저자등은, 치온부의 종괴를 주소로 내원한 10세 남아의 하악 우측 골체부에서, 동일한 부위에 함께 발생한 골내성 거내세포 육아종과 백아질 섬유종으로 진단된 증례로, 수술시 비교적 작은 크기의 백아질 섬유종은 골내성 거대세포 육아종과 비교적 경계가 잘 지워져 있었고, 두 병소의 발생기원이 서로 다른 점으로 미루어 이들 두 병소는 서로 독립하여 동일 부위에 발생한 것으로 사료되며, 임상적인 관점에서, 거대세포 육아종은 어린나이에 비교적 병소가 크고, 제1 제2 대구치의 치근 흡수 및 피판의 천공 소견을 보여 aggressive type으로 판단되어, 소파술과 전기 소작술을 이용하여 두 병소를 만족스럽게 치험하고, 1년이 지난 현재까지 수술에 따른 후유증이나 재발의 소견을 나타내지 않기에 문헌고찰과 함께 보고하는 바이다. A giant cell granuloma and a cementifying fibroma occurring in the same lesion of right mandibular body in a 10 year old boy is presented with a 12 month follow up without recurrence or any other complications after operation. The relatively small lesion of cementifying fibroma was well delineated from the larger lesion of central giant cell granuloma, and as their origins are different each other(odontogenic or connective tissue origin), we have considered that both lesions had developed independently. Clinically, the evidencesa of aggressiveness of giant cell granuloma were also found, that is, large size, earlier age of 10, root resorption of lower right 1st annd 2nd molars and cortical perforation. With curettage and electric cauterization, we have treated both lesions satisfactorily.

This is three case-reports of pleomorphic adenomas arising from one parotid gland and two minor salivary glands treated by total parotidectomy and complete enucleation. We conclude as follows : 1. During the parotidectomy, we tried to preserve the facial nerve by retrograde approach to the trunk from the mandibular branch where it passes over the posterior facial vein. Although the paresis of the lower lip following the operation was seen, it disappeared in about 3 months. 2. Microscopically, the tumor of the first patient (case 1) contained equally myxoid and cellular components and showed well encapsulation. 3. In the second patient (case 2), the tumor revealed large areas of hemorrhage, cystic change, dystrophic calcification and stromal hyalinization, but no definite evidence of carcinoma, therefore we labeled this tumer as "atypical mixed tumor". 4. In the third patient (case 3), the tumor showed principally myxoid component and incomplete capsule, but the tumor was well demarcated. 저자등은 우측 이하선(46 세 여)과 우측 및 좌측 협점막의 소타액선(67 세 여, 28 세 여)에서 발생한 세 증례의 다형성 선종 환자에서, 우측 이하선 전적출술(증례 1) 및 종양 완전적출술 (증례 2, 3)로 치험하고 병리조직학적 검사 결과 다음과 같은 결론을 얻었다. 1. 안면신경의 보존을 위해 하악지에서 역행하여 본관에 접근하였으며, 수술 직후에 발생한 우측 하순 운동마비 증상은 3 개월 경과후 완전히 회복된 소견을 관찰하였다. 2. 현미경학적으로, 증례 1 에서는 myxoid 와 cellular 성분의 구성비율이 거의 같았으며 완전한 피낭형성을 보였다. 3. 증례 2 에서는 출혈, 낭포성 변화, 이영양성 석회화, 지질의 초자질화 소견이 관찰되었으나, 결정적인 악성 종양의 소견은 관찰되지 않아 "Atypical mixed tumor"로 분류하였다. 4. 증례 3 에서는 대부분 myxoid 한 조직으로 구성되었으며 블완전한 피막을 보였으나, 정상적인 선조직과의 경계는 명확하였다.

This is a case report of first branchial cleft cyst in 56 year old male patient, which was tentatively diagnosed as acute right submandibular abscess resulted from the periapical lesion of the lower right second molar. The results are as follows, 1. The accompanying ipsilateral inflammatory swelling resulted from the periapical lesion of lower right second molar tooth makes the diagnosis difficult 2. The onset of this case was very late in comparison to the mean discovering age of branchial cleft cysts. 3 The plain radiography using contrast media is helpful for the diagnosis of cystic lesions within soft tissues. 4 This case is a first branchial cleft cyst (Type I) which occurs less than 1% of all branchial deft anomalies.

