Sarcoidosis, a multisystemic granulomatous disorder of unknown causes, which presents with bilateral hilar adenopathy, pulmonary infiltration, and cutaneous, ocular, bones, and nervous and reticuloendothelial systems involvement, commonly involves young adults of both sexes. Herein, the case of a 70-year-old male, with progressive hoarseness of two weeks' duration and mild dyspnea, is reported. A fiberoptic bronchoscopy, performed to investigate the hoarseness, revealed paralysis of the left vocal cord, but with no other local abnormality. Two nodules, as pathologic findings, showed noncaseating epithelioid cell granulomas. We note a rare case of sarcoidosis, with vocal cord palsy, in Korea.

The incidence of pulmonary thromboembolism increases with age. The risk factors of pulmonary thromboembolism include surgery, malignancy, obesity, lupus anticoagulants, and vascular conditions such as deep vein thrombosis. Thromboembolism in younger patients or in unusual locations, the possibility of primary thrombophilic conditions should be considered. Primary thrombophilic states include myeloproliferative disorders (MPD). JAK2 V617F mutation is found commonly in patients diagnosed with MPD, in 90~95% of polycythemia vera (PV) and in 50~60% of essential thrombocytosis (ET) patients. Sometimes the JAK2 V617F mutation is found in cases without MPD. The relationship between JAK2 V617F mutation and thrombosis has not been defined. Recently, clinical evidence suggests that this mutation may be variably associated with thrombosis. We present one case of pulmonary thromboembolism in a young patient, who was positive for the JAK2 V617F mutation and did not have MPD.

Eosinophilic granuloma (histiocytosis $\times$) is an uncommon granulomatous disorder affecting the mononuclear phagocytic cell system caused by unknown etiology. When confined to the lungs, it is also known as pulmonary eosinophilic granuloma or pulmonary histiocytosis $\times$. After the first case was described in 1951 by Farinacci et ai, more 250 cases were reported in the English literature. However only 4 cases has been introduced in our country. We describe two additional cases. In both cases, open lung biopsies are performed for definite diagnosis and examined by immunohistochemical stain for S-100 protein and electron microscopy for ultrastructural identification of Birbeck granule.

Idiopathic hypereosinophilic syndrome (HES) is a disorder characterized by prolonged eosinophilia without an identifiable cause and eosinophil related tissue damage in multiple organs including heart, lung, skin, gastrointestinal tract, liver, and the nervous systems. Pulmonary involvement occurs in about 40% of HES cases, but pleural effusion due to pleuritis and bilateral pneumothoraces are very rare manifestations. We report a case of hypereosinophilic syndrome presented with bilateral pleural effusions and recurrent bilateral pneumothoraces in a 44 year-old male with brief review of the literature.

Periodic hemoptysis occurring at the time of menstruation (catamenial hemoptysis) is a rare disorder and generally signifies indicates the presence of thoracic endometriosis. A diagnosis of catamenial hemoptysis is usually established based on the clinical history and the exlusion of other causes of the recurrent hemoptysis. Serial computed tomograms of the chest during and in the interval between menstruations periods is a useful confirmatory test. We report the case of a 22 year-old women who suffered from catamenial hemoptysis for 10 months and was treated successfully with a wedge resection of the lesion by video-assisted thoracoscopic surgery(VATS). There was no evidence of recurrence. In conclusion. VATS is a good choice as a for single focus for catamenial hemoptysis.

Paraneoplastic neurologic syndrome is a group of assorted disorders resulting from damage to the nervous system in cancer, remote from primary site, and not related to metastasis, infection, or metabolic disorder associated with cancer. Patient with small cell lung cancer sometimes shows various neurological syndromes, but patient with non-small cell lung cancer rarely shows neurologic syndromes and few antineuronal antibodies have been found. Here, we report a case of 53-year-old male patient who developed ptosis and extraocular muscular limitation of left eye due to third and forth cranial nerve palsy in non-small cell lung cancer without brain metastasis. These neurologic symptoms improved after lobectomy without any other treatment immunotherapy.

Hemolytic uremic syndrome (HUS) is a rare disorder characterized by the triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure. HUS arises from a wide spectrum of conditions, and chemotherapeutic agents have been reported to be associated with HUS, including Mitomycin, Cisplatin, Bleomycin, and Gemcitabine. A 76-year-old man treated with Gemcitabine due to non-small cell lung cancer developed clinical and laboratory findings compatible with HUS. Gemcitabine was ceased and hemodialysis and plasma exchange were utilized and he recovered. A high level of suspicion for HUS is necessary when cancer patients are treated with Gemcitabine, and prompt recognition and treatment are also essential.

Idiopathic pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by surfactant component accumulation in the alveolar space. Idiopathic PAP has recently been recognized as a autoimmune disease of impaired alveolar macrophage function caused by autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF). While whole lung lavage has been the standard treatment, not every patient shows a complete response. Subcutaneous injection or inhalation of GM-CSF is another promising treatment option for PAP. A 45-year-old patient visited our hospital for dyspnea, he was diagnosed as PAP and underwent whole lung lavage. Eighteen months later, the patient had not achieved complete remission in despite of initial response. After then he was administered with GM-CSF (5 ${mu}g/kg/day$, subcutaneous injection) for fivetimes a week during 2 months. Nine months later, the abnormal shadows in high-resolution computed tomography (HRCT) decreased and the patient fully recovered in forced vital capacity. After 60 months, the HRCT scan showed complete remission of PAP.

Pulmonary arteriovenous fistula is a congenital vascular malformation in lung resulting from abnormal capillary development and the exact etiology is not well known but it may occur with or without hereditary hemorrhagic telangiectasia. Hereditary hemorrhagic telangiectasia (HHT) or Rendu-osler-Weber disease is an autosomal dominant vascular disorder which associates epistaxis, mucocutaneous and visceral telangicetases, and recurrent hemorrhage with chronic anemia and visceral shuntings. Recently we experienced a case of the pulmonary arteriovenous fistula in a 23 year-old woman with a family history of this disease, which was confirmed by pulmonary angiography.

Acute transverse myelitis is a focal inflammatory disorder of the spinal cord, resulting in motor, sensory, and autonomic dysfunction which would be the initial manifestation of acute disseminated encephalomyelitis. A 7-year-old boy developed weakness of lower extremities associated with dizziness and urinary dysfunction after upper respiratory infection. He showed gradual decreased mental status with respiratory difficulty. Spinal MRI showed diffuse spinal cord swelling from C3 to C7 levels with high signal intensity lesion on T2-weighted image, which is involved central gray matter of spinal cord from C3 to C7, proximal portion to cervicomedullary junction, and distal portion to the cornus medullaris. After the supplement of high dose intravenous methylprednisolone therapy with ventilator care, he showed gradual improvement. The brain MRI after extubation showed multifocal high signal intensity lesions in bilateral cerebral white matter on axial T2-weighted image. Immunoserologic test(neutral antibody test) for enterovirus 71 was positive. Dysfunction of the bladder lasted for 33 days. We report a case of transverse myelitis which progressed to acute disseminated encephalomyelitis by enterovirus 71 in a 7-year-old boy with related literatures.
