal thickness of the cavities decreasedcontinuously. In two patients, however, the cavities did not did not disappeas, though in the other two they haddisappeared by the time follow-up HRCT was performed a second time. CONCLUSION: During follow-up HRCT afterantituberculous therapy(mean duration of 7.5 months), 57.4%(31/54) of cavities were seen to have disappeared, withresidual changes such as fibrotic scars, granulomas, paracicatrical emphysema and calcification ; 42.6% of thecavitivies still remained, however, with retractive and fibrotic change. Such fibrotic and retractive changesshould not, therefore, be taken as indicative of active tuberculosis, especially in patients who have successfullycompleted their medication.

Kartagener's syndrome is an autosomal recessively inherited condition characterized by triad of situs inversus, bronchiectasis, and chronic sinusitis. And recently it was classified as a subclass of dyskinetic cilia syndrome, which has a defect in mucociliary transport resulting from immotile or dyskinetic beating of cilia. Electron microscopic examination of the cilia from sperm tails, nasal and bronchial epithelium of patients reveals the partial or the complete absence of dynein arms or radial spoke, or microtubule disposition. This patient had all the triad of Kartagener's syndrome and showed two extracentral microtubules on the electron microscopic examination of the nasal mucosa. Most patients have dynein arms defect, but it is rare to have extracentral microtubules. So we report one case of Kartagener's syndrome with extracentral microtubules confirmed by electron microscopy.

BACKGROUND: The routine application of the combined regimen of corticosteroid-antituberculosis therapy to the tuberculous pleurisy remains controversial. Steroid therapy to tuberculous pleurisy could be effective on the acceleration of absorption of pleural effusion and symptom improvement, but there has been debate about the effect of prednisolone on the prevention of pleural adhesion. So we studied the efficacy of combined regimen of prednisolone-antituberculosis therapy on the absorption of pleural effusion and prevention of pleural adhesion. METHODS: A prospective, randomized study was performed in 82 patients, 50 patients(non-steroid group) were treated with only antituberculosis regimen for 6 months and in 32 patients(steroid group) prednisolone(30mg/day) were administered in addition to antituberculosis regimen for one months and tapered for another month. The amount of pleural effusion was compared at the beginning of treatment, 2nd month, 6th month and final visit with chest X-ray findings which were graded from grade 0(complete absorption) to grade 6(near total haziness). RESULTS: The amount of pleural effusion of steroid group at 2nd month, 6th month and final visit was lesser than that of non-steroid group (P<0.05). The incidence of the complete absorption of the pleural effusion was 3/32(9.4%) in steroid group, 1/50(2%) in non-steroid group at 2nd month after treatment; and 12/32(37.5%) in steroid group, 6/50(12%) in non-steroid group at 6th month after treatment (P<0.05). At final observation, the incidence of residual pleural thickening was 15/32(47%) in steroid group and 37/50(74%) in non-steroid group (P<0.05). No serious side effects were noted during the treatment with prednis olone. CONCLUSION: The administration of prednisolone in conjunction with antituberculosis chemotherapy improved the absorption of pleural effusion and decreased the residual pleural thickening.
