About 20% of non-Hodgkin' lymphoma occur in the extra-nodal region in the head and neck area and more than half of extra-nodal lymphoma in the head and neck area involves the Waldeyer' ring. Malignant lymphoma arising in the parotid glands are relatively rare, although 90% of all salivary gland lymphomas, appear in parotid gland and are classified as extranodal non Hodgkin' lymphoma. We experienced one rare case of non-Hodgkin' lymphoma in the right parotid gland, with a painless swelling of the cheek region as the chief complaint. We treated with CHOP(cyclophosphamide, $750mg/m^2$ i.v. day1 ; doxorubicin, $50mg/m^2$ i.v. day 1 ; vincristine, $1.4mg/m^2$ i.v. day 1;prednisone, $50mg/m^2$ orally days 1 to 5. repeat every 21 days) and Rituximab combination therapy. We aimed to report here one case of non-Hodgkin' lymphoma in the right parotid gland with review of literature.

Hamartomas are non-neoplastic malformations or congenital errors of tissue development. Hamartoma is composed by an excessive growth of mature tissue present in wrong proportions and abnormal arrangements. The lesion usually presents as a submucosal mass with ill-defined margins. Hamartoma occurs in all areas of the body, especially in the liver, spleen, kidney and lung. However, hamartoma is very rare in the head and neck. Presenting symptoms of hamartoma are typically vague and nonspecific. Treatment of hamartomas consists of adequate surgical excision. We present a 59 year-old male patient who presented with submental swelling. Malignancy could not be ruled out with preoperative radiologic examination, so surgical excision was planned. The mass was excised with transcervical approach. Histopathologic examination has confirmed the mass as a mucinous gland adenomatoid hamartoma.

Parathyroid carcinoma is very rare malignant neoplasm, accounting for less than 0.005% of all cancers. Most parathyroid carcinoma is a functioning tumor that causes hyperparathyroidism, leading to hypercalcemia. We report a parathyroid carcinoma case that was suspicious for spontaneous infarction of cancer, leading to resolution of hypercalcemia. A 29-year-old male visited our hospital presenting with right neck swelling and pain. He has been experiencing frequent urolithiasis for four years but laboratory tests showed normal serum calcium level. Right vocal cord paresis was identified with laryngoscopy. Ultrasonography revealed a 3.7 × 3.5 cm mass in the right thyroid containing a focal cystic portion. Computed tomography confirmed the presence of a low-density right thyroid mass. Right thyroid lobectomy was performed and pathological evaluation revealed parathyroid carcinoma with central necrosis. We report this very rare case with a literature review.

Actinomycosis is an unusual granulomatous infection caused by gram-positive anaerobic bacteria called Actinomyces species(predominantly Actinomyces israelii), which is a common and normally nonpathogenic organism found in the nose and throat. The three major clinical presentations of actinomycosis include the cervico-facial(the most common, 55%), thoracic, and abdominopelvic region. Actinomycosis typically has a chronic, indolent course characterized by swelling and induration of the soft tissues and eventual spontaneous drainage through multiple sinus tracts. Actinomycosis is difficult to diagnose because of variable presentation mimicking neoplasm and fastidious nature of the organism in culture. We present a case of actinomycosis in the parotid tip area which was mistaken for a salivary tumor.

Warthin's tumor is the second most common tumor of the parotid gland after pleomorphic adenoma. It is well known to occur as bilateral and multiple patterns. The incidence of extraparotid Warthin's tumor (EPWT) is about 2.7% to 12%, peri-parotid and upper cervical area are the most common sites. Warthin's tumor with synchronous intraparotid and extraparotid area is extremely rare, only a few cases have been reported. We report a-71-year old man with unilateral swelling of the parotid area and upper neck, pathologically confirmed Warthin's tumor with literature review.

