Intussusception is a frequent cause of intestinal obstruction in early childhood and most are idiopathic in origin. In a minority of cases a definite pathological lead point is identified by imaging studying or during surgery. As the pathologic lead point of intussusception, Meckel's diverticulum is the most common lesion. In symptomatic patients, 40~60% of Meckel's diverticulum contain ectopic tissue, with gastric mucosa being far the most common type. A few Meckel's diverticulum contain pancreatic tissue. Combined heterotopic pancreatic and gastric tissues in the Meckel's diverticulum especially causing intussusception is extremely rare. We report the case of 5-year-old girl with an intussusception caused by Meckel's diverticulum containing both heterotopic gastric and pancreatic tissues.

Objectives: The aim of this study is to investigate the research trends of animal experiment on the herbal medicine treatment for endometriosis over the past 10 years. Methods: We searched the databases (Pubmed, Embase, Science-on) with terms as endometriosis, Korean medicine, herbal medicine and Chinese medicine. Among the results, we reviewed studies published from 2013 to 2022. Results: 26 studies were selected and analyzed. 8 single herbs and 18 complex formula were used in these studies. The most commonly used herbal medicine for endometriosis was Paeoniae Radix. Each studies showed that herbal medicine had significant effect on treating endometriosis. Conclusions: These results suggest that treating endometriosis with herbal material is effective in inhibiting ectopic lesion and angiogenesis, increasing pain threshold and apoptosis. Further research should be conducted to verify its therapeutic mechanisms and effectiveness.

A thymoma commonly occurs in the superior mediastinum or the upper part of the anterior mediastinum but can be located in other places in rare cases. Cystic degeneration in a thymoma is a relatively common but focal event. In rare cases, the process proceeds to the extent that most if not all of the lesion becomes cystic. We report a case of a patient with a paracardial cystic thymoma in the lower aspect of the anterior mediastinum. A 49-year-old woman was referred to our hospital because of a mass discovered incidentally on a chest X-ray. She showed no symptoms or signs. Contrast-enhanced chest CT scan revealed a $5{\times}5cm$ sized, well-marginated, right paracardial cystic mass with a curvilinear and oval enhancing solid portion. A Surgical resection was performed. The mass was discontinuous with normal thymic tissue. Microscopy revealed a type B1 thymoma with prominent foci of medullary differentiation according to the WHO classification. There was no capsular or local invasion. The postoperative course was uneventful and the patient was discharged in good health.

Purpose :This study was performed to determine the optimal treatment velum of Patients treating with radiation therapy for intracranial germ cell tumor. Materials and Methods : From 1993 to 1998, 19 patients with intracranial germ cell tumors treated by gamma knife radiosurgery were analyzed. The location of tumor was as follows; 9 cases on pineal region, 1 case on suprasellar region, and 9 cases of multiple lesion. 7 patients were pathologically verified; 5 cases of germ cell tumor and 2 cases of non germinomatous germ cell tumor. Tumor volume was ranged from 2.4 cm$^{3}$ to 74 cm$^{3}$. Irradiation dose was 10 Gy to 20 Gy with 50% isodose curve. Follow up period was 10 months to 54 months. Results : Recurrences were observed in 14 cases among 19 (74%) patients. Complete remission and partial remission were achieved in 2 (11%) and 10 (53%) respectively. No response was observed in 7 (36%). 2 cases were recurred within original tumor bed. 6 cases were recurred beyond but contiguous with tumor bed. Ventricular relapses separated from pretreatment tumor bed were 3. Spinal recurrences were 4. Among 8 recurred cases of which tumor volume is smaller than 20 cm$^{3}$, 2 were recurred within original tumor bed, 4 were recurred beyond but contiguous with tumor bed, and 1 spinal recurrence. Meanwhile, 6 cases of which tumor volume larger than 20 cm3, 1 case was recurred beyond but contiguous with tumorbed, 2 ventricular recurrences separated with original tumor bed, and 3 spinal recurrences. 5 cases which did not show any recurrence sign showed characteristics of single lesion, tumor volume smaller than 20 cm$^{3}$ and normal tumor marker. All of 4 cases of spinal recurrences happened in the case having ventricular invasion or lesion. Among 9 cases having multiple lesion, only 3 cases recurred within original tumor bed or around tumor bed, the other 6 cases recurred separated from pretreatment tumor bed. Conclusion : Gamma knife radiosurgery is not recommended for the treatment of intracranial germ cell tumor. It is because of small treatment volume and inadequate radiation dose that are characteristics of gamma knife radiosurgery. Tumor volume, ventricular invasion or ventricular lesion in multiple lesion are important factors to be considered for the wide field radiation therapy Tumor volume smaller than 20 cm$^{3}$, single lesion, no ventricular lesion or invasion, and normal tumor marker are ideal indications for small involved field radiation therapy. Prophylactic spinal irradiation seems to be necessary when there is ventricular lesion, ventricular invasion, and multiple lesions. When the tumor volume is larger than 20 cm$^{3}$, multiple lesions, abnormal tumor marker, and whole ventricular irradiation or partial brain irradiation would be possible and neoadjuvant chemotherapy would be most beneficial in these group.

