  • Atypical fibroxanthoma(AFX) is a tumor that occurs as a solitary and ulcerative nodule on actinically damaged or radiation damaged skin of the head and neck in the elderly. AFX is a pleomorphic spindle cell neoplasm of the dermis, which is a clinically benign reactive lesion despite of apparently malignant histologic features. We report a case of AFX which developed on the nasal root area of a 23-year-old man. This case is very unusual in terms of site(less sun-damaged area), overlying skin feature(grossly normal skin) and age(too young). This tumor was completely removed with surgical excision and remained free of recurrence for a period of about 1 year follow-up.

  • Aspiration biopsy cytology is a convenient, easy and non-invasive method for diagnosis of tumors. The results and cytologic features of carcinoma in various organs have been reported frequently, however, those of soft tissue sarcoma are relatively rare to find. Here we describe fine needle aspiration cytologic features of various soft tissue sarcomas and discuss cytologic differential points. The material is 6 cases of soft tissue sarcoma that were confirmed by histologic examination. They are composed of 2 cases of dermatofibrosarcoma protuberans and one case of malignant fibrous histiocytoma, synovial sarcoma, alveolar soft pan sarcoma, and malignant schwannoma respectively.

  • We experienced 3 cases of continuous caudal block. The first case had suffered from severe pain of the external genitalis after urethral injury from a car accident and this was controlled by continuous caudal block. The other 2 cases were a metastaric malignant tumor of the lumbar vertebra from cancer of the cervix and histiocytoma of the breast, and both had suffered from intractable pain of the lower extremity. But lumbar epidural block was impossible because of radiation fibrosis and previous operation scar of the spine. So a continuous caudal block was performed and the pain was controlled effectively. The longest duration was 50 days and there were no problems related catheter indwelling. Pain in the area of the lumbar and sacral nerve distribution can be controlled by continuous caudal block. Here in we reported 3 cases and reviewed the literature.

  • 67세 남자환자가 하지의 악성섬유조직구종으로 진단받고 광범위 절제술 후 방사선치료를 받는 동안 연쇄구균독소충격증후군이 발생하여 그 예를 소개하고자 한다. 환자는 수술 후 증감하는 부종이 있어 약 1개월간 비스테로이드소염제를 복용하였다. 환자는 C형 간염보균자였으며, 당뇨, 고혈압의 과거력이 있었다. 환자는 수술 후 방사선치료를 계획하여, 주 5회 조사하여 32.4 Gy를 치료받았다. 이틀간의 주말 치료중단이후 갑자기 방사선치료 받은 우측 대퇴부에 홍반성 염증이 발생하였고, 열, 오한, 소변감소증이 동반되었다. 환자는 즉시 감염내과에 의뢰되었고, 독소충격증후군이 의심되어 즉시 입원하였다. 입원당시 환자는 저혈압, 소변감소증, 변비, 비정상적인 신기능 및 간기능 소견을 보였다. 환자의 혈액 배양 결과 스트렙토콕쿠스 피오게네스균(Streptococcus pyogenes)이 검출되었다. 환자는 연쇄구균독소충격증후군으로 진단받고 적절한 항생제치료와 수액공급을 받았다. 연쇄구균독소충격증후군은 생명을 위협하는 종양학적 응급상황으로 즉각적인 처치가 필요하다. 본 예의 환자는 C형 간염보균, 수술 후 증감되는 부종, 지속적인 비스테로이드소염제 복용과 방사선치료가 연쇄구균독소충격증후군을 일으킨 인자들로 생각되어진다.

  • Liposarcoma is the second most common sarcoma of the adult life, next to malignant fibrous histiocytoma. Liposarcoma in larynx and hypopharynx is extremely rare. The symptoms are variable, but it has a clinical importance because they can cause unpredictable airway obstruction, particularly during the induction of general anesthesia. A 79-year-old male patient was referred to our department for mild airway obstruction and throat discomfort. Neck CT scan showed a mass within both postcricoid area and pyriform sinus. The mass was removed via laryngeal microsurgery. In this article, we report a case of liposarcoma of the posterior wall of hypopharynx with a review of the related literature.

