Neurofibromatosis type I or Von Recklinghausen's disease can occur at any site in the body. It is characterized by multiple $c\'{a}fe\;\'{a}u\;l\'{a}it$ spots on the skin-more than six spots greater than 1.5cm-, neurofibromas of the peripheral and centarl nervous system, and variety of other dysplastic abnormalities of the skin, bones, endocrine organs, nervous systems, and blood vessels. It is an autosomal dominant trait disease with a frequency of 1 of 3000. Neurofibromatosis is known to be complicated by malignancies. Neurofibromatosis is progressive disease and shows a marked variations in expression in affected individuals. In this report we describe a male patient with neurofibromatosis type I developed in the parapharyngeal space. The patient had huge mass at left parapharyngeal space and inguinal area. We successfully treated the patient with surgery without complication.

The segmental mandibulectomy should be performed, if mandiblie invasion is suspected clinically and radiologically. And if tumor is located to mandible very closely or when microinvasion to mandible is suspected, marginal mandibulectomy is recommended. But in segmental mandibulectomy, reconstruction is difficult and cosmetic problem remains. In this case, we performed modified segmental resection of mandible, preserving the inferior margin of mandible, and maintains the continuity of the bone, in mucoepidermoid carcinoma of parapharynx, invading mandible. We reviewed the diagnosis, pathology, and treatment, and report the case with reviews of literature.

An unusual case of nodal metastases from thyroid neoplasm known as parapharyngeal space mass is likely to be overlooked. And identification of the primary lesion by excisional biopsy calls for a secondary operation. Therefore, it is important to be aware of the possible lymphatic spread of the thyroid neoplasm to the parapharyngeal space. In this case, completion thyroidectomy should be considered. Here, we present a case of thyroid papillary carcinoma masquerading as a parapharyngeal space tumor. The mass was removed by transcervical approach and pathologically diagnosed as a metastatic thyroid papillary carcinoma. Successful results were obtained after additional completion thyroidectomy.

Second branchial cleft cysts are usually present as a fluctuant neck mass along the anterior border of the sternocleidomastoid muscle. When they are found in this typical location, accurate diagnosis on initial presentation is not difficult. Parapharyngeal presence of the branchial cleft cyst is very rare. We report a case of second branchial cleft cyst presenting as a parapharyngeal cystic mass in 51-year-old male. Before coming to our clinic, the patient had been diagnosed as parapharyngeal abscess, resulting in several attempts at removal. However, symptoms and parapharyngeal abscess recurred. We performed complete surgical resection of the parapharyngeal cystic mass via transoral approach only with oropharyngeal incision. The cystic mass was located in the parapharyngeal space and did not have tract-like structure. Histopathologic examination confirmed that the excised cyst was branchial cleft cyst. Patient discharged without any surgical complication and there was no evidence of recurrence for 2 years follow-up.

저자는 1988년 6월 1일부터 1993년 6월 30일까지 서울대학교병원 치과진료부에 내원하여, 병리조직학적으로 확인된 구강악안면부 악성종양환자 35명의 방사선사진 소견과 자기공명영상 소견을 비교하여 다음과 같은 결론을 얻었다. 1. 일반적인 방사선사진소견으로는 미만성의 골파괴가 15례 (42.9%), 연조직종괴의 음영이 7례 (20,0%), 부유치를 보인 경우가 3례 (8.6%), 골경화가 2례 (51.7%)로 나타났다. 2. 자기공명영상 소견은 연조직종괴가 23례 (65.7%), 골수침범이 12례(34.5%), 피질골 파괴가 14례(40.0%), 정상피질골에 골수침범이 1례 (2.9%), 지방층소실이 19례(54.3%), 림파절전이가 8례 (22.9%), 조영증강이 15례 (42.9%), 골증식이 1례 (2.9%)였다. 3. 구강악안면부의 악성종양환자에 있어서, 방사선사진에서 관찰하기 힘들었던, 종양의 구강저, 저작근, 부인두강, 사골동, 측두하와, 악하선, 비강 등 인접조직으로의 침범여부 및 골파괴 정도와 림파절전이를 평가하는 데 자기공명영상은 도움을 주었다. 4. 정진율은, 방사선사진에서 35례중 16례로 45.7%였고, 자기공명영상에서는 35례중 27례로 77.1%로 자기공명영상의 정진율이 더 높았으나, 일반적인 방사선사진이 자기공명영상보다 더 우세한 경우도 2례 있었다.
