Lymphangioma is a benign, growth of lymphatic tissue that is present at birth or develops in early childhood, which may cause serious alterations in growth and developmemt. The problems with facial lymphangioma is usually releated directly to their size and to the area of the face which is involved. The lesions themselves may range from small, localized blemishes to huge facial masses involving both soft tissue and underlying bone and causing great distortion and asymmetry. The facial bones are seldom involved, but the natutal evolution of an individual lesion often cannot be accurately predicted when the child is first seen. Any changes in the underlying facial bone could be due either to a direct growth of the lesion into the bone, or secondary to pressure of the lesion growing outside the bone itself. A case of cystic lymphangioma extending from the neck to the tongue is reported. A six-year-old female was admitted because of swelling of the tongue. At that time, the tongue reportedly reached the extraoral size of 7x5x2.5cm and a soft, diffuse swelling of left anterior neck was revealed. The removal of cystic mass including left neck dissection and partial glossectomy were undertaken. The another case of lymphangioma is located on mandibular cheek. A twenty nine-year-old male was admitted because of palpable mass of the left mandibular area and fissure of palate. The radical excision of mass with mandibulectomy of body were undertuken. Thus we reported such a rare case and reviewed the lymphangioma.

Nearly 45% of all neurilemmoma occur in the head and neck area, but only 1% have an intraoral origin. The authors report two cases of uncommon neurilemmoma of the tongue. Both of them presented with a mass on the lateral border of the tongue, which was noted several days before. The lesions of tongue appeared as smooth-surfaced, well-circumscribed mass. They were excised under general anesthesia and diagnosed as neurilemmoma on histopathologic examination.

Persistance of developmental remnants during fetal life may be attributed to congenital cysts and fistulas in the neck, which are experienced rather rarely. Recently authors have experienced three cases of progressive increased tumor mass in the lateral side of the neck and four cases of tumor mass in the suprathyroid region. We have performed surgical removal under the diagnosis of branchial cysts and thyroglossal duct cysts, respectively. The biopsy specimens were confirmed by histopathological study.

Objective: To evaluate the feasibility and diagnostic performance of ultrasound (US)-guided fine-needle aspiration cytology and core-needle biopsy (US-FNAC/CNB) for the diagnosis of laryngo-hypopharyngeal masses. Materials and Methods: This was a single-center prospective case series. From January 2018 to June 2019, we initially enrolled 40 patients with highly suspicious laryngo-hypopharyngeal masses on laryngoscopic examinations. Of these, 28 patients with the mass involving or abutting the pre-epiglottic, paraglottic, pyriform sinus, and/or subglottic regions were finally included. These patients underwent US examinations with/without subsequent US-FNAC/CNB under local anesthesia for evaluation of the laryngo-hypopharyngeal mass. Results: Of the 28 patients who underwent US examinations, a laryngo-hypopharyngeal mass was identified in 26 patients (92.9%). US-FNAC/CNB was performed successfully in 25 of these patients (96.2%), while the procedure failed to target the mass in 1 patient (3.8%). The performance of US caused minor subclinical hematoma in 2 patients (7.7%), but no major complications occurred. US-FNAC/CNB yielded conclusive results in 24 (96.0%) out of the 25 patients with a successful procedure, including 23 patients with squamous cell carcinoma (SCC) and 1 patient with a benign mass. In one patient with atypical cells in US-FNAC, additional direct laryngoscopic biopsy (DLB) was required to confirm SCC. Among the 26 patients who received US-FNAC/CNB, the time from first visit to pathological diagnosis was 7.8 days. For 24 patients finally diagnosed with SCC, the time from first visit to the initiation of treatment was 25.2 days. The mean costs associated with US-FNAC/CNB was $272 under the Korean National Health Insurance Service System. Conclusion: US-FNAC/CNB for a laryngo-hypopharyngeal mass is technically feasible in selected patients, providing good diagnostic performance. This technique could be used as a first-line diagnostic modality by adopting appropriate indications to avoid general anesthesia and DLB-related complications.

Primary malignancies of hard palate are rare, espicially adenocarcinoma of minor salivary gland in hard palate. The clinical stage of the tumor and its histologic grade at the time of treatment were significant predictors of survival. A 33-year-old woman was diagnosed with stage II, polymorphous low-grade adenocarcinoma of the hard palate and treated with surgery. We thougt that she would have excellent prognosis. After that, there was no definite evidence of recurrence during 3 months. Since then, the patient herself decided to discontunue follow-up. 9 years after that she came to the hospital due to both submandibular mass without any sign of local recurrence. CT scan and biopsy of the mass revealed multiple cervical metastatic adenocarcinoma without distant metastasis and the histologic findings were similar to that of the primary hard palate adenocarcinoma. So, we present this case with the review of literature.

