Cellulose acetate electrophoresis was used for differential diagnosis of radicular cysts and granulomas. Sixteen periapical lesions were excised from sixteen teeth with radiographic evidence of periapical pathosis, and two normal periodontal tissues were surgically removed from two wisdom teeth. The tissue samples were separated into two parts. Half was prepared for cellulose acetate electrophoresis, and the electrophoretic patterns were scanned with Helena densitometer. The other half was examined histologically, and the histologic diagnoses were then compared with the electrophoretic patterns and with the x-ray findings. The results were the following: 1. The histopathologic results showed the presence of 13 granulomas (81.8%) and 3 cysts (18.3%). 2. An albumin pattern, alpha-globulin pattern, beta-globulin pattern, fibrinogen pattern and gamma-globulin pattern were found in all eighteen cases. 3. All eighteen cases were divided into normal periodontal tissue group, dental granuloma group, and radicular cyst group by the histopathologic diagnosis. The electrophoretic pattern of dental granuloma group and that of normal periodontal tissue group resembled each other. The two groups showed the highest percentage in beta-globulin fraction, and the beta-globulin of dental granuloma group(47.17%) was higher than that of normal periodontal tissue group (40.54%) by 6.63%. On the contrary, beta-globulin fraction of radicular cyst group (28.00%) was much lower than those of the granuloma group (47.17%) and normal periodontal tissue group (40.54%), and alpha-globulin of radicular cyst group (34.16%) was much higher than those of the granuloma group (20.04%) and normal group (19.58%). 4. Five cases (31.3%) of the sixteen periodontal lesions showed different results between histopathologic diagnoses and radiographic findings.

Aneurysmal bone cyst is a benign lesion of bone consisting of a septated, cystic cavity filled with non-endothelium-lined, blood-filled spaces. As it grows, expanding and destroying the affected part of the bone by direct compression, the lesion characteristically produces a prominent bulging of the affected bone, which eventually erodes the overlying cortex. Patients rarely complain of pain unless the cyst affects adjacent nerves or its expasion is great enough to impinge on the surrounding joints and soft tissue. Teeth adjacent to the cyst may be displaced, but usually remain vital. Development of the lesion in the craniofacial region is rare, and the mandible is more often affected than the maxilla. Complete surgical excision is used to treat aneurysmal bone cyst, with either curettage or composite resection. This is a case report of 49 years old female with aneurysmal bone cyst treated with surgical excision & DFDB graft.

In a cattle which had died of extreme emaciation caused by cachexic condition, a huge cyst of $45{\times}35{\times}20$cm, in size was found at the rumen. The cyst having with the narrow stalk which ended in blind sac attached firmly to the rumen by fibrinous or fibrous adhesion and, contained the lightly yellowish, clear exudative fluid of about 20 l, in volume. Grossly, the thickness of the cyst wall was 10~14mm, and its inner portion of the half was very rigid and colored with milky white in contrast with soft and edematous outer portion of the half. Microscopically the inner portion of the cyst wall was consisted of scarred fibrous tissue and possessed at its inner margin a little amount of the muscle fibers which had degenerated passably. These were confirmed as the muscle fibers in specific staining property by Van-Gieson's and Mallory-Azan stain. On regarding to above findings of gross and microscopic pictures, it was considered to be a pseudo-diverticulous cyst composed of the serosa and the muscle layer deriving from the wall of the rumen. And it was suggested that the cyst had been growing up to big size by storage of the plenty exudate arisen from its wall and was separated from the rumen at the end of its stalk.

Baker's cyst is found as most frequent cystic mass around the knee occurring between medial head of gastrocnemius muscle and semimembranosus muscle. The proximal or posterolateral extension of the cyst had been rarely reported and the cyst into the surrounding muscular tissue extremely rare. Intramuscular Baker's cyst that we report was found between lateral head of gastrocnemius muscle and popliteus tendon, and then extended into the plantaris muscle. With review of the literature, we here report a very rare case of plantaris muscular extension of Baker's cyst.

This study was carried out to monitor the response of ovaries and cyst according to treatment with dinoprost or fenprostalene in dairy cows with ovarian luteal cyst. Twenty cows were diagnosed as luteal cysts by rectal palpation, ultrasonography and progesterone analysis. The cystic cows were treated with dinoprost or fenprostalene. All the animals were re-examined by ultrasonography and blood was collected for the measurement of plasma progesterone concentration at day 0 (the day of treatment), 3, 13 and 24, respectively. Mean plasma progesterone concentrations on day -11 and day -1 before treatment were 2.1$\pm$0.2 ng/ml and 2.8$\pm$0.3 ng/ml, respectively. On day 3 and day 13 were 0.3$\pm$0.1 ng/ml and 4.3$\pm$0.2 ng/ml, respectively. Mean cystic wall thickness on day -11 and day -1 were 3.2$\pm$0.2 mm and 3.9$\pm$0.2 mm, respectively. And on day 3 was 2.4$\pm$0.3 mm. The responses of luteal cyst after treatment noted during ultrasonography included dramatical degeneration of the luteal tissue of cystic wall on day 3 (all cows), slowly reduction of cyst size (cyst resolution) until last examination (8 cows), complete disappearance on day 13 (7 cows) and no changes of cyst size (5 cows). A group of 10 cows with luteal cysts injected fenprostalene compared with another 10 cows treated dinoprost showed a slightly higher pregnancy rate on first service after initial treatment (50.0 vs 30.0%). But treatment effects of dinoprost or fenprostalene did not significantly different results for each groups. This study suggested that the response of the cyst according to treatment revealed various types. Therefore, veterinarians should have attention on monitoring of the response of cystic ovaries after treatment, specially on no change of cyst size after treatment.

