종격동 지방모세포종은 미성숙 지방세포에서 발생하는 드문 양성 종양으로 주로 영아기에서 나타난다. 예후는 좋으나 종종 급격히 성장하거나 국소적으로 침범하기도 한다. 본 증례는 전 종격동에 발생한 지방모세포종으로 인해 빈번하게 폐렴이 발생한 3세 여아에 대한 보고로서, 흉부 컴퓨터 단층 촬영에서 심낭과 우측 폐 종격동 흉막 사이에 위치하여 주변장기를 압박하는 지방함유 종괴로 내부에 석회화나 낭성 조직을 함유하지 않았으며 완전 절제 후 병리 조직 검사에서 지방모세포종으로 진단되었다. 현재까지 합병증이나 재발의 증거 없이 외래 추적 관찰 중이다.

Benign triton tumor (BTT) or neuromuscular hamartoma is an uncommon tumor composed of mature neural and well-differentiated striated muscular elements. Its development is exceptionally rare in the adult and head region. This report describes a case of adulthood BTT that occurred in the orbit. The patient was a 53-year-old woman who presented with right periorbital swelling and pain in eyeball over 2 months. Magnetic resonance imaging revealed a well-enhancing mass surrounding optic nerve and ocular muscles in the right retrobulbar area. The tumor was subtotally removed via transcranial approach. Its pathological diagnosis was confirmed to be a neuromuscular hamartoma. She developed diplopia postoperatively. Adulthood BTT should be considered in the differential diagnosis of head and neck tumors. It is also important to make adequate therapeutic strategy to avoid postoperative neural dysfunction.

Benign hyperplasia of hilar lymph glands is rare. Most of the lesions were intrathoracic cavity. The lesions were discovered most often on routine roentgenograms of the chest or because. of pressure symptoms or the presence of a palpable mass if outside the thorax. Diagnosis is. made after removal of gland, a procedure which may also have therapeutic value. They have been divided into 2 histol0gic types: the hyaline-vascular lesions, which were, most numerous, were characterized by small hyaline-vascular follicles and interfollicular capillary proliferation ;the plasma cell lesions were characterized by large follicles with! intervening sheets of plasma cells. We experienced one case of benign hyperplasia of lymph gland in left hilum, which were. most numerous, characterized by small hyaline-vascular follicles and interfollicular capillary proliferation-hyaline-vascular type. This 29 years old male patient was treated by right upper lobectomy with excision of lesion. The postoperative courses was uneventful.

Fibrous histiocytomas are commonly occurred in the skin of the extremeties and rare in the head and neck region. Fibrous histiocytomas in general are considered benign tumors. But deep fibrous histiocytomas have more poor prognosis than cutaneous counterparts and tendency of local invasion and recurrence. Wide surgical excision is the treatment of choice due to high recurrence rate and potential malignancy. We presented a rare case of benign fibrous histiocytoma occurred in the superficial lobe of the right parotid gland, showing palpable mass with pain.

Primary neoplasms of the pericardium are rarer than those originating within the myocardium or endocardium and, moreover, primary benign tumors of the pericardium are of much rare occurence. Mahaim[1945] was able to collect 84 cases of pericardial tumors, the majority of which were malignant. A case of primary benign fibromyxoma of the pericardium is presented. This tumor arouse in the right anterior aspect of the pericardium, through which the phrenic nerve was penetrated. The tumor was measured 10X6X6 cm in size and 120 gm in weight. Total excision of the mass was accomplished by antero-lateral thotacotomy incision, resulting complete cure. This is the first case of primary benign fibromyxoma of the pericardium on literatures in our knowledge.

