Mastoid lymph node inflammation is a rare entity. Pathological conditions in the vicinity of the mastoid processes can be challenging for maxillofacial head-neck surgeons to address. We report a case of suppurative mastoid lymphadenitis in an 18-year-old Caucasian male. To our knowledge, there are no publications that highlight the clinical, ultrasonographic, intra-, and postoperative data for any pathologic process that presented as mastoiditis.

A pathologic review was made of 1547 cases of thyroid nodule during the 20 years from 1970 to 1989 at the department of Head and Neck surgery of Presbyterian Medical Center in Chonju. 1547 cases were analysed in regard to cancer incidence of thyroid nodule, correlation of preoperative diagnosis with pathology and of frozen section diagnosis with final pathology, surgical procedures employed in managing thyroid itself, location of metastatic nodes, further definite procedure in cnacer cases, effectiveness of prophylactic neck dissection with lymph node pathology. The results are summarized as follows: 1) The cancer incidence of thyroid nodule was 21.7%. 2) The incidence of thyroid cnacer in total neoplasms increased from 1.6% to 2.9%. 3) The thyroid cancer was prevalent in female(5.9:1) and in fifth, fourth and sixth decade of life. 4) The incidence of solitary cold nodule in thyroid cancer was 72.7% (210/289). S) The incidence of thyroid cancer in solitary cold nodule was 28.7% (210/782). 6) The false negative of frozen section (1240 cases) was 19.8%. 7) Histologically, well differentiated carcinoma comprises about 94% of all cases and papillary carcinoma was 78.5% of all cases 8) The most frequent lymphatic metastasis was pre- & paratrachel nodes(63.3%), followed by Level III(50%) and Level II(47.7%). 9) 47.7% among 130 cases of papillary adenocarcinoma and 12.5% among 16 cases of follicular adenocarcinoma, each group treated with prophylactic neck dissection, were confirmed to be occult cervical node metastasis.

The authors reviewed 114 cases of malignant major and minor salivary gland tumors at Presbyterian Medical Center seen from February, 1963 to December, 1983. The results were obtained as follows; 1) Overall male and female sex ratio was 2:1. The peak age of patients with major and minor salivary gland tumor were both 5 th decade. 2) The ratio of benign and malignant tumor was 83:114. The incidence of malignancy in each group was 52% in parotid (50 patients), 75% in minor salivary gland (45 patients), 49% in submaxillary gland(18 patients) and 25% in sublingual gland (1 patient). 3) The incidence according to the anatomic primary site for minor salivary cancers was 10 cases in the nasal cavity, each 8 in the palate and the maxillary antrum, 7 in the tongue, 5 in the gum, 3 in the larynx and 2 in the buccal mucosa. 4) Adenoid cystic carcinoma was the most common cancer of minor salivary gland and malignant mixed tumor was the most common in major salivary glands, each comprising 34 cases (76%) of minor and 19 cases (28%) of major salivary gland tumors. 5) The incidence of cervical lymph node metastasis was 50% in the submaxillary gland cancers, 44% in the parotid gland cancers and 21% in malignant tumors of minor salivary glands. The highest incidence of lymph node metastasis according to histopathological classification was formed in high grade of mucoepidermoid (67%). 6) Nerve invasion was common in mucoepidermoid carcinoma. According to anatomic site, nerve invasion occurred most often in adenoid cystic carcinoma of the submaxillary gland (44%). 7) The lung was the commonest site for distant metastasis comprising 12 cases among 26 cases in which distant spread occurred. 8) The recurrence rate was 50% for major salivary gland cancer and 52% in cancer of the minor salivary gland. In accordance with pathological classification, adenocarcinoma most frequently recurred after excision. This being seen in 88% of patients undergoing definitive therapy. 9) The determinate 5 year survival rate was 78% in major salivary gland tumors, but 69% in minor salivary gland tumors.

Salivary duct carcinoma is a high-grade adenocarcinoma arising from the ductal epithelium and has very low prevalence. We report a case of salivary duct carcinoma in high risk group with satisfactory result. A 65-year-old male was referred to our clinic complaining of mass on Rt. cheek. Preoperative CT and MRI shows $2.0{\times}1.9cm$ sized multilobulated, cystic mass on the superficial lobe of Rt. parotid gland and multiple lymph node enlargement thorough the Rt. internal jugular chain. Total parotidectomy and modified radical neck dissection with adjuvant radiation therapy was performed. Pathologic result was salivary duct carcinoma and resection margin was free. Postoperative radiation therapy with 6400 cGy($200cGy{\times}12fx$) was performed. During the 24-months of follow up periods, recurrence or complications associated with operation and radiation therapy was not observed. Salivary duct carcinoma is rare disease with very poor prognosis. Lymph node metastasis is commonly accompanied at the time of diagnosis. Distant metastasis is the most common cause of death. Total parotidectomy, radical neck disssection and adjuvant radiation therapy can be the appropriate modality for the control of the salivary duct carcinoma especially in high risk group.

Background and Objectives: Recently the tenn 'papillary microcarcinoma' has been proposed to designate carcinoma of 10 mm or less in diameter. In some cases, cervical lymph node metastasis preceding the occurrence of the primary tumor may be the first and sole manifestation of the disease. The objective of this study is to assess the clinical features of cervical metastasis in papillary microcarcinoma of thyroid glands. Materials and Methods: 9 cases with papillary microcarcinoma with neck metastasis were analyzed retrospectively. 5 cases are men and 4 are women. All patients complained of painless, movable neck mass. The symptom had been present from 1 month to 36 months. We reviewed clinical history, imaging studies, the results of fine needle aspiration, the surgical method, the pathologic results. Results: In 9 cases, no abnormalities of the thyroid gland were shown by imaging studies and thyroid scan. 3 cases were diagnosed by fine needle aspiration cytology. the others were not. Total thyroidectomy and neck dissection were performed in 9 cases and then pathology reports showed 2 case of multiple, 2 case of contralateral single and 5 cases of unilateral single thyroid microcarcinoma. They have no recurrence during follow-up period. Conclusions: Cervical metastasis from papillary microcarcinoma is variable clinical manifestation. The diagnosis of cervical metastasis from papillary microcarcinoma should be considered in patient with neck mass. We recommend total thyroidectomy with neck dissection and postoperative radioactive iodine ablation therapy in neck metastasis from papillary thyroid microcarcinoma.

