An 11 kg, 7-year-old male pug dog with lameness and tumor of the 2-3rd interdigital portion of the right forelimb was referred to the Veterinary Medical Center of the Tokyo University. On the clinical examination findings, the tumor size was $3{\times}3 cm but alopecia and necrosis were not found. On the radiological findings, a bone lysis was found in the phalanges of digit II of the right forelimb but pulmonary metastasis was not found. The mass was removed with metacarpal bone. Histopathological examination of the mass revealed highly differentiated hemangiopericytoma. Two weeks after the operation, the dog was irradiated by orthovoltage radiation. The source of irradiation was 300 kV, 4mA, 4Gy and a focal spot to skin distance of 40 cm using 1.0 Cu, 1.0Al filter. The radiation therapy was performed twice a week for 5 weeks. The dog showed no recurrence and no metastasis. It was thought that the surgery and radiation therapy treatment was quite a useful method to treat a canine heman-giopericytoma.

Purpose: Glomus tumors are uncommon benign neoplasms arising from the neuromyoarterial apparatus, usually seen in the nail bed of fingers. Most of this mass presents typical symptoms such as severe pain, point tenderness and hypersensitivity to cold like neuroma, gout or causalgia. Concerning about the origin, there were few written reports about extra-digit glomus tumor, especially that occurred in the skeletal muscule. Methods: A 48-year-old female complained of painful tender mass in her right calf aggravated several months ago. Her MRI and femoral angiogram showed a well defined hypervascular tumor such as hemagioma or hemagioendothelioma in the right calf. Surgical treatment was performed, and it proved glomus tumor in soleus muscle histologically. Results: After the operation, patient didn't complain of her symptoms any more and there was no evidence of recurrence during 1 year follow-up period. Conclusion: Authors have found only eight cases of intramuscular glomus tumor reported in the literature and present here the ninth case of an intramuscular glomus tumor and first case of soleus muscle.

Malignant tumors of the hand are very rare. Between 1989 and 1998, 17 patients with malignant tumors of the hand were evaluated for clinical features, prevalence, treatment and results. The mean age was 45 years and median duration of follow-up was 38 months. A painless mass was the most common symptom and the most common lesion was the digit. Fifteen cases of soft tissue and 2 cases of bone tumor were diagnosed. On pathology, soft tissue tumors were comprised of 8 cases of malignant melanoma, 2 cases of angiosarcoma and 1 case each of malignant fibrous histiocytoma, malignant peripheral nerve sheath tumor, extraskeletal chondrosarcoma, and squamous cell carcinoma. Bone tumors were metastatic tumors and each originated from the rectal cancer or lung cancer. Lymph node involvements were noted in 4 cases of malignant melanoma and 1 case of squamous cell carcinoma. Six cases of metacarpo-phalangeal joint disarticulation and 4 cases of phalanx amputation were performed. Wide excision, ray amputation and below-elbow amputation were also performed. Three cases expired due to metastasis and progression of the original lesion. Among the surviving 14 cases, a malignant melanoma had metastasis on the axillary lymph node and 13 cases showed no local recurrence or metastasis during the follow-up.

목적 : 건초에서 생긴 거대세포종은 수부에서 발생하는 종양 중 두 번째로 흔하나 절제술 후에 재발이 드물지 않으며 국내에서의 연구는 많지 않다. 이에, 저자들은 완관절부를 포함한 수부에 생기는 건초의 거대세포종의 임상적 특성과 수술적 치료후 결과를 분석하여 문헌고찰과 함께 보고하고자 한다. 대상 및 방법 : 1991년부터 1998년까지 수부에서 발생한 종물로 절제생검술을 시행받은 환자 중 조직병리학적으로 건초의 거대세포종으로 진단받은 총 38명, 41예에 대해 성별, 나이, 증상, 증상발현기, 종양이 발생한 부위, 발생한 건, 크기, 다발성 여부, 양측성 여부, 방사선학적 소견 및 골 침범, 재발여부 등에 대해 분석하였으며, 추시기간은 평균 13.1개월(5~40개월)이었다. 결과 : 38명 중 여자에서 29명으로 빈발하였고, 발생연령은 6세에서 66세까지 다양하였으나 50대에서 12례로 가장 호발하였으며 평균연령은 40.1세였다. 지배수지와 비지배수지의 발생경향은 비슷하였고(17례:21례), 모두 일측성이었다. 신전건(17례)보다 굴곡건(24례)에서 더 호발하였으며 증상발현기는 2개월에서 120개월(평균 23.4개월)이었다. 증상으로 대부분 무통성 종물을 호소하였으나, 5례에서 압통, 36례에서 운동장애, 5례에서 압박에 의한 신경증상을 호소하기도 하였다. 재발을 주소로 내원한 경우가 3례였다. 부위별 발생빈도는 수지에서 36례, 수장부에서 3례, 완관절부위 장측에서 2례 순으로 빈발하였으며, 수지별 발생빈도는 인지에서 14례(34%)로 가장 많았고, 엄지가 10례(24%), 중지는 9례, 환지는 5례, 소지는 3례의 빈도순을 보였다. 수지상 발생부위는 원위지골간 관절부 및 중위지골부에서 20례(48.8%), 근위지골 및 근위지골간 관절부가 9례, 중수지절관절부가 7례 순으로 호발하였다. 방사선학적 소견상 연부조직에 방사선 비투과적인 균일한 연부조직 음영을 보이고 있었고 3명에서 피질골 미란을 보였다. 37명에서 종양은 단발성 병변이었으나 이 중 4명에서 다엽상으로 넓게 분포하였고, 1명에서 다발성 병변을 보였다. 변연부 절제술후 재발된 경우가 2명으로 재발율은 5.1%였다. 결론 : 수부에서 발생한 건초의 거대 세포종은 호발조건으로 50대, 여성, 인지, 굴곡건, 수지 원위부를 추정해 볼 수 있었으며, 불완전한 변연부 절제술을 시행하거나, 수술 후 재발한 경우, 다발성, 다엽상 소견을 보인 경우 재발이 잘 되므로 이 경우 광범위 절제술이 필요할 것으로 사료된다.