  • CT findings of proven 25 malignant tumors of the maxillary sinus were retrospectively analyzed to be of help in the diagnosis and treatment. The results were follows: 1. Average age was 54 years old, and eighteen were males and seven were females with a ratio of 2.6:1 2. The most common histopathologic feature was squamous cell carcinoma (19 cases) and others were two cases of adenoid cystic carcinoma, one case of malignant fibrous histiocytoma, mucoepidermoid tumor, histiocytic lymphoma, unidentified malignant tumor. 3. CT findings were sinus opacificaqtion (4%), soft tissue mass (92%), low densities within soft tissue mass (44.%), air densities within soft tissue mass (24%), osteosclerosis (4%), bone destruction (92%), bone displacement (32%), fat plane obliteration (76%). 4. CT in the malignant maxillary sinus tumors approved the value in evaluation of tumor extension to nasal cavity, ethmoid sinus, orbit, infratemporal fossa, pterygopalatine fossa, pterygoid fossa, pterygoid muscle, cheek skin and intracranial cavity. 5. Twenty four cases (96%) were stage Ⅲ, stage Ⅳ according to AJCC TNM classification. 6. Bone findings were destruction, displacement, sclerosis and most frequent site of bone destruction was the medial wall of the antrum(92%). 7. Tumor growth pattern showed destructive pattern in 18 cases(72%), and squamous cell carcinoma showed destructive pattern. (P<0.05)

  • Myxofibrosarcoma, also known as a myxoid variant of a malignant fibrous histiocytoma (MFH), is one of the most common sarcomas in the extremities of elderly people. The lesion is characterized by a high frequency of local recurrence but is uncommon in the head and neck regions. Low-grade myxofibrosarcoma, which is commonly misinterpreted as being benign, has a tendency for histological and biological progression in local recurrences, highlighting the importance of an accurate diagnosis and wide surgical excision of the primary lesion. We report a rare case of low-grade myxofibrosarcoma of the mandible located in the left mandibular body and angle area. The tumor was first diagnosed as a myxofibroma and was resected initially. After the final biopsy the patient underwent combined chemo-radiotherapy. The progress of the patent was uneventful until the one year follow up.

  • Purpose: Evaluation of results of free flap as a method of reconstruction in soft tissue defect after wide excision of soft tissue tumor of extremity. Materials and Methods: From 2000 through 2007, 11 patients received free flap surgery for soft tissue defect after wide excision operation for soft tissue tumor of limbs. Four cases were upper extremities and seven were lower extremities. Four subjects were diagnosed as squamous cell carcinoma, three as malignant melanoma, two as synovial sarcoma and one as malignant fibrous histiocytoma and alveolar soft part sarcoma. Donor sites of free flap varied with anterolateral thigh flaps in six cases, latissimus dorsi flaps in four, reverse forearm flap in one. By the method of doppler ultrasound, venous circulation was evaluated for the survival of each flap on the third, fifth and seventh day respectively after the operation. Results: 10 of 11 free flaps were successfully survived. Necrosis of free flaps in 1 cases occurred in case of anterolateral thigh flap. Conclusion: Free flap can be a useful method for reconstruction of soft tissue defect after wide excision of soft tissue sarcoma of extremity.

  • Authors enumerate various malignant and benign cases which showed soft tissue uptake of $^{99m}Tc-MDP$. We hope it might be a help in understanding and interpreting bone scans. Among 10,361 $^{99m}Tc-MDP$ bone scans underwent from April, 1981 to March, 1986, 344 (3.3%) showed abnormal soft tissue uptake, which included 126 malignancies, 5 benign tumors, and 153 nontumorous diseases. Neuroblastoma(23.3%) and malignant fibrous histiocytoma(22.2%) showed highest positive uptake rate among various malignancies. We also illustrated typical cases according to possible mechanisms.