목적: 두경부 편평상피암 환자에서 경부림프절전이에 대한 F-18 FDG PET/CT의 진단성적을 평가하고 CT/MRI와 비교하였다. 대상 및 방법: 수술전 조직검사로 편평상피암으로 진단받은 17명(남: 15명, 여: 2명, 평균나이: $59{\pm}11$세)의 환자를 대상으로 F-18 FDG PET/CT를 시행하였다. 경부림프절의 F-18 FDG섭취 정도는 세 등급(1=배후방사능, 2=간방사능보다 낮거나 같은 경우, 3=간방사능보다 높은 경우)으로 나누었고, 3등급일 때 전이로 진단하였다. 경부림프절전이에 대한 F-18 FDG PET/CT의 예민도와 특이도를 CT/MRI와 비교하였다. 결과: 17명의 환자에서 123개의 경부림프절이 절제되었고 이 중 29개가 전이로 확진되었다. F-18 FDG PET/CT의 예민도는 69%(20/29), 특이도는 99%(93/94), CT/MRI의 예민도는 62%(18/29), 특이도는 96%(90/94)로 경부림프절전이에 대한 두 검사의 진단성적은 유의한 차이가 없었다. 그러나 F-18 FDG PET/CT는 각각의 환자에서 간에 생긴 이차성 원발암과 늑골전이를 발견할 수 있었다. 결론: 두경부 편평상피암에서 경부림프절 전이에 대한 F-18 FDG PET/CT의 특이도는 매우 높았지만 예민도는 비교적 낮았고 CT/MRI와 유의하게 다르지 않았다. F-18 FDG PET/CT의 비교적 낮은 예민도의 원인은 최근 많이 절제되고 있는 잠재 전이의 가능성이 있는 작은 경부림프절을 발견하지 못하는 F-18 FDG PET/CT 의 한계 때문이었다. 그러나 F-18 FDG PET/CT는 이차성 원발암과 원격전이를 부가적으로 평가할 수 있어 환자의 치료 방침 결정에 유용하였다.

Background: Skin cancer is the most common type of cancer. Of the 4 million skin lesions excised annually worldwide, approximately 2 million are considered cancerous. In this study, we aimed to describe a regional experience with skin cancers treated by a single senior surgeon and to provide a treatment algorithm. Methods: The medical records of 176 patients with head and neck non-melanocytic skin cancer (NMSC) who were treated by a single surgeon at our institution between January 2010 and May 2016 were retrospectively reviewed, and their data (age, sex, pathological type, tumor location/size, treatment modality) were analyzed. Patients with cutaneous squamous cell carcinoma (cSCC) who were classified as a high-risk group for nodal metastasis underwent sentinel node mapping according to the National Comprehensive Cancer Network guidelines. Results: Among the patients with NMSC who were treated during this period, basal cell carcinoma (BCC; n=102, 57.9%) was the most common pathological type, followed by cSCC (n=66, 37.5%). Most lesions were treated by complete excision, with tumor-free surgical margins determined via frozen section pathology. Thirty-one patients with high-metastasis-risk cSCC underwent sentinel node mapping, and 17 (54.8%) exhibited radiologically positive sentinel nodes. Although these nodes were pathologically negative for metastasis, 2 patients (6.5%) later developed lymph node metastases. Conclusion: In our experience, BCC treatment should comprise wide excision with tumor-free surgical margins and proper reconstruction. In contrast, patients with cSCC should undergo lymphoscintigraphy, as nodal metastases are a possibility. Proper diagnosis and treatment could reduce the undesirably high morbidity and mortality rates.

Non-Hodgkin's Lymphoma(NHL) is a malignant tumor that is derived from the lymphatic system. The most common symptoms of NHL are painless lymph node enlargement. However, we should not diagnose NHL by only fragmentary clinical symptom and radiologic finding because of the various lymphoma characters. We have treated a patient with such preoperative findings of Branchial cleft cyst. However, the pathologic diagnosis of the surgical specimen was diffuse large b-cell lymphoma.

Spindle cell lipoma, a rare variant of lipoma, is a benign tumor found in the posterior neck and shoulder. A 24-year-old man with a close family history of malignant lymphoma had presented with a large, firm, nodular mass found in the right supraclavicular area. Excision of the deeply located mass revealed a pale yellow, rubbery nodule which grossly resembled an enlarged lymph node, with a variant of lymphoma as a primary suspect. However, pathological studies revealed the lesion to be a spindle cell lipoma. Although atypical in location, spindle cell lipoma should always be kept in differential diagnosis of a newly-noted soft tissue mass, as this entity may be easily cured by simple excision.

Multiple primary cancer is defined as the discrete primary cancers in an individual originating in different sites or tissues. Billroth, in 1869, first reported the occurrence of different primary malignant cancers in the same patient. Because early diagnosis and treatment are key to good survival and cure rates, clinicians should be more aware of the possibility of multiple primary cancers in an individual patient with malignant tumor. The authors recently experienced a case of fifth primary cancer, their sites of origin were lung, glottis, lymph node, supraglottis, common bile duct. We report this case with a brief review of literatures.
