조혈모세포이식 후 1년 이내에 발생하는 폐 합병증의 진단 및 분류는 확립되어 있으나, 수 년 이상 장기간 생존자에게서 발생하는 폐 합병증에 대해서는 잘 알려져 있지 않다. 저자들은 8년 전 동종 조혈모세포이식을 시행받고, 호흡곤란을 주소로 내원한 18세 여자 환자에서, 폐조직 생검을 통해 비분류성 간질성 폐렴을 진단하였으나, 스테로이드 치료에도 불구하고 급격한 악화를 보여 호흡부전으로 사망한 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Erlotinib ($Tarceva^{(R)}$) has been considered to be a new, promising oral chemotherapy agent for local advanced or metastatic non-small cell lung cancer (NSCLC). Erlotinib is regarded as relatively safe, but interstitial lung disease (ILD) related to erlotinib has been reported on an infrequent basis in Asia. We report an histologically confirmed case of recurrent erlotinib-induced ILD. Although, the patient was highly responsive to the first erlotinib treatment, the therapy was discontinued due to erlotinib-induced ILD. After intravenous high dose methylpredinisolone treatment, ILD was improved rapidly by radiologic studies, but the particular lung cancer re-emerged. We restarted the patient erlotinib on low-dose oral methylpredinisolone, resulting in a recurrence of erlotinib-induced ILD. Our case suggests that re-administration of erlotinib should be performed on a limited basis in patients that have developed ILD on previous use, even if a therapeutic effect can be estimated.

Idiopathic pleuroparenchymal fibroelastosis (PPFE) is a rare, recently classified entity that consists of pleural and subjacent parenchymal fibrosis predominantly in the upper lungs. In an official American Thoracic Society/European Respiratory Society statement in 2013, this disease is introduced as a group of rare idiopathic interstitial pneumonias. We describe a case of a 76-year-old woman with cough and recurrent pneumothorax. She was admitted to our hospital with severe cough at first. High resolution computed tomography (HRCT) disclosed multifocal subpleural consolidations with reticular opacities in both lungs, primarily in the upper lobes, suggesting interstitial pneumonia. Rheumatoid lung was diagnosed initially through an elevated rheumatoid factor, HRCT and surgical biopsy at the right lower lobe. However, one month later, pneumothorax recurred. Surgical biopsy was performed at the right upper lobe at this time. The specimens revealed typical subpleural fibroelastosis. We report this as a first case of idiopathic PPFE in Korea after reviewing the symptoms, imaging and pathologic findings.

Pulmonary mucosa-associated lymphoid tissue-derived (MALT) lymphoma is a rare disease. This disorder is considered to be a model of antigen-driven lymphoma, which is driven either by autoantigens or by chronic inflammatory conditions. Low-grade B-cell MALT lymphoma may develop from a nonneoplastic pulmonary lymphoproliferative disorder, such as lymphocytic interstitial pneumonitis (LIP). A recent estimate predicts that less than 5% of LIP patients acquire malignant, low-grade, B-cell lymphoma. In Korea, there has been no previous report of malignant low-grade, B-cell lymphoma, acquired from LIP. Here, we present the case of a patient with LIP that developed into pulmonary MALT lymphoma, six years after diagnosis.

Valproic acid is one of the most common antiepileptic drugs used for the treatment of several seizure disorders. A 20-year-old man presented with a sudden decline of consciousness. He had a neurosurgery operation for intracranial and intraventricular hemorrhage. Following surgery, antiepileptic medication was administered to the patient in order to control his seizure events. On valproic acid treatment, he began to complain of fever and dyspnea. His symptoms persisted despite receiving empirical antibiotic treatment. All diagnostic tests for infectious causes were negative. A high-resolution computed tomography scan of the chest revealed predominantly dependent consolidation and ground-glass opacities in both lower lobes. The primary differential was drug associated with interstitial lung disease. Therefore, we discontinued valproic acid treatment and began methylprednisolone treatment. His symptoms and radiologic findings had significantly improved after receiving steroid therapy. We propose that clinicians should be made aware of the potential for valproic acid to induce lung injury.

High-Resolution thoracic CT (HRCT) is a scanning protocol in which thin slice thickness and sharpness algorithm are utilized to enhance image resolution for diagnosis and assessment of interstitial lung disease (ILD). This examination is sometimes performed in both supine and prone position to improve sensitivity to early changes of these conditions. Anatomical structures (the size of lung field and heart and descending aorta) of 150 patients who underwent HRCT were retrospectively compared. HRCT had been conducted in two positions (supine and prone). Data were divided into five groups according to patient body weights (from 40 to more than 80kg, 10kg intervals, 60 patients/each group). Quantitative analysis was utilized in Image J program. In the supine position defined as the control group, the average values of lung fields and heart size and aorta were compared with the prone position defined as the experimental group. The size of the lungs was found to be higher in the supine position, and it was confirmed that there was a statistically significant difference in patients over 70 kg (p<0.05). In addition, both sizes of the heart and descending aorta were larger in prone position, but in the case of the heart, there was no correlation with the presence or absence of ILD disease (p>0.05). Also, the area of prone in the descending aorta was higher than supine position, but there was no statistically significant difference between supine and prone position (p>0.05). In conclusion, when the severity of ILD disease was severe, there was no statistically significant difference in the area difference between supine and prone position, so it is considered that it will be helpful in diagnostic decision.

The introduction of high-resolution CT (HRCT) in recent years has improved the ability of radiologists to detect and characterize the diffuse infiltrative lung disease (DILD). The detection and diagnosis of diffuse lung disease using HRCT are based on the recognition of specific abnormal findings. In this article, pattern recognition of HRCT findings is reviewed in the differential diagnosis of diffuse infiltrative lung disease. In general, HRCT findings of lung disease can be classified into four categories based on their appearances. These categories consist of (1) nodules and nodular opacities, (2) linear and reticular opacities, (3) increased lung opacity, and (4) decreased lung opacity, including cystic lesions.

거대세포성 간질성 폐렴은 경금속 도구를 이용한 절삭, 연마공정에서 발생하는 경금속 분진을 흡입하여 발생하는 산업성 폐질환으로 알려져 있다. 저자들은 이러한 특징적인 경금속분진에 대한 노출력이 없이 발생하였던 거대세포성 간질성 폐렴을 수술적 폐생검과 폐조직내 금속 함유량 분석을 통해 진단하였기에 보고 하는 바이다.

To evaluate the impact of open lung biopsy on diagnosis and treatment of diffuse infiltrative lung disease, we conducted a retrospective review of 28 patients who underwent this procedure at the Kyoungpook National University Hospital from 1986 to 1993. There were 19 men and 9 women; average age was 50.9 years. During open lung biopsy, The region of the lobe was radiographically and grossly identified and was examined by a biopsy. The biopsy yielded a specific diagnosis in 27 [96.4 % patients and changes in therapy in 24[85.7% patients. Complications developed in three[10.8% patients, directly related to the biopsy procedure in 2. One patient died[3.6% due to underlying disease. We conclude that open lung biopsy can be accomplished safely in the patient with diffuse infiltrative lung disease and it is an important tool in decision-making process and therapy.
