  • Angiosarcoma of the brain, either primary or metastatic is extremely rare. Moreover, angiosarcoma metastazing to the brain is also highly unlike to occur when comparing with metastases to the other organs. Thus, an ideal treatment strategy has not been established. A 67-year-old man with past surgical history of a scalp angiosarcoma underwent surgical resection of intracranial invasion. Because of wide scalp flap excision and resultant poor vascularity of the scalp flap, additional radiation was not provided. Because adjuvant therapy is impossible due to poor scalp condition, more careful but ample resection of the primary lesion is essential to conduct initial operation.

  • The authors describe an anaplastic oligodendroglioma of the cerebellum which is distinctly uncommon. The patient presented with sudden onset of decreased consciousness associated with hemorrhage in the cerebellum, which appeared to origin from a vascular malformation or a tumor on a initial computed tomography (CT) scan. Subsequent magnetic resonance (MR) imaging suggested a high grade glioma with abundant vascularity in the right cerebellum. The histological examination revealed the findings compatible with those of an anaplastic oligodendroglioma. A complicated clinical course had led him to a poor outcome.

  • Hemangioblastomas in the pituitary stalk are especially rare. Most pituitary stalk hemangioblastomas reported in the literature were associated with von Hippel-Lindau (VHL) disease. Here, we report only the 3rd case of sporadic pituitary stalk hemangioblastoma diagnosed in a 60-year-old woman. Despite the danger of potential complications due to excessive vascularity or proximity to important neural structures, the tumor in our case was successfully removed while preserving pituitary function. In this case, complete surgical excision was shown to be an effective treatment option for symptomatic pituitary stalk hemangioblastoma, and we suggest careful evaluation of any highly enhancing mass with a signal void in the pituitary stalk preoperatively, even if no VHL disease is evident.

  • Portosystemic shunts in 3 Dogs with respiratory sign of cough and with dementia signs characterized by hypersensitivity, salivation, and seizure were diagnosed at veterinary teaching hospital of Seoul National University. In radiographs, microhepatica was observed. In abdominal ultrasonography, abnormal intrahepatic connections between the portal vein and the systemic vessels and tortuous vascularity were found. There was no complication such as ammonium urate urolith in kidney or urinary bladder, These dogs were treated with medicine and protein-restricted diet.

  • Ankle arthrodesis has been considered to be the standard operative treatment for end-stage ankle arthritis, nevertheless currently increasing arthroplasty. Indication for arthrodesis is painful ankle from global arthrosis regardless of the etiology. But it is hard to be carried out in the several circumstance such as infection states, poor vascularity, severe diabetes, prematurity, etc. So thorough evaluation should be done before the surgery, including adjacent joints status. The ideal position for fusion is neutral in flexion, functional valgus, and slightly external rotation. Methods of arthrodesis would be largely divided into two categories as in situ fixation and realignment procedure. The lateral and anterior longitudinal approaches are two common procedures, and fixation modalities are also variable. The long-term results of arthrodesis have been reported. Even the close follow-up have shown subsequent degeneration of adjacent joints, benefits such as reliable pain loss, easy correctability for deformity, and improved functional status with considerable durability can be expected in the most patients.

  • Rheumatoid arthritis (RA) is one of the most typical rheumatic diseases, and is characterized by chronic inflammation, cartilage destruction and joint deformity [1,2]. During this process, profound hypertrophic changes of the synovium with infiltration of immune cells, increased vascularity, and hyperplasia result in the formation of a synovial pannus that invades cartilage and bone [3]. In early stages of RA, the synovial membrane begins to invade the cartilage. In established RA, the synovial membrane becomes transformed into inflammatory tissue, the pannus (Fig. 1). The cell types that occupy cartilage-pannus junctions include synovial macrophages, fibroblasts, mast cells, polymorphonuclear lymphocytes (PMNs), and displaced, probably differentiated condrocytes [4-6]. Recent studies of rheumatoid synovial tissue have demonstrated localized accumulations of mast cells and evidence of their activation/degranulation[7].

  • Flap thinning is a procedure for making a thick flap thinner. This procedure does more than simply fill in the defected area, and it is better for reconstructing the area both functionally and aesthetically. However, because flap thinning is a rather blind procedure, it may have harmful effects on flap vascularity. Therefore, the vasculature of a flap must be understood before performing flap thinning. This paper analyzes the basic anatomy underlying flap thinning based on the previous anatomic study that categorized flaps into 6 types by their vascular structures. This paper also reviews specific studies of frequently practiced flap procedures (deep inferior epigastric artery perforator flap, thoracodorsal artery perforator flap, and anterolateral thigh flap) and presents important precautions for flap thinning procedures. Finally, this paper briefly examines the axiality of the subdermal plexus, which needs to be taken into account when performing flap thinning.

  • Castleman's disease is a relatively rate disorder of lymphoid tissue and poorly understood etiology. The disease may occur anywhere along the lymphatic chain, but is most commonly found as a solitary mass in the mediastinum. The hyaline vascular type represents 91% of Castlemen's disease, and these are most often discovered in the asymptomatic patient on routine chest film. Patients with the plasma cell type often exhibit systemic symptoms, including fever, night sweats, anemia, and hypergammaglobulinemia. Surgical excision effects cure, although resection of the hyaline vascular type may be associated with significant hemprrage owing to extreme vascularity. We recently experienced a case of hyaline vascular type Castleman's disease which was treated by surgical resection through the anterior mini-thoracotomy, and report with its review.

  • Purpose. Hypertrophic scarring and depression are the principal problems of bum rehabilitation. This study was done to verify the effects of skin rehabilitation massage therapy (SRMT) on pruritus, skin status, and depression for Korean bum survivors. Methods. A pretest - posttest design using a nonequivalent control group was applied to examine the effects of SRMT for 3 months in a group of 18 bum survivors. The major dependent variables - including pruritus, objective and subjective scar status, and depression - were measured at the beginning and at the end of the therapy to examine the effects of SRMT. Results. Bum survivors receiving SRMT showed reduced pruritus, improved skin status, and depression. The remaining scar also showed improvement in skin pigmentation, pliability, vascularity, and height (compared to the surrounding skin) as measured on the Vancouver Scar Scale (VSS). Conclusions. The findings demonstrate that SRMT for bum survivors may improve their scars both objectively and subjectively, and also reduce pruritus and depression.

  • Performing rhinoplasty using filler injections, which improve facial wrinkles or soft tissues, is relatively inexpensive. However, intravascular filler injections can cause severe complications, such as skin necrosis and visual loss. We describe a case of blepharoptosis and skin necrosis caused by augmentation rhinoplasty and we discuss the patient's clinical progress. We describe the case of a 25-year-old female patient who experienced severe pain, blepharoptosis, and decreased visual acuity immediately after receiving a filler injection. Our case suggests that surgeons should be aware of nasal vascularity before performing an operation, and that they should avoid injecting fillers at a high pressure and/or in excessive amounts. Additionally, filler injections should be stopped if the patient complains of severe pain, and appropriate measures should be taken to prevent complications caused by intravascular filler injections.
