Gastric teratoma (GT) is an exceeding rare lesion seen most often in male infants, comprising less than $1\%$ of all teratomas in children. A 2-day-old male child was preoperatively diagnosed to have gastric teratoma on ultrasonogram and abdominal computed tomography (CT). On laparotomy, Dumbbell- shape GT was located on lesser curvature of stomach and complete excision of the tumor was performed. The histological examination revealed immature teratoma of the stomach. The child is well 10 months after surgery.

Malignant melanoma of the nasal cavity occurs rarely. Malignant melanoma, originated from the upper respiratory tract including nasal cavity, has clinical feature of local recurrence and easily metastasizes to regional or distant lymph nodes, lung, and liver. Malignant melanoma originated from nasal cavity frequently shows tumor cell invasion, ulceration, or infection. Owing to these characteristics, complete surgical excision of the malignant melanoma in nasal cavity is not easy. And also the prognosis of this tumor is not so good because of a high recurrence rate. Recently the authors have recently experienced a case of malignant melanoma originated from the inferior turbinate, which was treated with lateral rhinectomy, total maxillectomy. The defect developed after surgical extirpation was reconstructed with rotational forehead flap.

An intra-articular osteoid osteoma is a very rare cause of elbow pain, and its diagnosis and treatment remain challenging. Delayed diagnosis may lead to arthritic change of the joint. In this study, the authors present the occurrence of intra-articular osteoid osteoma in the right elbow of a 15-year-old male patient who presented with prolonged pain and limited motion owing to delayed diagnosis. After confirming the nidus of osteoid osteoma from radiographic evaluation, the lesion was completely removed arthroscopically. The patient presented a complete relief of symptoms and full range of motion. This is the first domestic report of successful arthroscopic treatment of an intra-articular osteoid osteoma of the elbow.

위기형종은 모든 기형종의 1% 미만을 차지하며, 대부분 1세 미만의 남아에서 발생하고, 상복부 종괴나 복부 팽만을 주소로 내원하여 방사선학적으로 US나 CT 소견에서 위 주위에 낭성 그리고 고형성분이 섞여 있는 종괴가 지방이나 석회화를 함유한 경우 진단이 가능하며, 보고된 대부분의 경우가 양성으로 완전한 수술적 절제 후에는 추가적인 치료가 필요하지 않고 예후는 매우 양호하다. 알파 태아 단백(AFP, ${\alpha}$-fetoprotein)이 종양 표지자로 사용되며, 추적 검사에서 점차적으로 증가하거나 또는 감소하지 않는 경우 재발이나 불완전한 절제를 생각할 수 있다.

Lymphoid hamartomas are a rare benign disease which can be easily treated by complete surgical excision. They developed most often in the thorax, and can be discovered usually on routine chest X-ray.p But some of them can also be found because of pressure symptoms or the presence of a palpable mass if outside the thorax. We experienced a case of the hyaline-vascular type of lymphoid hamartoma in the left hilum of a 29 year-old Korean male in March, 1979. He was well except intermittent cough and left chest discomfort of a year duration and was treated by resection of the left upper lobe including nodular tumor masses. The histological characteristics were an aggregation of lymphoid follicles composed of concentrically arranged mature lymphocytes with centrally placed thick walled arterioles showing endothelial proliferation and some of them were hyalinized. Between the follicles, there was extensive capillary proliferation and infiltration of numerous lymphocytes, scanty plasma cells and eosinophils.

Extrapelvic endometriosis is a rare disease. The majority of extrapelvic endometriosis cases involve scar tissue following obstetric and gynecologic procedures. We have treated two cases of extrapelvic incisional endometriosis. A 39 year old female patient with cyclic vaginal spotting after laparoscopic assisted vaginal hysterectomy due to uterine myoma and a 35 year old female patient with a painful palpable abdominal mass after cesarean section. Both underwent complete excision and were proven to have endometriosis by pathology. Here we report on both cases and review the medical literatures.

Desmoplastic fibroma, which develops predominantly in long bones and the mandible, is a rare and benign but locally aggressive tumor. Desmoplastic fibroma of the cranium is extremely rare. We report a case of desmoplastic fibroma of the frontal bone in a young man. Because of its locally aggressive behavior, complete surgical excision with a safety margin is essential.

Ganglioneuroma (GN) is a rare benign tumor of neural crest origin usually found in the abdomen, but may occasionally present at uncommon sites including the cervical, lumbar, or sacral spine. However, GNs of thoracic spine are extremely rare. In this report, we describe a 12-year-old girl with giant GN in the thoracic spine, who underwent successful resection (T1-4 level) of the tumor. Histopathological examination confirmed the diagnosis. GN should be considered in the differential diagnosis of any paraspinal mass. A high index of suspicion and correlation of clinico-radiological findings is necessary in differentiating a large benign tumor from a malignant growth. Complete surgical excision is the treatment of choice; however tumor size and location need to be considered for the surgical approach (one-step or multiple surgeries). Close follow-up after surgery is mandatory.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease affecting joint synovium, tendon sheaths, bursae. The usual treatment for PVNS is a surgical excision. If destructive joint lesions have occurred, complete resections must be performed followed by arthrodesis or arthroplasty. We report a case of a pigmented villonodular synovitis involving an ankle joint which was treated by total ankle replacement for recurrence after simple synovectomy.

Chondrosarcoma is a rare entity of malignant tumor which arises from cartilaginous tissue, and the literatures on this disease are scarce. The first-line of treatment for cardiac chondrosarcoma is surgery. Due to early local recurrence and distant metastasis, the prognosis is poor even after complete surgical excision. We present a case of chondrosarcoma in the left atrium causing functional mitral stenosis which required urgent surgical intervention, and the successful treatment outcome.