복어의 加工貯藏을 위한 基礎資料를 얻고자 乾燥, 冷凍, 解凍過程中의 筋育組織變化를 觀察하여 다음과 같은 結果를 얻었다. 1. 복어의 筋育組織構造는 表皮, 眞皮 부분에 따라 약간의 血合肉層과 普通肉으로 構成되어 있고 皮下脂肪層이 없으며, 細胞間質, 筋隔膜등의 結締組織은 비교적 많은 편이었다. 2. 筋肉組織은 질기고 두꺼운 表皮層과 질기고 부드러운 結締組織으로 연결되어 있으며, 筋肉의 部分에 따라 전복처럼 서로 교차하는 筋纖維가 存在하였다. 3. 乾燥에 依한 組織의 變化는 乾燥初期에는 結締組織의 脫水收縮이 일어나고 相對的으로 筋束의 間隔은 벌어지며, 乾燥末期에는 筋隔膜, 筋節은 收縮하고 筋束사이는 벌어지며 筋細胞는 密集되는 現象을 나타내었다. 4. 1개월 凍結貯藏後의 氷結晶의 分布는 貯藏溫度에 따라 달랐으며 -35℃에서는 細胞內에, -10℃에서는 細胞外에 氷結晶이 생겼고 筋纖維의 凝集現象을 볼 수 있었다. 5. 1개월 凍結貯藏後 解凍한 경우 -35℃의 것에서는 거의 生鮮狀態로 復元되었으나 -10℃의 것은 脫水變形이 심하여 復元이 不充分하였고, -35℃ 凍結後 -20℃에서 3個月동안 貯藏하였던 것은 氷結晶의 흔적이 그대로 남아있고 脫水收縮이 심하며 復元狀態도 극히 不良하였다. 6. 筋肉의 均質化에서 생것은 실처럼 가늘게 으깨어지고 풀어지며, 1개월간 凍結貯藏한 것은 풀어지지 않았다. 그리고 凍結貯藏溫度의 차이에 따른 變化는 거의 볼 수 없었고, 凍結貯藏에 依해 保水性과 彈力이 低下함에 따라 收縮變形이 일어나며 단단해졌다. The observations on the histological changes of muscular tissue during the processes, such as drying, freezing and thawing were carried out to get basic data for processes and storage of puffer, Fugu χanthopterus. The results are as follows: Epidermal part is tough and thick. That is connected with muscular tissue by soft and tough connective tissue. The muscular tissue structures of puffer are epidermis, corium and partially dark muscle, without hypodermic fat. According to the respective muscular parts, there exist crossed muscle fibers like abalone. The connective tissues of intercellular materials and myocommata were found abundantly. During the courese of drying, the dehydration of muscular tissue occured on connective tissue in the early stage; thus caused widening between muscle bundles respectively. In the late stage of drying, contraction of myocommata and the widening between muscle bundles were appeared. After frozen storage for a month, distributions of ice crystal were affected deeply by freezing temperature, that is, those were observed mainly on the intracellular sites when frozen at -35℃, while on the extracellular sites when frozen at -10℃, but the ice crystals formed in both temperatures caused the condensation of muscle fibers. Thawing after frozen storage for a month, a recovery of muscle fibers and figuration were observed in muscular tissue stored at -35℃, while insufficient recovery of muscle fibers and disfiguration by dehydration at -10℃. In the observation of muscle fibers when the tissue was homogenated with 1% cold formalin, the fresh tissue was fragmented to myofibril level and intermixed like thread, while the frozen tissue for a month became rigid due to disfiguration, contraction, the loss of elasticity and water holding capacity.

A case of melanotic neuroectodermal tumor of infancy(MNTI) in 5 month old girl is presented with review of the literature. The review of literature indicated that there have been 189 reported cases of this lesion and there were 9 cases of malignant tumor for a rate of 4.8%. This rate of malignancy is very high in view of the fact that the tumor has been described as benign. And immunohistochemical study using avidin-biotin conjugate method demonstrated that this tumor had been originated from neural crest.

This is a case report of polyostotic fibrous dysplasia developed in the craniofacial region of 21 year old male patient, who had complained the buccolingual expansion of left mandibular body area, malocclusion and facial asymmetry. We could achieve statisfactory results by radical resection of the relatively well defined small lesion of mandible and by cosmetic bone shaving procedure on the widely dispersed and poorly defined lesions of cranium. But the persistent growth and recurrence of the lesions may produce loss of hearing, visual difficulties, facial paralysis and anosmia, and as it is a polyostotic type occured in the craniofacial region of male patient, the possibility of malignant degeneration should not be excluded completely and periodic recall and check up will be necessary.

This is a case report of invasive aspergillosis of the right maxillary antrum and the left lung in a 43 year-old male patient with diabetes mellitus and liver cirrhosis. The results were as follows. 1.Invasive aspergilliosis should be considered in compromised patients who have nasal symptomatology, infraorbital swelling and pain. 2.Invasive aspergillosis is a rapidly progressive mycotic infection of the sinus which may extend to the orbit, nasal cavity and cheek. 3.Surgical intervention is particularly urgent in orbital aspergillosis in patient in whom the eyesight is still preserved. 4.Diagnosis depends upon pathological demonstration of tissue invasion by organism with the typical morphology of aspergillus species. 5.Long-term antifungal drugs should be administrated postoperatively in pathint with invasive aspergillosis.
