Bronchogenic cysts are uncommon congenital lesions which are derived from primitive foregut. Most of the bronchogenic cysts may occur at the tracheal bifurcation, both main bronchi, the lung parenchyme and the mediastinum. We experienced a case of bronchogenic cyst with a esophageal stalk. The diagnosis was made by simple chest x-ray and confirmed by bronchoscopy and chest CT. On the chest CT findings, 6.8X4.8 cm-sized oval shaped mass was located on the right posteroinferior side of the carina, elevating the right main bronchus and the thin wall of the mass was enhanced with contrast materials. On the operative findings, the esophagus and the cyst were connected with a stalk and the cyst was filled with mucinous materials. And on the histological findings, the mass was lined with pseudostratified ciliated columnar epithelium. Thus we report this case of bronchogenic cyst with review of literatures.

A 58-year-old woman presented with an incidental asymptomatic mass occupying the entire right lower thorax. A radiologic study demonstrated a huge cystic mass, initially suggestive of an exophytic echinococcal cyst. After unsuccessful catheter drainage, the patient was referred for surgery, and curative resection of the lung-, heart-, and diaphragm-compressing mass was performed under video-assisted thoracoscopic surgery. Culture studies revealed no growth of parasitic, bacterial, or fungal infections, and the final pathological result confirmed a primary pleural cyst. Thoracic cystic masses mostly manifest as bronchogenic or pericardial cysts, while primary pleural cysts have rarely been reported. We present a rare case of a huge pleural cyst that initially mimicked an echinococcal cyst.

Angiosarcoma is a rare but highly malignant tumorthat usually arises in the scalp or face of elderly males. Distant metastases favor the lung, liver, lymph nodes and skin. Metastatic pulmonary angiosarcoma commonly takes the form of a nodule but can sometimes appear as a thin-walled cyst. We report a case of 65 years-old male with a spontaneous pneumothorax, who underwent excision and radiotherapy for an angiosarcoma of the scalp 2 years ago. A chest CT scan revealed multiple cysts in the lung. The video-assisted thoracoscopic lung biopsy demonstrated subpleural cysts without tumor cells. A skin biopsy of the scalp showed an angiosarcoma. This case was diagnosed as a recurrence of an angiosarcoma with a supposed lung metastasis. This case suggests that a spontaneous pneumothorax in elderly people may be secondary to a pulmonary metastasis from an angiosarcoma of the scalp.

This is a report of 2 cases of human hydatidosis caused by Echinococcus ortleppi in Vietnam. The patients were a 12-year-old male (case 1) having a cyst of 10.0×9.0 cm size in the lung and a 50-year-old female with a 3.0×3.3 cm-sized cyst in the heart. Eosinophilia was 33.7% in the male and 45.8% in the female patient. C-reactive protein was increased to 16.5 mg/L in the male and 18.2 mg/L in the female. Both patients were positive for ELISA at OD=2.5 and 3.1, respectively. Echinococcus protoscolices were collected from the cysts by amniocentesis and surgery. The protoscolices were identified as E. ortleppi by morphology and analysis of mitochondrial NADH dehydrogenase 1 (nad1) gene sequence. Both patients were cured by surgical resection of the hydatid cyst combined with albendazole medication. The E. ortleppi infection in lung is the second report, and the other in the heart is the first in Vietnam.

Cystic intrathoracic lesions of foregut origin are now well recognized and account for approximately 10% of lesions presenting as mediastinal tumors. The terminology used to describe mediastinal endodermal cysts has been confused and sometimes ambiguous. The embryological derivation of these lesions has been the cause of much speculation. It Is suggested that these lesions should be classified Into three main categories based on embryology bronchogenic cyst[resulting from a defect of lung budding], Intramural esophageal cyst[true duplication], and enteric cyst[resulting from the split notochord syndrome]. This communication describes a 26 year old man with intramural esophageal cyst who was diagnosed as posterior medlastlnai tumor preoperatively and cured with extirpation of the cyst.

This is a case report of extralobar pulmonary sequestration with bronchogenic cyst located in aorto-pulmonary window area of left thorax in a 17 months old male patient. In this case, a bronchogenic cyst was presented immediately adjacent to the extralobar pulmonary sequestration. Communication between the extralobar pulmonary sequestration and bronchogenic cyst was not seen grossly or microscopically. The lesion was simply excised and the postoperatively course was uneventful.

Hydatid cystic disease of the lung is rare in Korea. Recently, the authors encountered 2 patients with this disease who were treated surgically with a successful outcome in both. The first patient, a 27 year old housewife never traveled outside Korea and the second, 25 year old man had a history of spending a year in Kuwait. These 2 cases are the first documented cases of pulmonary hydatoidosis among Koreans reported in the literature.

Congenital cystic adenomatoid malformation [CCAM] of the lung is a rare but often fatal congenital lung bud anomaly that causes acute respiratory distress in the newborn infants. In those who survive infancy and early childhood, its clinical manifestations are not unusual to detect. Recently we experienced two children with CCAM; one with coughing and high fever, another without any symptom On case I, the patient was a 9 year-old female, and was suffered from coughing and high fever since 15 days before. Medical treatment was failed and then, exploratory thoracotomy was performed under the impression of loculated empyema. Finally, a right lower lobectomy was done with a satisfactory postoperative course. On case II, the patient was a 12 year-old female, and admitted for evaluation of known large pulmonary cyst which was checked at the outpatient clinic. Preoperative evaluations gave no more informations, so obliteration of cysts was performed with open biopsy. Two patients with CCAM are described in Korean Univ. Medical Center.

It has been known that the pulmonary mycosis generally results from saphrophytic colonization of pre-existing lung cavities, e.g. , due to pulmonary tuberculosis, abscess, bronchiectasis. or congen-ital cysts. Recently, the authors experienced four cases of the pulmonary mycosis which were all treated surgically, and in our opinion, three of them were considered to arise from secondary saphrophytic colonization of pre-existing tuberculous cavities by serial chest roentgenograms. One of them was actinomycosis which was known as relatively rare pulmonary mycosis, and its clinical experience was previously reported. The purpose of this report is mainly to review our clinical experience and some related literatures with three patients with aspergillosis. Many writers have stressed the sputum culture for aspergillus, immunologic study and serial roentgenographic findings were all important or essential in diagnosing aspergillosis. Surgical resection appears to be the treatment of choice for the mycosis of lung, and systemic administration of effective anti-fungal agents such as amphotericin B for aspergillosis and penicillin for actinomycosis respectively following surgical intervention is usually necessary to eradicate completely.

Puimonary Langerhans cell histiocytosis is very rare, especially when accompanied by active pulmonary. tuberculosis. A patient was hospitalized due to excessive dyspnea and she was diagnosed with active pulmonary tuberculosis by a sputum AFB smear. The HRCT taken after hospitalization showed multiple micronodules and tiny cysts. An open lung biopsy confirmed the coexistence of pulmonary Langerhans cell histiocytosis.
