We have treated a case of pseudocyst of transverse mesocolon in 3-year-old male child. Operative findings demonstrated that the pseudocyst originated in the transverse mesocolon, and was not connected to the pancreas. A colonic duplication was found incidentally near the pseudocyst. On microscopic examination, ectopic pancreatic tissue was noted in the transverse mesocolon. This pseudocyst was thought to have originated from the ectopic pancreas of the transverse mesocolon. This is the first reported case of pseudocyst originated from ectopic pancreas of the transverse mesocolon, combined with a colonic duplication. The pathogenesis is discussed.

A 17 month-old girl presented in the pediatric clinic on November 27th, 1990 with a neck mass. The mass was 2 cm in diameter, firm in consistency and movable on the upper pole of the thyroid cartilage in the midline. The technetium thyroid scan showed a hot reactivity at the compatible site of the mass, but no other radioactivity in either site of the normal thyroid positions. At her second visit on January 23th, 1996, the mass had enlarged up to 3.5cm in diameter in the same location of the neck. The follow up thyroid scan revealed a walnut sized, snowman-like radioactivity. One of the snowman-like double images seemed to be a lingual ectopic thyroid and the other a midline ectopic thyroid remnant in the infrahyoid level. This interpretation was supported by the computed tomography of the neck, which showed a ligual mass in the foramen cecum area and an another mass in the anterior comis-sure of the larynx in the mildline. Thyroid function test was normal except a slightly increased TSH. As a result of this changing pattern of thyroid radioactive images, a case of a lingual thyroid as well as another midline ectopic thyroid tissue at the infrahyoid level is reported.

Hepatoid gland tumors in dogs usually occur in the perianal region, but arise occasionally from other areas such as the tail, back, and thigh. This report describes two cases of ectopic hepatoid gland adenomas in dogs. The tumors have been observed in the lumbar area of the back and in the axillary region, respectively. The cytological and histopathological features were consistent with hepatoid gland adenoma. Although ectopic hepatoid gland tumors have been described previously in literatures, this is the first report of ectopic hepatoid gland adenoma cases in dogs in South Korea.

An ectopic thyroid is caused by abnormalities in migration of the thyroid during development and rarely occurs in the thoracic cavity or the abdominal cavity. We report the case of a 64-year-old female who had abnormal findings from a thyroid hormone test during follow-up after thyroid cancer surgery. Based on the radioisotope diagnostic test, an ectopic thyroid inside the thoracic cavity was suspected. Through surgical treatment, the patient was diagnosed with ectopic intrapulmonary thyroid. Ectopic intrapulmonary thyroid is reported to be very rare and the case is described along with a literature review.

Ectopic cervical thymic tumor, first described in 1941 by Boman, is a rare tumor of the neck displaying the same histologic features as mediastinal thymoma. It was classified into benign thymoma, invasive (or malignant) thymoma, thymic carcinoma histopathologically and clinically. The ectopic cervical thymic tumor is misdianosed as the thyroidal mass on radiologic examination and FNA cytology due to its rarity and unusual location. Recently, we have experienced two cases of ectopic cervical thymic tumor misdiagnosed as thyroid mass ; a case of thymic carcinoma;the other of invasive thymoma. So, we report these cases with review of the literature.

The author observed a case of ectopic erupted maxillary second premolars and impacted mandibular second premolars due to premature loss of the primary second molars. The treatments were done as follows: 1. In the maxilla, the teeth arrangement problem was corrected with removal of the ectopic erupted second premolars. 2. In the mandible, normal dentition was established with surgical removal of the left second premolar and removal of the permanent first molar in right side combined by orthodontic therapy.

Impaction of third molar is a common developmental abnormality. However, ectopic impaction of the mandibular third molar in condylar region is an extremely rare condition. This report describes a case of impacted tooth in the mandibular condyle without any associated pathologic condition. Also, this report presents the spatial relationship of the impacted mandibular third molar to the surrounding anatomic structures using cone beam computed tomography.

This study reports a rare case of broad ligament abdominal ectopic pregnancy (EP). Interventions included preoperative transabdominal and transvaginal ultrasonography and operative laparoscopy. Successful extraction of the EP, followed by suturing of the mesosalpinx, was performed. Laparoscopic fertility-preservation treatment of broad ligament EP is valuable for women during the childbearing period.

Mandibular permanent lateral incisors showing bilateral transposition and ectopic eruption were seen beside deciduous first molars in a female aged 8yr 8month. Repositioning of the ectopic lateral incisor is difficult not only because of its distal displacement and severe rotation but also because of the potential development of transposition with the erupting canine. This paper is focused on the diagnosis of the ectopic eruption and advocates treatment with active orthodontic management at the early stage of mixed dentition, before the eruption of the permanent cuspid.

Ectopic eruption of the permanent first molar is defined as the eruption of the tooth in an abnormal position or orientation. It may causes distal root resorption and premature exfoliation of the adjacent primary second molar and uncontrolled space loss is followed. Prolonged partial impaction of the permanent molar may also cause undetected caries or abscess formation of the neighbor teeth. The purpose of this paper is to provide a brief review regarding the etiology, classification, and different management techniques for correcting ectopic eruption of permanent first molar.
