Background Glomus tumors were first described by Wood in 1812 as painful subcutaneous tubercles. It is an uncommon benign neoplasm involving the glomus body, an apparatus that involves in thermoregulation of cutaneous microvasculature. Glomus tumor constitutes 1%-5% of all hand tumors. It usually occurs at the subungual region and more commonly in aged women. Its classical clinical triad consists of pain, tenderness and temperature intolerance, especially cold sensitivity. This study reviews 15 cases of glomus tumor which were analyzed according to its anatomic location, surgical approach and histologic findings. Methods Fifteen patients with subungual glomus tumors of the hand operated on between January 2006 and March 2013, were retrospectively reviewed. Patients were evaluated preoperatively with standard physical examination including ice cube test and Love's test. Diagnostic imaging consisted of ultrasonography, computed tomography, and magnetic resonance imaging. All procedures were performed with tourniquet control under local anesthesia. Eleven patients underwent excision using the transungual approach, 3 patients using the volar approach and 1 patient using the lateral subperiosteal approach. Results Total of 15 cases were reviewed. 11 tumors were located in the nail bed, 3 in the volar pulp and 1 in the radial aspect of the finger tip. After complete excision, patients remained asymptomatic in the immediate postoperative period. In the long term follow up, patients exhibited excellent cosmetic results with no recurrence. Conclusions Accurate diagnosis should be made by physical, radiologic and pathologic examinations. Preoperative localization and complete extirpation is essential in preventing recurrence and subsequent nail deformity.

Localized forms of giant cell tumor are known to arise commonly in the synovial membrane of the finger joints. Multinucleated giant cells are its characteristic pathology finding, giant cell tumor shows a low rate of recurrence after complete excision. When occurring at the knee joints, giant cell tumor manifests a wide form of symptoms, from no symptom at all, to intermittent locking. Complete excision is possible by arthroscopy, but if done incompletely, it is reported to recur in 45% of cases. We present here a case of giant cell tumor that has arisen from the anterior portion of the posterior cruciate ligament, excised by arthroscopy and followed by pathologic confirmation.

Teratomas arising from totipotential primitive germ cell are composed of 2 or 3 germ cell layers. We reviewed the records of 166 children who underwent the operation for teratoma from Jan, 1990 through April, 2007. There were 40 boys and 126 girls (average age $6.93{\pm}5.83$ years). Primary sites were ovary (n = 88), sacrococcygeum (n = 24), testis (n = 16), retroperitoneum (n = 16), mediastinum (n = 8), brain (n = 4), thymus (n = 3) and a single tumor involved the adrenal gland, neck, middle ear, oropharynx, stomach, pelvis, omentum, chest wall and scalp. Teratomas were mature in 141 patients, and immature in 25. Six patients who had ovarian immature teratomas grade 2 or 3 with peritoneal gliomatosis underwent adjuvant chemotherapy. During follow up period, 6 mature teratomas recurred at sacrococcygeal area (n = 1) and contralateral ovary (n = 5). Five patients of them underwent reoperation and diagnosed as a mature teratoma, but one who had underwent a left salpingooophrectomy with right ovary cystectomy at initial operation was observed carefully. Teratomas were dominant in female patients and developed at various organs. Complete excision was needed for good prognosis. In case of immature teratoma, complete excision and appropriate chemotherapy according to grading can contribute to favorable results.