Foregut cystic developmental malformations are rare developmental anomalies. It is important to diagnose the diseases and manage them properly because these cysts may generate feeding or respiratory difficulties depending on the size and location of the lesions. A newborn was referred for a congenital cervical swelling to our clinic on the second day of his life. Neck SONO and MRI showed an about 6cm sized cystic mass at left submandibular area. Aspirations and sclerotherapies were done repeatedly due to recurred cystic mass. Under the suspicious of cystic hygroma, the mass and submandibular gland were excised. Histologically, it was a benign cyst including gastrointestinal and bronchogenic mucosa and pancreatic tissue. Foregut cyst was suggested for the final diagnosis and the patient was discharged at 9 days after the operation without a complication. He has visited our out-patient department. Although several image studies have been introduced to find out foregut cyst, it is difficult to go through differential diagnosis because of similarity of other benign tumor. Further studies for early diagnosis of cervical foregut cyst are needed for preventing possible related problems.

The incidence of chest wall tumor is rare than those of other portions of the body. The chest wall tumors need special attention about their diagnosis and management than other tumors. From March, 1985 to September, 1994, 33 patients with chest wall tumor underwent surgical treatment, and those were consisted of 28 benign tumors and 5 malignant tumors arising from soft tissue, rib and sternum.Benign tumors were included 11 lipoma, 4 cysticercosis, 2 chondroma and 1 each of fibroma, dermatofibroma, osteochondroma, fibrous dysplasia and hemangioma,and 6 other cases. Malignant chest wall tumors were included 2 metastatic carcinoma,1 each of giant cell tumor, chondrosarcoma and epithelioid sarcoma.Sex ratio of male to female was 1.5:1, and the range of age was 16 to 72 years,and the mean age was about 40 years. Clinical manifestations of chest wall tumor were palpable mass[55% , pain[21% ,tender mass[9% , growing mass[9% and asymptomatic[9% .The all cases were treated surgically, the results were as follows:Local excision 16 cases, wide resection 12 cases, wide resection with chemotherapy 3 cases, each one case of wide resection with radiotherapy and wide resection with chest wall reconstruction.

초음파 검사는 연부조직 종물 평가를 위해서 일차적으로 시행할 수 있는 효과적인 검사로 알려져 있다. 저자들은 좌측원위 대퇴부에 통증을 동반한 표재성 연부조직 종물로 내원한 환자의 초음파 검사에서 양성 종양으로 판단되었으나 수술 후 조직검사에서 활막육종으로 진단된 증례를 경험하여 문헌고찰과 함께 이를 보고하고자 한다.

Here we report a case of a focal atypical proliferative nodule (PN) arising from a congenital melanocytic nevus (CMN). Diagnosis was challenging because it had both benign and malignant clinical features. Unusual histopathology, immunohistochemistry, and intraoperative findings of this atypical PN are discussed. A 5-year-old girl was admitted for a congenital $5{\times}5cm$ sized scalp mass. This hemangioma-like soft mass showed biphasic characteristics such as a slow, gradual, and benign increase in size but worrisome dural invasion with cranial bone defect. We removed the scalp mass with clear resection margins. Interoperatively, we found that the cranial bone defect had already filled. Histopathologic examination showed CMN with focal atypical PN. The nodule showed sharp demarcation and cellular pleomorphism. However, in immunohistochemical study, Ki-67 proliferation index and expression levels of protein S-100 and Melan-A were very low. These were unusual findings of atypical PNs. Despite her worrisome preoperative radiologic features, she showed an indolent clinical course compatible with previously reported biologic behavior. The patient underwent follow-up inspection with magnetic resonance imaging every 6 months for up to 3 years. The nodule appeared to be stationary at the last visit.

A 13-yr-old Shih tzu was referred for surgical management of right-sided cranial abdominal mass, which corresponded to large, cavitated renal mass on ultrasonography, and was suspected to represent neoplasia. Intraoperative impression smear cytology (ISC) of the renal mass wall was consistent with benign renal cyst (RC), without evidence of neoplasia or infection. Deroofing and omentalisation were performed and histopathology was consistent with benign RC. Chronic kidney disease was diagnosed 4 mon postoperatively, however, the dog was asymptomatic, without cyst reoccurrence. Intraoperative ISC is an expedient and inexpensive diagnostic technique that can guide most appropriate treatment in dogs with large RCs.