A long-term follow-up study of a case of impacted teeth associated with a large dentigerous cyst in the left maxilla is presented. The patient was a 30-year-old man who had a large dentigerous cyst in the premaxilla and left posterior maxilla, which impacted the canine and supernumerary tooth. This is one of the most prevalent types of odontogenic cysts associated with an erupted or developing tooth, particularly the mandibular third molars. The other teeth commonly affected in order of frequency are the maxillary canines, maxillary third molars and rarely, the central incisor. Radiographically, the cyst appears as huge ovoid well-demarcated unilocular radiolucency with a sclerotic border and causes ectopic displacement of the inferior border of the maxillary sinus without destruction. Dentigerous cysts may grow unnoticed to such extensive sizes as to occupy a considerable portion of the maxillary sinus. These cysts appear to be associated with a supernumerary tooth in the maxillary anterior incisors region called the mesiodens and impacted canine. The present case report describes the surgical enucleation of a dentigerous cyst involving the permanent maxillary left canine and mesioden. After surgery, left maxillary sinus recovered their normal size and apposition of bone was observed around the apex of the posterior teeth. During the subsequent years, there was no recurrence of the cystic lesion but the inflammation was evoked in the anterior maxilla after 42 months. This complication appeared to have correlated with bony healing in the enucleation site of the cyst. We report the healing status of a huge dentigerous cyst in the maxilla for 5 years with a review of the relevant literature.

Endosalpingiosis is defined as the ectopic location of tubal epithelium. The term is purely descriptive and does not necessarily imply either the direct origin from tubal mucosa or the similarity of function. This study was performed to evaluate the clinical and pathologic characteristics of endosalpingiosis in the patients with endosalpingiosis proven by pathologic investigation. The medical histories and pathologic reports of 22 endosalpingiosis patients who received the laparotomy at Seoul National University Hospital from August, 1982 to December, 1990 were reviewed. The results were as follows: 1. Age distribution was from 26 to 46 years with the mean age of 34.0 years. 2. Twelve(54.6%) patients were nulligravida and the chief complaint of these patients was infertility(45.5%). 3. Six (27.3%) patients had the previous laparoscopic tubal sterilization by electrocautery or ring application. 4. Four (18.2%) patients had previous history of tubal pregnancy. 5. The most prevalent location of endosalpingiosis was the proximal segment of the salpinx, and the length of the proximal stump from the lesion was less than 1cm in 16(72.7%) patients.

Purpose: Sudoriferous cyst usually occurs on the face, and especially on the ear and scalp as a solitary cystic mass. It is derived from the sweat glands of Moll and results from the obstruction of excretory ducts with the retention of fluid. In the eyelid, it is usually seen as small and firm vesicle arising at the eyelid margin. If it rarely occurs on the orbit, it develops from orbital ectopic epithelial cells predetermined to form glands of Moll. We experienced a case of sudoriferous cyst on eyelid which was adhered to levator aponeurosis and it disappeared when patient closed eyes. Methods: A 55-year-old women suffered palpable mass on left upper eyelid without pain that had been present for 25 years. Orbital computed tomographic finding showed a oval mass($2.1{\times}0.6{\times}0.6cm$ size) inside upper eyelid and it invaded the orbit. The mass was completely excised under general anesthesia and histopathological examination was followed. Results: Cystic mass was purple color and it was located in superiorly to tarsal plate. The mass was adhered to levator aponeurosis and levator palpabrae superioris muscle between the fat layer of post-orbital septum and the Whitnall ligament. The mass was completely excised without injury of aponeurosis and muscle. Microscopically, the lesion was a solitary cyst lined by two layers of cuboidal epithelial cells and innermost cells displaying eosinophilic cytoplasm with apical expansions. Conclusion: Sudoriferous cyst usually occurs on eyelid margin. But in this case, cystic mass occurred on upper eyelid and disappeared when patient closed the eyes because it was partially adhered to levator aponeurosis and levator palpebrae superioris muscle. Therefore, if sudoriferous cyst occurs on eyelid, it is necessary to excised the mass carefully.

