Congenital midline cervical cleft is a rare congenital disease. The disease is often misdiagnosed as a branchial cleft deformity, thyroglossal duct cyst, or other skin diseases. It has the following characteristics: skin defect at the midline of the anterior neck, a skin tag at the upper end of the lesion, and a blind sinus tract at the caudal aspect with or without mucoid discharge. Treatment is usually for aesthetic purposes; therefore, early surgical en bloc resection with Z-plasty or W-plasty is recommended to reduce recurrence and scar formation.

An oral foregut cyst is a rare congenital choristoma lined by the respiratory and/or gastrointestinal epithelium. The exact etiology has not been fully identified, but it is thought to arise from misplaced primitive foregut. This lesion develops asymptomatically but sometimes causes difficulty in swallowing and pronunciation depending on its size. Thus, the first choice of treatment is surgical excision. Surgeons associated with head and neck pathology should include the oral foregut cyst in the differential diagnosis for ranula, dermoid cyst, thyroglossal duct cyst and lymphangioma in cases of pediatric head and neck lesions.

Clincal observation was made on 76 cases of thyroglossal duct cyst and fistula with brief review of literature. All of the cases were diagnosed and treated surgically in Kyung Hee University Hospital from 1971 to 1993. The following results were obtained. 1) Most cases were under 20 years old(72.3%). and 49(64.5%) cases were male and 27(35.5%) cases were female. 2) Morphologically cystic type were found in 60(78.9%) cases and fistula type were 16(21.1%) cases. 3) Fluctuating cystic mass and pus discharge from fistula on just below the hyoid bone at midline of anterior neck were most common symptoms and signs. 4) 9(11.8%) cases were recurrent type and 4(5.3%) cases were recurred twice, at the time of first visit. 5) There were 2(2.6%) cases of having connection with the thyroid gland which were identified grossly on the operation field. 6) The entire cases were operated according to the Sistrunk procedure under the general anesthesia. 7) There was no recurrence and other complication except 4(5.3%) cases of wound infection.

Thyroglossal duct cyst (TGDC) carcinoma generally shows a favorable prognosis. If metastasis is present latently, it may not threaten the patient's life immediately. It has been shown, however, that larger than 1 cm papillary carcinoma (PC), level VI metastasis to the lymph node (LN), which is the nearest to the thyroid, independently predicts a worse prognosis. In the case presented herein, a 61-year-old female patient was diagnosed with an about 3 cm PC in the TGDC, particularly the columnar variant subtype, one of the aggressive variants. She had occult papillary thyroid microcarcinoma, but no LN metastasis. Even though she underwent the Sistrunk procedure and total thyroidectomy with central compartment neck dissection followed by high-dose radioactive iodine remnant ablation, however, the cancer cells spread to level IV neck LN, and finally to the lung. Therefore, when a patient is diagnosed with an aggressive histologic variant of PC in the TGDC, even without LN metastasis, the invasive surgical approach and close postoperative surveillance are necessary, with consideration of the risk of disease progression. Therefore, if it is possible to stratify the risk for patients, higher-risk patients can be offered a more invasive therapeutic approach.

Lingual thyroid is the term applied to a mass of ectopic thyroid tissue located on the base of the tongue in the midline. It may be found anywhere between the circumvallate papillae and the epiglottis. It is believed to be caused by developmental anomalies involving the descent of the embryologic gland anlage from its position posterior to the tuberculum impar to its normal pretracheal location between week 3 and week 7 of embryologic development. Differential diagnosis of the lingual thyroid would include lingual tonsillar hypertrophy, vallecular cyst, thyroglossal duct cyst, epidermal cyst, lymphoma. Lingual thyroid is found in approximately 1 in 100,000 people, and affected individuals have no other thyroid tissue in 70% to 100% of cases. Recently, we have experienced a case of lingual thyroid with mild dysphagia in a 48-year-old male. Now we report the case with literature review.

The plunging ranula or cervical ranula is amucous extravasation cyst of the sublingual gland. It is slightly common in females, shows no side preference, and is more prevalent in the second and third decades of life. It typically manifests as a painless, nonmobile swelling in the neck. The pathogenesis of plunging ranula is the discontinuities of the mylohyoid muscle in a position that would allow extravasation of sublingual gland mucin. The histologic appearance is characteristically of a cyst, devoid of epithelium or endothelium, with a vascular fibro-connective tissue wall containing some chronic inflammatory cells and macrophages stuffed with mucin. The correct diagnosis is essential for the most effective treatment, which is exicision of the sublingual gland. The plunging ranula must be differentiated clinically and histomorphologically from thyroglossal duct cyst, dermoid cyst, branchogenic cyst, lymphangioma, laryngocele, lipoma, hemangioma, cervial thymic cyst, cysts of the parathyroid or thyroid gland, lymphadenopathy, abscess, or tumor. We report a case and review the literatures, in our case, 23-year old man were diagnosis as plunging ranula after have been taken sialogam, MRI, etc. He underwent surgery via a cervical approach. The ranula reached the anterior neck by passing through a dehiscence in the mylohyoid muscle. A pseudocyst was extirpated. Although total sublingual gland excision was not performed, no recurrence was observed during 6 months follow-up periods.

