The author has experienced a case of microphthalmos with large orbital cyst in a 4 months old female, that was found at the time of birth. To facilitate fitting a cosmetic prosthesis, the microphthalmos with cyst was removed surgically. On serial section I could find an area of discontinuation of the sclera that was suspected to be the defective closure of the embryonic cleft. Some aberrant retinal tissue was found in the wall of the cyst, and markedly disorganized ocular tissue forming a tumor-like mass filled the microphthalmic eyeball. In view of these histopathologic findings I could draw the conclusion that developmental failure of the embryonic eyeball and consequential proliferation of the embryonic neuroepithelial cells occurred at an early developmental stage causing the formation of microphthalmos with cyst.

OBJECTIVE: To analyze the clinical manifestations and the cause of misdiagnosis of congenital vallecular cyst. METHOD: Nineteen cases of congenital vallecular cysts were collected and reviewed retrospectively. Their clinical manifestations and diagnosis were analyzed. RESULT: Their clinical manifestations included inspiratory stridor, respiratory distress, inspiratory dyspnea, feeding difficulty etc. Among 19 cases, 15 cases were misdiagnosed as neonate pneumonia (9 cases), bronchial pneumonia (5 cases), and laryngitis (1 case), respectively. All cases were diagnosed as congenital vallecular cysts by fibrolaryngoscope. The diagnosis was confirmed by pathological examination. CONCLUSION Congenital vallecular cyst is fairly uncommon. To cure these patients on time, early examination of upper airway is recommended for patients with inspiratory stridor and inspiratory dyspnea. Fibrolaryngoscope would be useful for diagnosis and timely treatment.

Duplication is a rare congenital abnormality and may occur in any region of the gastrointestinal tract. A 19-year-old woman was admitted due to lower abdominal pain. Abdomino-pelvic CT scan showed a cystic mass interpreted as mesenteric cyst or duplication cyst. On the operation finding, it seemed to be arised from mesentery but attached to the ileum. Microscopically, the cystic wall was lined by non-keratinizing squamous, ciliated pseudostratified columnar epithelium, and ectopic gastric mucosa with two distinct muscular layers and a serosa. We report the first case of ileal duplication cyst lined by squamous and ciliated columnar epithelium in Korea.

Aneurysmal bone cyst (ABC) is a rare non-neoplastic bone lesion that involves mostly the long bones and vertebrae and may occur very rarely in the craniofacial bones. ABCs may occur as secondary bony pathologies in association with various benign and malignant bone tumors and with fibrous dysplasia (FD). FD is a common non-neoplastic bony pathology mostly affecting craniofacial bones. Secondary ABC occurring in craniofacial FD is extremely rare, with only approximately 20 cases reported in the literature to date. Here, we report on a case of secondary ABC in a 25-year-old woman who has had a craniofacial deformity for over 10 years and who presented to us with a rapidly growing painful pulsatile mass in the right frontal region that began over 2 months prior to admission. On thorough examination of computed tomography and magnetic resonance imaging brain scans taken at two-month interval, an aggressive, rapidly enlarging ABC, arising from the right frontal FD, was diagnosed. The patient underwent preoperative embolization followed by gross total resection of the ABC and cranioplasty. The 6-month follow up showed no recurrence of the ABC, nor was any progression of the FD noticed.

Duplication cysts are uncommon congenital malformations that may occur anywhere throughout the alimentary tract. The stomach is an extremely rare site of occurrence. Here, we report a case of gastric duplication cyst initially presenting with a gastric submucosal tumor. A 28-year-old man complained of dyspepsia lasting 1 year and upper endoscopy revealed an ellipsoid submucosal tumor at the greater curvature of the antrum. We intended to use the injection-and-cut technique: however, after saline injection, the lesion was dented and impossible to grasp with a snare. Therefore, we decided to perform endoscopic submucosal dissection and removed the tumor without complication. Histopathology revealed a 0.6x0.6 cm-sized duplication cyst, and there has been no recurrence in 2 years.

Our department treated one case of neonatal congenital cyst of tongue in March 23, 2015. The clinical manifestation of the case is mainly laryngeal stridor after birth 10d, and when infants were associated with progressive dysphagia. Electrolaryngoscope examination showed the goitre look like the cyst of tongue. Laryngeal CT scanning showed tongue lesions, consider the possibility of large cyst. Bilateral thyroid gland showed good, and no obvious abnormality was found in the cervical ultrasonography. The children was transferred to the ear-nose-throat department for excision of cyst of tongue by low-temperature plasma knife, and postoperative pathology confirmed the diagnosis of cyst of tongue.

Accessory ovary is a rare gynecologic condition, and tumors arising in accessory ovaries are extremely rare. Accessory ovary may result from separation of migrating ovaries during embryogenesis and injuries such as inflammation and operation on normal ovary. Congenital malformations, most frequently malformations of the genitourinary organ, are seen in connection with the accessory ovary. We experienced the first case of two dermoid cysts developing in an accessory ovary located in the left infundibulopelvic ligament and another in the eutopic ovary at the same side concurrently. Here, we present this extremely rare case with a review of the literature.

Primary adenocarcinoma of the seminal vesicles is a rare neoplasm. Congenital seminal vesicle cysts are commonly associated with unilateral renal agenesis or dysgenesis. To the best of our knowledge, mucinous adenocarcinoma of the seminal vesicle cyst that's associated with an ectopic ureter opening into the seminal vesicle and ipsilateral renal agenesis has not been described in the radiological literature. We report here on the radiological findings of a primary adenocarcinoma of a seminal vesicle cyst in this condition.

PURPOSE: A seminal vesicle cyst in combination with ipsilateral renal agenesis is rarely encountered. We present cases of this disease entity with symptoms, which were treated with a laparoscopic approach as a minimally invasive surgical treatment. MATERIALS AND METHODS: We experienced 4 patients with seminal vesicle cysts and ipsilateral renal agenesis. The mean age was 45.8 years. Chief complaints were perineal pain and hematospermia. Seminal vesicle cysts and remnant ureters were excised by laparoscopic surgery with transperitoneal approaches. RESULTS: The mean operative time was 133.8 minutes. The mean hospital stay was 6.8 days. There were no operative complications or transfusions. CONCLUSION: In our report, patients of congenital seminal vesicle cyst associated with renal agenesis are presented. Laparoscopy is considered a minimal invasive management of these combined anomalies, providing a good image and an easy approach.