Cesarean scar pregnancy (CSP) is a rare complication that occurs in less than 1% of ectopic pregnancies, and uterine didelphys is one of the rarest uterine forms. We report a successful laparoscopic excision and repair of CSP in a woman with uterine didelphys and a double vagina. A 34-year-old gravida one, para one woman with a history of low transverse cesarean section presented to our hospital with a suspected CSP. She was confirmed to have uterine didelphys with a double vagina during an infertility examination 7 years earlier. Magnetic resonance imaging showed a 2.5-cm gestational sac-like cystic lesion in the lower segment of the right uterus at the cesarean scar. We decided to perform a laparoscopic approach after informing the patient of the surgical procedure. The lower segment of the previous cesarean site was excised with monopolar diathermy to minimize bleeding. We identified the gestational sac in the lower segment of the right uterus, which was evacuated using spoon forceps. The myometrium and serosa of the uterus were sutured layer-by-layer using synthetic absorbable sutures. No remnant gestational tissue was visible on follow-up ultrasonography one month after the surgery. This laparoscopic approach to CSP in a woman with uterine didelphys is an effective and safe method of treatment. In women with uterine anomalies, it is important to confirm the exact location of the gestational sac by preoperative imaging for successful surgery.

Odontogenic keratocyst is classified as a developmental odontogenic cyst and is believed to arise from cell rests of the dental lamina. It accounts for 3% to 11% of all jaw cysts and they occur twice as often in the mandible as in the maxilla. Histologically, the cysts are lined by stratified, keratinizing, squamous epithelium. Daugther cysts or microcysts are often observed microscopically. The recurrence rate has been reported variously, but is known by its high recurrence rate. These lesions are more common in males than in females, occur over a wide age range and are typically diagnosed during the 2nd and 3rd decade. The diagnosis depends on the cyst’s microscopic features and is independent of its location and radiographic appearances. This cyst is a radiolucent lesion that is often multiloculated, has a smooth or scalloped border. The cyst is characteristically located in the body and ramus of the mandible, and often occurs in conjunction with an impacted tooth. This case report describes an odontogenic keratocyst on the lower right molar area of an 8-year-old girl. The cyst was removed under the general anaesthesia, and is being checked regularly for any recurrences.

The eruption of permanent teeth represents the movement in the alveolar bone before appearance in oral cavity, to the occlusal plane after appearance in oral cavity, and additive movement after reaching th the occlusal plane. Tooth eruption is mostly controlled by genetic signals. The eruption stage is divided to preeruptive alveolar stage, alveolar bone stage, mucosal stage according to the process of growth and development. If the disturbance is occured in any stage of eruption, tooth does not erupt. The cause of eruption disturbance are ectopic position of the tooth germ, obstruction of the eruption path and defects in the follicle or PDL. In the treatment of eruption disturbance, surgical procedures are commonly used. There are three kind of surgical procedure ; surgical exposure, surgical repositioning, surgical exposure and traction Surgical exposure is basic procedure. This involves removal of mucosa, bone, lesion that are surrounding the teeth, dental sac when necessary to maintain a patent channel between the crown and the normal eruptive path into the oral cavity. To ensure this patency, many techniques including cementation of a celluloid crown, packing with gutta-percha or zinc oxide-eugenol, or a surgical pack, are used. When surgical exposure is conducted, operators should not expose any part of cervical root cement and not injure periodontium or root of adjunct tooth. After surgical exposure, tooth should be surrounded by keratinized gingiva. There is direct relationship between the extent of development of pathophysiologic aberrations and the intensity of the manipulative injury inflicted on the tooth by surgical treatment, so operator should consider this thing. In these cases, surgical exposure is conducted on Maxillary 1st milars that have a eruption disturbance and improve the eruption disturbance effectively.
