To establish the differential diagnosis and functional status in ovarian cystic cows, progesterone(P$_4$) and estrogen(E$_2$) level of cystic follicular fluid, ultrasonography for measuring the cystic diameter and thickness of cystic wall, and histological findings were investigated in cystic ovaries from slaughtered Korean native cows. Ovarian follicles were classified as systic if the diameter was greater than 25 mm by ultrasonography. Ovarian cysts < 3 mm of cystic wall thickness, < 10 ng/ml P$_4$ concentration and >10 ng/ml E$_2$ concentration were classified follicular cyst, ovarian cysts 3 mm of cystic wall thickness, 10 ng/ml P$_4$ concentration and <10 ng/ml E$_2$ concentration were classified luteal cyst, and ovarian cysts 3 mm of cystic wall thickness, < 10 ng/ml P$_4$ concentration and <10 ng/ml E$_2$ concentration were classified non-functional ovarian cyst, respectively. Also ovarian cysts were classified 8 types by anatomical and hisctological findings. Ovarian cysts with corpus luteum were 3 of 73 cows and ovarian cysts without corpus luteum were 70 cows. The incidence rates of 8 various types of ovarian cysts were as follows; 2Aa 56.2%, 2Ba 20.5% and 2Ab 15.1%, respectively. The incidence rates of ovarian cysts without corpus luteum were follicular cyst 76.7% and luteal cyst 19.2%. The thickness of cystic wall were lAb 3.9 mm, 2Ab 3.3 mm and 2Bb 3.2 mm, and the cystic fluid P$_4$ concentrations were above 10.0 ng/ml in lAb, 2Ab and 2Bb, respectively. There was significantly correlations between the thickness of cystic wall and cystic fluid P$_4$ concentration in ovarian cysts(p<0.05). The ovarian cyst was classified follicular cysts, luteal cyst and non-functional ovarian cyst by hormone analysis. The luteal cyst was accuratly dignosed by cystic wall thickness. But follicular cysts was misdiagnosed 13 cows of 56 cystic cows. The 13 cystic cows was determined as had non-fuctional ovarian cysts. The cystic fluid P$_4$ concentration was 3.3 ng/ml in follicular ovarian cysts and 30.1 ng/ml luteinized ovarian cysts. There was significantly positive correlations between thickness of cystic wall and serum P$_4$ concentration in follicular(r$^2$ =0.59, p<0.001) and luteal cysts(r$^2$=0.65, p<0.001). These results indicated that ovarian cysts had various stages of degeneration and luteal cyst was accuratly diagnosed measurement of cystic wall thickness by ultrasonography, but follicular cysts was not diagnosed only cystic diameter and cystic wall thickness. In conclusion, it is suggest that ovarian cysts was diagnosed by combination of clinical sign and anatomical cystic features.

Cystic hygroma is a cystic tumor developed by lymphatic stasis due to congenital blockage of regional lymphatic drainage. It ususally occurs at neck and axilla. However, in some cases of cervical cystic hygroma, cervical portions of the cysts may extend into the mediastinum. We experienced a case of huge cervico-mediastinal cystic tumor in 11 month old girl presenting a large fluctuating neck mass and severe respiratory distress. Surgical resection was done through combined approach of cervical incision and median sternotomy. Pathological diagnosis was confirmed to cervico-mediastinal cystic hygroma.

Congenital cystic adenomatoid malformation[CCAM of the lung is extremely rare. We have experienced an unusual case of congenital cystic adenomatoid malformation. The patient was 20-year-old male and had chest pain for 10 days. On simple chest x-ray and Thoracic CT scan, there was a large cystic mass surrounded with multiloculated round cysts with air fluid level on the right lower lobe of a lung. Right lower lobectomy was performed and the pathologic result was congenital cystic adenomatoid malformation.

Cystic Meningiomas are rare tumor. There is a clear prevalance in infants, according for $10{\sim}19%$ of all intracranial meningiomas in this age group, compared with only $2{\sim}4%$ in adults. But, reports of cystic meningioma have been increased in frequency since the introduction of computed tomography[CT] and magnetic resonance image[MRI]. Authors report two cases of cystic meningioma in adults. Radiological finding showed extraaxial mass with cystic component. Authors performed total surgical resection of the tumor mass and of the entire cystic component with cystic wall in both patients. Postoperative histopathological diagnosis of the tumor mass was a transitional meningioma in both patients. Both patients showed favorable prognosis and no recurrence findings in follow up MRI.

Mature cystic teratoma is a common ovarian lesion, approximately 10-20% of ovarian tumor. However, it can undergo a malignant transformation, but incidence of malignant transformation is very low. Squamous cell carcinoma is the most common type of malignant transformation in the mature cystic teratoma. Preoperative diagnosis of malignant transformation in the mature cystic teratoma is very difficult, because malignant transformed tissues are very small in the mature cystic teratoma components. And so most of the carcinoma arising in mature cystic teratoma were diagnosed after histologic examination. We experienced a case of squamous cell carcinoma arising in the mature cystic teratoma of the ovary and report a case with a brief review of the literatures.