Neurenteric cysts are rare congenital lesions of the spine that are lined with endodermal epithelium. Their most common location is the cervico-dorsal region, and the mass usually lies ventral to the spinal cord. However the conus medullaris area location is an uncommon location. Neurenteric cysts are best treated by decompression and as near total excision of cyst membrane as possible. We report a case of a 7 year-old-girl with a neurenteric cyst in the conus medullaris. The patient had a history of meningitis and a gait disturbance. Magnetic resonance imaging [MRI] showed an intramedullary mass lesion in the conus medullaris with syringomyelia. There was no associated bone or soft-tissue anomaly. The mass was subtotally removed through a posterior approach. However 4 months later, meningeal irritation signs developed and MRI showed recurrence of the cyst. At the second operation, the cystic membrane was totally removed and the patient's neurological symptoms improved postoperatively. We reports a case of recurred neurenteric cyst occurred in unusual location with the review of literature.

Foregut cystic developmental malformations are rare developmental anomalies. It is important to diagnose the diseases and manage them properly because these cysts may generate feeding or respiratory difficulties depending on the size and location of the lesions. A newborn was referred for a congenital cervical swelling to our clinic on the second day of his life. Neck SONO and MRI showed an about 6cm sized cystic mass at left submandibular area. Aspirations and sclerotherapies were done repeatedly due to recurred cystic mass. Under the suspicious of cystic hygroma, the mass and submandibular gland were excised. Histologically, it was a benign cyst including gastrointestinal and bronchogenic mucosa and pancreatic tissue. Foregut cyst was suggested for the final diagnosis and the patient was discharged at 9 days after the operation without a complication. He has visited our out-patient department. Although several image studies have been introduced to find out foregut cyst, it is difficult to go through differential diagnosis because of similarity of other benign tumor. Further studies for early diagnosis of cervical foregut cyst are needed for preventing possible related problems.

Bronchogenic cysts are thought to be uncommon developmental anomalies. They develop from small buds or diverticuli that separate from the foregut in the formation of the tracheo-bronchial tree. They are nearly always located near the tracheal bifurcation; However, these lesions can occur anywhere along the tracheo-bronchial tree. We experienced a case of cervical bronchogenic cyst presenting sorely as an anterior neck mass in a 26-year-old woman. The neck ultrasonography showed as $1.4{\times}1.1cm$ sized hypoechoic lesion with a well-defined margin on the isthmic portion of the thyroid gland. Excision of the mass was carried out. The mass was superfical to the strap muscle and was contained within the subcutaneous tissue in the midline without any connection to the trachea. Grossly, the mass was an oval-shaped cystic lesion which measured 1.5 cm in the greatest diameter. The cyst was filled with thick, yellow, jelly-like material and the inner surface was smooth and glistening. Microscopically, the cyst showed a lining of ciliated columnar epithelium, beneath which was a loose areolar stroma containing plaques of mucous glands and mature cartilage. We thought this cervical bronchogenic cyst appeared to represent an expression of complete aberrent accessory lung bud detachment from the primitive foregut.

Meningioangiomatosis (MA) is a rare congenital tumor that occurs mostly in 5-15 year old children. There have been only 5 cases previously reported that described the cystic nature within these tumors. We present a case of a MA accompanied by a separate macrocyst. A normally developed 2 year-old female patient presented with partial and generalized seizures. The brain computerized tomogram and magnetic resonance imaging revealed the presence of a calcified mass accompanied by a cyst in the right parietal area, surrounded by low density and high attenuation edema and hemorrhage. Upon right parietal craniotomy, a $1.6cm{\times}1.2cm{\times}0.5cm$ sized plate-like, gray-white, slightly hard mass was seen and it was completely excised. Approximately 1 cm from the mass in the anterior lateral direction, a cyst was found and subsequent biopsy of the cyst wall revealed no tumor tissue, and therefore the cyst was not removed. Pathologic report demonstrated the meningioangiomatosis. Follow up examination 2 years later showed no recurrence of the tumor, and there was no evidence of neurological deficits. Authors suggest that cysts that arise in the surrounding tissues of tumors may not be tumor cysts, and do not require surgical removal.

The authors have interpreted one patient's full mJuth intra-oral films, oblique- lateral film of the left mandible and orthopantomograph which revealed 6 radicular and 1 residual cysts. As a results of interpretation of these serial films, we have drawn following conclusions: 1. Radicular cyst arose from the cell rests contained in an apical granuloma which was sequel to advanced pulpitis due to dental caries. 2. Residual cyst was developed from remaining cell rests after the extraction of a tooth with such a radicular cyst or apical dental granuloma. 3. Cyst grew in size by absorption of fluid into cystic cavity due to difference in osmotic pressure between the cystic fluid and adjacent tissue fluid.