Pleomorphic adenoma is the most common benign tumor in the parotid gland and a parotidectomy with preservation of the facial nerve is a widely accepted treatment. We experienced a case of huge pleomorphic adenoma arising in the parotid gland with suspicious skin invasion. This present case was 67-year-old male presenting huge parotid mass $(12{\times}7cm)$ that has been present for 30 years and this tumor showed rapid-growing nature recently. The overlying skin surface was ulcerated with serous discharge and tightly adherent to the mass. The risk of malignant transformation of a pleomorphic adenoma increases with the duration of disease. The preoperative tentative diagnosis was carcinoma ex pleomorphic adenoma in the parotid gland. The initial pathologic diagnosis of fine needle aspiration biopsy was unsatisfactory smear. After parotidectomy, the histologic examination revealed that the parotid tumor was benign pleomorphic adenoma. We present a case of huge pleomorphic adenoma with skin invasion in the parotid gland with review of literatures.

Out of entire salivary tumor, 1.7% are malignant lymphoma developed in salivary gland and it is usually mucosa associated lymphoid tissue (MALT) lymphoma developed in salivary gland. In the case of Non-Hodgkin lymphoma, the most frequently involved extanodal sites of diffuse large B cell lymphoma are bone, skin, thyroid, gastrointestinal tract, and lung. Development in salivary gland is very rare. A 69 years old male patient who have found Lt. submandibular gland (SMG) mass a month ago is suspected of malignancy from his FNA result, so histologic exam by SMG resection was operated. According to histopathologic exam, large B cell lymphocyte infiltratration were generally shown as diffuse and lymphoepitheliallesion were not found. In immunostaining, CD79a showed positive and CD3, CAM5.2 showed negative which diagnosed as diffuse large B cell lymphoma. As Ann Arbor stage I, CEOP-B chemotherapy was used 3 times as treatment without any recurrence. In the case of malignant lymphoma in salivary gland, it develops as painless mass in ipsilateral side. If found in parotid gland, it is rare to have facial nerve falsy and pathologically diagnosed as lymphocytes of abnormal type of monoclonal immunostaining must be provided as evidence. Combined therapy is known as most effective treatment for intermediate grade.

Objectives: This study aimed to assess hand grip strength and femoral neck bone mineral density levels among Korean fishery workers and investigate their association. Methods: Hand grip strength and femoral neck bone mineral density were measured in a survey and health examination conducted in 2021 among fishery workers in a southern region of South Korea. Covariates including gender, age, education level, income level, smoking behavior, drinking behavior, family history of hip fractures, use of calcium and vitamin D supplements, hypertension, diabetes, regular exercise, and body mass index were investigated. Multiple regression analysis was employed to assess the association between hand grip strength and femoral neck bone mineral density. Results: Among 147 fishery workers, 8.16% exhibited low hand grip strength levels indicative of possible sarcopenia, and a significant association was found between low hand grip strength and decreased femoral neck bone mineral density (β = -89.14, 95% CI = -160.50, -17.78). Additionally, factors such as women gender, advanced age, family history of hip fractures, and a body mass index below 25 kg/m² were associated with decreased femoral neck bone mineral density. In the subgroup analysis by gender, a correlation between low hand grip strength and decreased femoral neck bone mineral density was observed only in men. Conclusions: Further research is needed to explore various determinants and intervention strategies to prevent musculoskeletal disorders among fishery workers, ultimately enhancing their quality of life and well-being.

Pilomatricoma is a benign neoplasm of the hair follicle origin which most common occur in the head and neck, particularly in the cheek and preauricular region. This neoplasm is superficially located and stony, hard consistency on palpation and sometimes shows reddish or bluish discoloration on the overlying skin. The diagnosis is confirmed by histopathologic examination. Radiologic evaluation is little diagnostic and fine needle aspiration biopsy often misdiagnose because both tissues from basaloid cell component and shadow cell component should be obtained for correct diagnosis. And Otolaryngologist should consider the possibility of philomatricoma when childhood or early adulthood persion visits with hard, supferficial mass on the parotid or cheek area. The treatment of choice is surgical excision with clear resection margin. In many instances, overlying skin excision is needed. We report 4 cases of philomatricoma arising from preauricular, cheek and posterior neck.

Oncocytic neoplasm of the head and neck region accounts for approximately 1% of all salivary gland tumors, but only 5% of oncocytic neoplasm is malignant. Oncocytic carcinoma arising in the submandibular gland is exceedingly rare. We encountered a sixty seven-year-old male patient who presented with multiple mass in the right neck. Fine needle aspiration biopsy revealed a salivary gland tumor of predominantly oncocytic form, and a differential diagnosis included oncocytic adenoma or mucoepidermoid carcinoma. A right submandibular gland resection and modified radical neck dissection were performed. Histologically, the tumor cells showed nuclear pleomorphism, and stromal invasion, which were compatible with oncocytic carcinoma. After surgery, the entire neck region was irradiated. Seventeen months after the initial surgery, multiple metastases to the bone and lung were detected from the incidental pathologic bone fracture of the right humerus; palliative chemotherapy was performed to resolve this. We report a case of oncocytic carcinoma in the submandibular gland with a review of literature.