Purpose: Pollicization typically involves surgical migration of the index finger to the position of the thumb. This procedure facilitates the conversion of a useless hand into a well-functioning one in patients who are not amenable to the toe-to-hand transfer. However, middle finger pollicization has been rarely reported. Materials and Methods: We reconstructed a thumb by immediate pollicization of the remnants of the middle finger in two patients who sustained a tumor and a trauma, respectively. The former, after cancer ablation was performed, has not been reported literally, and the latter involved free devitalized pollicization of the middle finger using a microsurgical anastomosis. The distal third extensor communis tendon was sutured to the proximal extensor pollicis longus tendon and the distal flexor digitorum superficialis and profundus were sutured to the proximal flexor pollicis longus. The abductor pollicis brevis tendon was sutured to the distal end of the first palmar interosseous muscle. Coaptation of the third digital nerve and the superficial radial nerve branch was performed. Results: Patients showed uneventful postoperative courses without complication such as infection or finger necrosis. Based on the principles of pollicization, a wide range of pinch and grasp movements was successfully restored. They were pleased with the functional and cosmetic results. Conclusion: Although the index finger has been the digit of choice for pollicization, we could also use the middle finger on specific occasions. This procedure provides an excellent option for the reconstruction of a mutilated thumb and could be performed advantageously in a single step.

Background Primary malignant tumors of the hand, although unusual, may present varied and often complex clinical problems. The main treatment modality of skin cancer of the hand has changed. Methods We retrospectively reviewed the medical records of 43 patients who underwent surgery for malignant skin tumors of the hand during an 18-year period, from September 1994 to February 2012. The characteristics of the tumor, methods of reconstruction, and long-term results were reviewed. Results We had 43 patients with 27 melanomas, 14 squamous cell carcinomas, and 2 sarcomas. Their ages ranged from 19 to 74 years (mean, $53.4{\pm}14.5$ years), from 46 to 79 years (mean, $59.7{\pm}9.6$ years), and from 15 to 43 years (mean, $29{\pm}19.8$ years), respectively. Thirty-four cases occurred on the fingertip (16 of those cases on the thumb), 5 cases occurred on the palm, and 4 cases on the dorsum of the hand. Amputation was most frequently used in early cases, but recently, tissue-sparing excision has been performed frequently. The incidence of local recurrence was 3 cases and distant metastasis was 1 case, and the 5-year survival rate was 100%, except in 4 cases due to follow-up loss. Conclusions The principles of treatment-to be curative and to preserve function and appearance-are important points. "Preservative surgery" preserves function and cosmesis of the involved finger or hand dorsum or palm. Preservative surgery not only emphasizes less resection and surgery of a smaller scale, but also optimal reconstruction of the soft tissue defect of the digit.

Objectives : To investigate the cognitive functions of pediatric cancer patients and to test the hypotheses that the impairment of processing speed and working memory are more prevalent in children with medulloblastoma (MBL) compared to children with neuroblastoma (NBL). Methods : We gave the Korean version of the Wechsler Intelligent Scale for Children-III to 21 children with MBL and 24 children with NBL during outpatient follow-up after the treatment was completed. Results : Children with MBL showed below average performance across most of the sub-tests. The full scale IQ, verbal IQ, and performance IQ of children with MBL were significantly lower than those of children with NBL. There were significant differences between two groups in coding and Digit Span subtest scores. Children with MBL performed especially poorly in the coding subtest. Conclusion : These findings support previous reports of generally low IQ and the dysfunction of processing speed and working memory among children with MBL, a kind of central nervous system tumor. Further investigation is needed to determine how the deficit of processing speed and working memory affect neurocognitive development and general intelligent functions.