Background: Epidermoid cysts are benign tumors derived from the infundibular portion of hair follicles and thus have a flattened surface epithelium and keratohyaline granules. They can occur at any age but are most frequently reported in adults, and more often occur in men than women. Most epidermoid cyst operations are performed for cosmetic purposes, or to relieve inflammation. The definitive treatment is complete excision or destruction of the cyst. The aim of this study was to improve understanding of epidermoid cysts. Methods: We analyzed 432 cases of epidermoid cyst in 398 patients that underwent complete excision and biopsy between April 2001 and March 2020, according to patient age, patient gender, and lesion location. Results: From all epidermoid cyst excisions performed, 17.6% were for patients in their 40s and 50s, 16.8% for those in their 20s, 16.1% for those in their 30s, 14.6% for those aged 60 or older, 5.0% for teenagers, and 0.5% for those under 10 years. Cases of epidermoid cysts occurred at a men-to-women ratio of about 3:2, with 59.5% of cases in men and 40.5% in women. By lesion location, 65.0% of cases were on the face, 10.9% on the trunk, 7.9% on the scalp, 7.9% on the neck, 4.3% on lower extremities, 3.9% on upper extremities, and 0.2% on genitalia. On the face, 20.8% of cases were on the cheek, 12.7% on the periauricular area, 10.9% on the periorbital area, 6.0% on the frontal area, 5.6% on the mental area, 3.7% on the perioral area, 2.8% on the nasal area, and 2.5% on the temporal area. Conclusion: The proportion of women with epidermoid cysts was higher in our study than in previous studies. Moreover, the results showed that surgery has been on the rise in recent years, with facial surgery being the most common.

Two cases of the discrete membranous subaortic stenosis were experienced at the Department of Thoracic & Cardiovascular Surgery, National Medical Center, Seoul, Korea. Case I was 31 years old male with a history of aortic valve replacement[Ionescu-Shiley, 19mm] at the other hospital in 1980. Heart failure was noticed 6 years later. On cardiac catheterization, pressure gradient between left ventricle 4 aorta was 104 mmHg, but subvalvular aortic stenosis was not detected by preoperative 2-D echo <% left ventriculogram. Above case revealed stenoinsufficiency of the prosthetic valve. Under the diagnosis of the prosthetic valve failure, re-do aortic valve replacement[Bjork-Shiley, 23 mm] was done. During operation, the discrete membranous subaortic stenosis was incidentally found, and it was completely resected. So we thought that above discrete membranous subaortic stenosis was not detected at first operation, and it was progressed during 6 years, and accelerated the degeneration of the prosthetic valve. Case II was 20 years old female. Her complaints were exertional dyspnea, angina, syncope, which were aggravated since 5 years ago. 2-D echo <% left ventriculogram revealed the discrete membranous subaortic stenosis. Pressure gradient was 20 mmHg, but her symptoms were serious. Associated cardiac anomaly was the persistent left superior vena cava without connection with right superior vena cava. Complete excision of the membranous tissue was done. Post-operative pressure gradient between left ventricle & aorta was absent, and her complaints were nearly subsided. Both cases were type I according to the Newfeld classification of the discrete subvalvular aortic stenosis, and complete excision of the membranous tissue was done without myotomy or mymectomy. And short-term follow-up results[Case I:2 years, Case II: 1 ~ years] were good except soft systolic murmur[grade II/VI] at the aortic area in both cases.

Intraosseous hemangioma is a rare, benign vascular tumor of endothelial origin. It accounts for fewer than 1% of all hemangiomas, and very rarely occurs in the face. Intraosseous hemangioma usually presents as an asymptomatic lesion, but symptoms can occur due to the mass effect. The authors describe a case of intraosseous hemangioma of the zygoma with a review of the relevant literature. A 44-year-old man presented with a chief complaint of painless swelling on the left zygomatic region that had been slowly growing for the past year. On physical examination, a hard, non-movable mass in a deep layer was palpated. On computed tomography performed to evaluate its layers and extent, trabeculation was found inside the mass, but the lack of destruction of the surrounding bone suggested that the mass was benign. Complete surgical excision was performed under local anesthesia. After complete excision of the mass, slight erosions remained on the cortical bone of the zygoma, but because it was small enough not to cause a facial deformity such as depression or asymmetry, no additional reconstructive procedure was performed. There were no symptoms or recurrence during a 8-month follow-up period.

