부인두강(Parapharyngeal space)는 비인두강과 구인두강에 인접하여 위로는 두개저, 아래로는 설골사이에 위치하는 해부학적 잠재공간으로 이곳에 발생하는 종양은 매우 드무나 다양한 병리조직학적 소견을 보이며 인접한 중요장기들로 인한 수술적 어려움으로 두경부 외과의사의 관심이 되어 왔다. 최근 CT나 MRI의 도입으로 이학적 검사가 어려웠던 이부위의 진단에 많은 도움을 얻게 되었고, 발달된 수술방법의 사용으로 크기가 매우 큰 종양도 절제가 가능하게 되었다. 저자들은 1990년 9월부터 1993년 8월까지 한림대학교 이비인후과학교실에서 술전 CT나 MRI를 시행한 후 조직검사로 확진된 부인두강 종물 22례의 후향적 임상분석을 시행하여 다음의 결과를 얻었다. 1) 양성종양이 11례(30.0%), 악성종양이 11례(50.0%)로 빈도에 차이는 없었다. 2) 종양의 조직학적 기원은 타액선종양이 10례(45.5%)로 가장 많았으며 신경종양이 4례(18.2%)였고 기타 종양이 8례(36.4%)로 다양하였다. 3) 방사선학적 진단방법으로는 18례(81.8%)에서 CT를 시행하였고 필요한 경우에 MRI를 5례(22.7%), 혈관조영술을 3례(13.6%)에서 시행하였다. 4) 치료방법으로는 악성종양은 수술 및 방사선치료 또는 항암약물요법을 병리조직검사 결과에 따라 단독 또는 병합하여 시행하였고, 양성종양의 경우에는 모두 수술을 시행하였는데 수술방법은 경이하선 접근법이 가장 많이 사용되었다. 5) 추적조사는 평균 20개월로 양성종양의 경우는 모두 종양의 재발이 없이 치료되었으나 악성종양 중 전이암 1례와 악성 임파종 1례가 사망하였다.

Latissimus dorsi myocutaneous flap is useful for the breast reconstruction, chest wall coverage, free flap transfer, and head and neck area reconstruction, especially in large defect. We have had some experience of 5-pedicled and 1-free latissimus dorsi myocutaneous flap in head and neck area and found many advantages and some problems. The conclusions were as follows : 1. Potentially large flap size enabled us agressive tumor resection and reconstruction. 2. Speedy and easy flap elevation and long vascular pedicles reduced operation time and flap failure. 3. Due to fewer complication and functional loss of doner site, pedicled latissimus dorsi flap was a good choice for large head and neck reconstruction. 4. Because of flap bulkness, thin and small defect was not appropriate for reconstruction.

Purpose: Kimura's disease is an uncommon benign lymphoproliferative inflammatory disorder with an unknown etiology. The recurrence rate after surgical excision is relatively high and renal involvement is its only systemic manifestation. The condition mainly involves the head and neck, and peripheral involvement is extremely rare. Materials and Methods: We encountered the case of a 28-year-old man who had a non-tender mass with mild brownish skin color changes and pruritus around the medial side of the distal arm and elbow. Results: The peripheral blood investigation revealed peripheral eosinophilia and elevated serum IgE levels. Magnetic resonance imaging showed an isointensity signal relative to the muscle on the T1-weighted images and hyperintensity signal relative to the muscle on the T2-weighted images. Conclusion: A marginal resection of the lesion was performed and there was no recurrence at 2 years postoperatively.

Ovarian cancer is common malignant disease with high mortality in the female. However, lymph node metastasis in the head and neck of ovarian cancer is very rare than in para-aortic, pelvic lymph node. A 49-year-old female patient came to our clinic with a left neck mass. After total thyroidectomy and left selective neck dissection for the cervical neck level II, III, IV, V, VI for ovarian cancer and thyroid cancer, she had already undergone chemotherapy (Paclitaxel+Carboplatin) 18 month ago. CT scan showed only lymph node enlargement in left neck level II. Positron emission tomography-computed tomography (PET-CT) revealed a hypermetabolic lesion in same area but no other hypermetabolic lesion, especially in the pelvic and abdominal cavity. Fine needle aspiration cytology revealed metastatic carcinoma. The serum level of CA-125 was elevated to 43.8U/mL, whereas other tumor markers (CA 19-9, CEA) were in the normal range. She underwent a revision of selective neck lymph node dissection for the cervical neck levels I, II, and III, and on the review of surgical pathology, metastatic carcinoma was suspected. Thus, we performed immunohistochemical staining for the tissue; as a result, it was finally diagnosed as metastatic ovarian cancer (positive for CK7, ER and PR, and negative for CK20). Adjuvant chemotherapy (Paclitaxel+Carboplatin) was planned on the tumor board, and the patient successfully received chemotherapy.

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.

Background and Object: The role of fine needle aspiration cytology (FNAC) and frozen section (FS) in management of thyroid neoplasms continues to generate considerable controversy. We reviewed our current experience to determine the clinical utility of FNAC and FS in our surgical management and investigated reliability of FNAC and FS in planning the extent of thyroid resection. Material and Method: 212 patients who had operations for thyroid disease from May 1996 to November 2003 were included our retrospective study. FNAC was undertaken in 175 patients and FS was done in 148 patients. Result: The sensitivity and specificity of FNAC were 72.1% and 100%, respectively, and those of FS were 67.2% and 100%. The results of FNAC were benign (n=72) , malignancy (n=31), indeterminate (n=9), and nondiagnostic (n=63). The results of FS were benign (n=95), and malignancy (n=53). The 9 indeterminate cases on FNAC were benign (n=6) and malignancy (n=3) on final pathology, and benign (n=7) and malignancy (n=2) on FS. The false negative of FNAC were micro papillary carcinoma (n=6) and follicular carcinoma (n=6). The false negative of FS were micropapillary carcinoma (n=10) and follicular carcinoma (n=2). Conclusion: When results of FNAC are interpreted as indeterminate, FS is a valuable tool. FS is helpful in determining the extent of thyroidectomy when results of FNAC were follicular neoplasm. However we always concerned about micropapillary carcinoma and follicular carcinoma although FNAC and FS were benign.