Objective: To determine the effects of respiration on the size of lung cysts by comparing inspiratory and expiratory high-resolution CT (HRCT) scans. Materials and Methods: The authors evaluated the size of cystic lesions, as seen on paired inspiratory and expiratory HRCT scans, in 54 patients with Langerhans cell histiocytosis (n = 3), pulmonary lymphangiomyomatosis (n = 4), confluent centrilobular emphysema (n = 9), paraseptal emphysema and bullae (n = 16), cystic bronchiectasis (n = 13), and honeycombing (n = 9). Using paired inspiratory and expiratory HRCT scans obtained at the corresponding anatomic level, a total of 270 cystic lesions were selected simultaneously on the basis of five lesions per lung disease. Changes in lung cyst size observed during respiration were assessed by two radiologists. In a limited number of cases (n = 11), pathologic specimens were obtained by open lung biopsy or lobectomy. Results: All cystic lesions in patients with Langerhans cell histiocytosis, lymphangiomyomatosis, cystic bronchiectasis, honeycombing, and confluent centrilobular emphysema became smaller on expiration, but in two cases of paraseptal emphysema and bullae there was no change. Conclusion: In cases in which expiratory CT scans indicate that cysts have become smaller, cystic lesions may communicate with the airways. To determine whether, for cysts and cystic lesions, this connection does in fact exist, paired inspiratory and expiratory HRCT scans are necessary.

A case of metastatic adenoid cystic carcinoma of the lung, originated from the trachea, was diagnosed by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with more common primary small cell neoplasms of the lung, i.e., small cell carcinoma, well differentiated adenocarcinoma, and carcinoid tumor of the lung. The features distinguishing adenoid cystic carcinoma from these neoplasms include 1) tight, globular, honeycomb pattern of cells, 2) acellualr basement membrane material in the lumen, and 3) cells lacking true nuclear melding and having bland chromatin pattern. The morphologic feature of metastatic adenoid cystic carcinoma in this case was so distinctive as to permit a definite diagnosis by aspiration cytology.

Purpose: Acid neutralization during chemical clearance is significantly prolonged in children with cystic fibrosis, compared to symptomatic children without cystic fibrosis. The absence of available reference values impeded identification of abnormal findings within individual patients with and without cystic fibrosis. The present study aimed to test the hypothesis that significantly more children with cystic fibrosis have acid neutralization durations during chemical clearance that fall outside the physiological range. Methods: Published reference value for acid neutralization duration during chemical clearance (determined using combined impedance/pH monitoring) was used to assess esophageal acid neutralization efficiency during chemical clearance in 16 children with cystic fibrosis (3 to < 18 years) and 16 age-matched children without cystic fibrosis. Results: Duration of acid neutralization during chemical clearance exceeded the upper end of the physiological range in 9 of 16 (56.3%) children with and in 3 of 16 (18.8%) children without cystic fibrosis (p=0.0412). The likelihood ratio for duration indicated that children with cystic fibrosis are 2.1-times more likely to have abnormal acid neutralization during chemical clearance, and children with abnormal acid neutralization during chemical clearance are 1.5-times more likely to have cystic fibrosis. Conclusion: Significantly more (but not all) children with cystic fibrosis have abnormally prolonged esophageal clearance of acid. Children with cystic fibrosis are more likely to have abnormal acid neutralization during chemical clearance. Additional studies involving larger sample sizes are needed to address the importance of genotype, esophageal motility, composition and volume of saliva, and gastric acidity on acid neutralization efficiency in cystic fibrosis children.

Splenic cystic lesion is uncommon in children, and cystic lymphangioma of the spleen has not been reported in Korean pediatric patients. Here we report a case of cystic lymphangioma arising from the spleen in a 16 year-old male. The patient presented with left flank pain for 5 days after blunt trauma to the same site. On physical examination, left abdominal tenderness and a palpable spleen were noted. Abdominal ultrasound and MRI revealed multiple septated macro-cystic mass abutting to the spleen medially, suggestive of cystic lymphangioma of the spleen. Laparotomy revealed a 20 cm sized cyst in the spleen, and 2,000mL of dark-brownish fluid was aspirated from the cyst. Splenectomy was performed. Pathological examination revealed the cystic lymphangioma. Post-operative recovery was uneventful, and the patient was discharged at 7 days after surgery.

Mature cystic teratomas, commonly called dermoid cysts, are the most common benign germ cell tumors of ovary in women of reproductive age. Mature cystic teratoma that constitutes 10-25% of ovarian tumors and 95% of teratoma, is germ cell tumor of the ovary. This occurs frequently in women less than 20 years old, but it can be found upto 10-20% in postmenopausal women. And in women over the age of 50, a mature cystic teratoma is likely to change into malignant form. Traditional surgical methods of mature cystic teratoma treatment include transabdominal cystectomy, oophorectomy, hysterectomy and(or) bilateral salphingooophorectomy. Recently laparoscopic approach replaces transabdominal surgeries in many cases. Vaginal removal of mature cystic teratoma is unique and rare. Compared with laparotomy, transvaginal approach is characterized by shorter hospital stay and lower morbidity rate. Compared with laparoscopic operation, transvaginal approach has advantages of no visible operative scar and lower intra-operative tumor spillage. The decision for surgical methods is related with patients' situations and surgeon's preference. We report 1 case of vaginal removal of mature cystic teratoma as a part of vaginal hysterectomy in old age patient.