Aneurysmal bone cyst is a benign lesion of bone consisting of a septated, cystic cavity filled with non-endothelium-lined, blood-filled spaces. As it grows, expanding and destroying the affected part of the bone by direct compression, the lesion characteristically produces a prominent bulging of the affected bone, which eventually erodes the overlying cortex. Patients rarely complain of pain unless the cyst affects adjacent nerves or its expasion is great enough to impinge on the surrounding joints and soft tissue. Teeth adjacent to the cyst may be displaced, but usually remain vital. Development of the lesion in the craniofacial region is rare, and the mandible is more often affected than the maxilla. Complete surgical excision is used to treat aneurysmal bone cyst, with either curettage or composite resection. This is a case report of 49 years old female with aneurysmal bone cyst treated with surgical excision & DFDB graft.

Shoulder is a common site for calcific deposit and is frequently asymptomatic. There is a general agreement that calcific tendinitis should be initially treated nonoperatively and excision reserved for cases unresponsive to the conservative measures. There are several reports that arthroscopic excision of symptomatic calcific deposit is proved to be efficient in the calcific tendinitis refractory to nonoperative management. The results of arthroscopic treatment of chronic resistant calcific tendinitis of the shoulder in eleven patients were evaluated. Each patient had shoulder pain for more than one year prior to the arthroscopic surgery. The average age of the patients was 48 years(range 35-70). Arthroscopic calcium removal and subacromial bursectomy was performed in all patients. Arthroscopic acromioplasty was additionally done in four patients. The results turned out to be good in nine patients with full range of motion and complete pain relief. One patient with full motion and occcasional episodes of pain was satisfactory. One patient with persistent pain was unsatisfactory which converted to satisfactory six months later after subacromial injection. So we conclude that the arthroscopic treatment is a reasonable alternative in treatment of the chronic calcific tendinitis resistant to conservative treatment.

Complications of the mediastinal tumors and cysts are malignant change, infection, bleeding, local invasion and mass effect to heart, lung and other mediastinal structures. But early surgical excision and proper treatments bring patients to good clinical course and results. Therefore mediastinal tumors and cysts are surgically interesting diseases We report the analysis of the 58 cases of mediastinal tumors and cysts, experienced in the Department of Cardiothoracic Surgery of the Kosin Medical College from July 1979 to June 1989. The results were as follows ; Sex ratio of male to female to female was 1.3: 1. Range of age was from 11 to 64 years and mean age was 34.3 years. The thymomas were 14 cases[24%], the teratomas were 19 cases[33%o], the neurogenic tumors were 10 cases[17%], the cysts were 9 cases[15%], the carcinomas were 3 cases[5%], the thyroid tumor was 1 case[2%], the Castleman’s disease was 1 case[2%] and unclassified tumor was 1 case[2%]. Malignant tumors were 12 cases [21%] of the 58 cases. Most frequent symptom was chest pain and discomfort and relationship of symptom and malignancy was significant. Complete removal of tumor was performed on the 47 cases[92%] and partial excision was 3 cases[6%]. Inoperable cases were treated with anticancer chemotherapy and radiotherapy. Postoperative complications were wound infection, Homer’s syndrome, phrenic nerve palsy, mediastinal hematoma and pleurisy. There was no case of postoperative mortality and good clinical course in surgically completely resected cases.

Glomus tumor is uncommon tumor with an incidence of about 1% in soft tissue tumors and the single most common location is the subungual region of the finger. Many reports have emphasized that glomus tumors were difficult to diagnose and that the result of surgical removal was good, but nail deformity has received little attention. Most of authors removed the entire nail or partially splitted the nail to exposure the nail bed and tumor. Nobody reported whether nail deformity after operation was present or not. But, an abnormal nail is both a cosmetic and a functional problem in that catches on objects. In this study, our attention was postoperative nail deformity as well as the results of surgical removal. Seven patients(eight cases) who were diagnosed as a subungal glomus tumor in the hand were treated by surgical excision without removal of the nail and followed over twenty two months. And then we report on our experience with 8 cases of subungual glomus tumor which were successfully treated by complete excision without nail deformity.