Branchial cleft cyst is rarely encountered congenital neck disease. It is commonly believed that the branchial anomaly is persistance of remnant of the embryologic branchial apparatus. Among the patients visited Kyung Hee Medical Center with neck mass and inflammatory sign from January, 1980 to Aprial, 1994, we reviewed 26 cases of branchial cleft cysts confirmed by histopathologic findings with retrospective study on clinical aspects. The results are as follows: 1) There was no sex difference(14 male and 12 female), and most common between 2nd and 4th decade(21 cases, 80%). 2) Palpable mass was most common complaint(21 cases). In physical exam, the mass was non-tender, mobile and soft in most cases(over 80%). 3) The most common lesion site was anterior triangle in 15 cases. Along the SCM level, 21 cases were in upper 1/3, 2 cases in middle 1/3 and 3 cases in lower 1/3. 4) According to Bailey's classification, type II were 20 cases(76.9%), type I 5 cases(19.2%) and type III 1 case. 5) Among 28 cases, fistulous tract was found in 6 cases: one was complete type and 5 were incomplete type. 6) Among 26 cases before operation, 10 cases were diagnosed as branchial cleft cyst, 6 cases tuberculosis, 3 cases parotid tumor and 2 cases thyroglossal duct cyst. 7) Type of lining epithelium in histopathologic finding was stratified squamous epithelium in 22 cases(84.6%), mixed type in 4 cases(15.4%).

Background and Objectives: In most cases of benign neck cysts, surgical excision has been considered as treatment of choice. However, sometimes complete excision is very difficult, and recurrences has been occured due to insufficient surgery frequently. In this point of view, non-surgical treatment has been attempted with sclerosing agents such as picibanil(OK-432). In this study, we evaluated the efficacy of picibanil sclerotherapy for benign neck cysts. Materials and methods: We retrospectively reviewed 53 patients(27 males, 26 females) who had undergone sclerotherapy with picibanil for benign neck cysts such as ranula, lymphangioma, thyroglossal duct cyst and branchial cyst. Information was gathered with respected to age, sex, number of injections, side effect and outcome of treatment. All patients were treated with intralesional aspiration of cystic contents and injection of picibanil, and followed on neck ultrasonography or neck CT. Results: 53 patients received sonoguided sclerotherapy using picibanil(OK-432). 31 patients(41.3%) showed total shrinkage, near total shrinkage(more than 90% of volume) in 7 patients(9.3%), marked shrinkage(more than 70%) in 5 patients(6.6%) and partial shrinkage(less than 70%) in 17 patients. 15 patients(20%) reaveled no response and 8 patients showed recurrences with repeated sclerotherapy. The side effects of therapy were observed by symptoms such as fever, localized pain and odynophagia. However, these complications disappeared after several days in all cases. Conclusions: We recognized that picibanil(OK-432) sclerotherapy for benign neck cyst is a safe and effective procedures as a primary treatment before considering surgery.

Purpose: Dermoid cysts are almost always caused by congenital events. The most widely accepted pathogenesis is that the cysts are dysembryogenetic lesions that arise from ectodermic elements entrapped during the midline fusion. We report a rare case of dermoid cyst, which occurred not congenitally but newly in the subcutaneous scar tissue secondary to trauma. Methods: A 26-year-old man had a deep submental laceration caused by a car accident and got a primary wound closure 16 months ago. There were 18 cm-long submental hypertrophic scar and newly developed palpable masses inside the subcutaneous layer at the center of the scar. Initial impression was an epidermal cyst or a thyroglossal duct cyst. Ultrasonographic finding showed two cystic masses inside the scars at the submental area, but impressed dermoid cysts. The cystic masses were completely removed with W-plasty and histological examination were followed. Results: The histological diagnosis was dermoid cysts which were mainly composed of keratotic squamous epithelium in their inner surface linings and numerous skin appendages such as sebaceous glands, sweat glands, and hair follicles in their cystic lumens histopathologically. During the follow-up period of 25 months, there was no recurrence of any subcutaneous mass in the site of scar. Conclusion: We report a very unusual case of dermoid cysts developed by an acquired cause, considering that the accidental inclusion of deep skin elements caused by a trauma can be a critical origin of dermoid cysts.