Background: Pediatric deep neck infection can cause critical complications in that they are seldom able to verbalize symptoms or cooperate with physical examination. The objective of this study is to identify the clinical characteristics according to age. Material and Method: A retrospective study was performed on 26 cases with pediatric deep neck infection during 12 years. Patients were classified infancy group (1-7 yr, 19.2%), preschool age group (7-15 yr, 30.8%) and school age group (15 yr-, 50%). We analyzed the age, sex, sites of abscess, predisposing factors, symptoms and compared onset, hospital date, laboratory and outcomes at each group. Results: In pediatric patients with deep neck infection, the age distribution was 18 males (69.2%) and 8 females (30.8%), the mean age was 7.4 years. The most common infection site was the anterior cervical triangle and submandibular space (19.2%). The most commonly known associated preceding disease was upper viral infection (34.6%), but we could not find the preceding diseases in most of cases (50%). Neck swelling (69.2%) was the most frequent symptom. The mean age of patients who performed neck CT was 8.23 years and neck US was 2.75 years. The younger patients were preferred to perform the neck US than the neck CT (p=0.022). The mean time from disease onset to admission was 9 days in the infancy, 5.5 days in the preschool aged and 5 days in the school aged group. The surgical treatment was performed in 30.8% of school aged, 62.5% of preschool aged and 100% of infancy group. Surgical treatment was preferred to younger patients (p=0.026). Conclusion: Abscess sites, size, and antibiotics susceptibility and especially patient age should be carefully considered in treating pediatric deep neck infection.

Objectives: Kinesiology tape (KT) creates a pulling force on the skin, thus improving blood and lymph flow by alleviating hemorrhage and congestion of lymphatic fluid. The authors hypothesized that the use of KT could be beneficial for the management of complications after head and neck surgery and designed this study to evaluate the effects of KT on swelling, pain, and trismus after enucleation of mandibular dentigerous cysts with third molar extraction. Materials and Methods: Forty patients who underwent enucleation of a dentigerous cyst with extraction of the mandibular third molar were selected. The patients were randomized into two groups (n=20 each): a KT group, where KT was applied after surgery in addition to basic postoperative care, and a control group, where patients received basic postoperative care without KT application. Swelling, pain, and trismus were evaluated before surgery (T0) and on postoperative days 1 (T1), 2 (T2), and 3 (T3). Cyst volume, gauze weight for assessing bleeding, and operation time were recorded. Results: There was a significant difference between the two groups in the change in swelling up to T1 and the change in swelling between T1 and T2. The maximum swelling in the KT group was significantly less than that in the No-KT group and maximum swelling appeared faster in the KT group than in the No-KT group. Both groups showed a mild pain response but there was no significant difference between the two groups. There was no significant difference on interincisal distance change between the two groups. There were no correlations between cyst volume, bleeding, operation time, and maximum swelling. Conclusion: KT can effectively manage facial swelling after oral and maxillofacial surgeries such as cyst enucleation and third molar extraction, thus improving postoperative patient satisfaction levels and quality of life.

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.

Plunging ranula is occured in about 10% of all ranula cases although surgery is the first choice therapy. However, frequent recurrences of the disease due to insufficient surgery have been reported, and various therapies have been designed in addition to surgery. We here report a case on whom we conducted intralesional injection of OK-432 for recurrent plunging ranula. A 36-year-old man was admitted who had a 2-months history of swelling of right submandibular area. He had been operated for right plunging ranula twice, 7 years ago. Under fluoroscopic guidance, contents of the ranula were aspirated and OK-432 solution was injected twice with 3-week interval. Examination after 6 weeks showed that the cystic ranula seen before therapy had disappeared completely and no recurrence was encountered after 18months. Therefore the intralesional injection of OK-432 is effective method for treatment of the plunging ranula.

Nasopalatine duct cysts are the most common non-odontogenic developmental cyst originating in the incisive canal of maxilla and occuring in approximately 1% of the population. Clinical presentation is mostly asymptomatic in small cysts, but sometimes shows swelling, pain and drainage when it is infected. The definite diagnosis should be based on clinical, radiological and histopathologic findings. Marsupialization of the cystic tissue can be performed, however, complete surgical excision is the the choice of treatment of nasopalatine duct cysts. We report a case of nasopalatine duct cyst occurred in the midline of hard palate treated by complete excision via transoral approach.
