Schwannomas, which originate from Schwann cells in the peripheral nervous system, are slowg-rowing and uncommon benign tumors. Most schwannomas (90%) occur in isolation, and multiple occurrences are a characteristic feature of neurofibromas. Schwannomas of the nose and nasal tip are particularly unusual. Although a few cases of schwannomas of the sinusoidal tract and nasal septum have been reported, schwannomas arising from the nasal dorsum area and tip are extremely rare. Sensory abnormalities are also a very rare symptom. We excised a schwannoma on the nasal dorsum through direct incision and a schwannoma on the nasal tip through open rhinoplasty. No postoperative complications involving recurrence, hematoma, or infection occurred. The possibility of neurological changes should be considered in cases of an abnormality in the peripheral nervous system. Schwannoma must be kept in mind as a possible cause of neurological changes localized to a specific dermatome, and should always be considered in the differential diagnosis of a mass on the nose.

Multicentric Castleman disease (MCD) is an uncommon systemic lymphoproliferative disorder that may cause multiple organ damage. Castleman disease-associated diffuse parenchymal lung disease (DPLD) has not been well studied. A 32-year-old man was referred to our hospital for progressive generalized weakness, light-headedness, and dyspnea on exertion for more than one year. Laboratory evaluations showed profound anemia, an elevated erythrocyte sedimentation rate, and an increased C-reactive protein level with polyclonal hypergammaglobulinemia. Chest radiography, computed tomography (CT), and positron emission tomography-CT scan demonstrated diffuse lung infiltration with multiple cystic lesions and multiple lymphadenopathy. In addition to these clinical laboratory findings, bone marrow, lung, and lymph node biopsies confirmed the diagnosis of idiopathic MCD (iMCD). Siltuximab, an interleukin-6 inhibitor, and glucocorticoid therapy were initiated. The patient has been tolerating the treatment well and had no disease progression or any complications in 4 years. Herein, we report this case of human herpesvirus-8-negative iMCD-associated DPLD accompanied by multiple cystic lesions, multiple lymphadenopathy, and polyclonal hypergammaglobulinemia with elevated immunoglobulin G (IgG) and IgG4 levels. We recommend a close evaluation of MCD in cases of DPLD with hypergammaglobulinemia.

Pleuroperitoneal communication (PPC) is a rare mechanical complication of peritoneal dialysis (PD), which causes dialysate to move from the peritoneal cavity to the pleural cavity, resulting in pleural effusion. Typically, PPC is discovered through pleural effusion in PD patients who are not in volume overload status. A unique characteristic of the pleural effusion caused by PPC is that it is not resolved by increasing ultrafiltration by dialysis. In this report, we present a 7-year-old girl with PD after birth with the history of various infectious PD-related complications, presenting with fever ongoing for 6 months. PPC-associated pleuritis was suspected as the cause of fever, which eventually developed after long-term PD and induced complicated pleural effusion, lung inflammation, and prolonged fever for 6 months.

Uterine rupture is uncommon in small animals and can be caused by trauma, infection, dead fetus, or inappropriate obstetric techniques. A 4-year-old, intact female mixed-breed dog weighing 3 kg presented for elective ovariohysterectomy with a history of a motor vehicle accident two months previously. The patient showed no clinical signs of uterine abnormalities or evidence of pregnancy during physical examination. Clinical examinations, radiography, and ultrasonography revealed no significant findings. During ovariohysterectomy, a completely transected left uterine horn and dome-shaped ends were identified. The uterine layers were everted such that the endometrium could be seen outside the uterine horn. The dog recovered without post-operative complications and was discharged the following day. This report describes a rare case of an asymptomatic uterine rupture caused by trauma in a non-gravid dog.

Phlebotomy, a therapeutic method of bloodletting typically performed using a needle, has a traditional technique known as "Fasd." In this method, blood is extracted by creating a longitudinal incision on a vein (3-5 mm) with a surgical scalpel blade, usually blade No. 11. Due to the incision in the vessel wall, establishing hemostasis is more challenging compared to conventional methods. Hemostasis is usually achieved within minutes after Fasd. We present a case highlighting an uncommon yet significant complication of traditional phlebotomy. A 55-year-old man with no prior medical conditions underwent traditional phlebotomy at an academic traditional medicine clinic. Senior MD-PhD students in Iranian Traditional Medicine, under professor supervision, performed Fasd. A sterile scalpel blade No. 11 was used to create a longitudinal incision of approximately 4 mm on the patient's median basilic vein in the right hand. After removing 400 cc of blood, a pressure dressing was applied to the incision site. Despite attempts such as hand elevation, ice pack application, prolonged direct pressure, and tight elastic bandaging, bleeding from the incision persisted. After an hour of supportive therapy, hemostasis was eventually achieved within a few minutes using burnt cotton dressing (a traditional method for blood hemostasis). Following intravenous hydration, the patient was discharged in stable condition and reported no issues during the one-month follow-up. The traditional phlebotomy (Fasd) carries the risk of serious complications, including uncontrolled and prolonged bleeding. Further research on the efficacy and safety of burnt cotton dressing for controlling hemostasis is recommended.

배경: 자연성 종격동 기종은 드문 질환으로 세계적으로 보고된 환자도 적다. 주로 젊은 남자에서 발병하며 양성의 자연 치유 경과의 질환으로 어떤 특별한 이유 없이 일어난다. 폐기포 파열을 일으키는 흉강내 압력 변화 이후 나타나게 된다. 두 병원의 임상 경험을 분석하여 적정한 치료에 도움이 되고자 한다. 대상 및 방법: 후향적으로 2003년 3월부터 2010년 8월까지 자연성 종격동 기종 환자들을 연구하였다. 결과: 24명의 환자가 자연성 종격동 기종으로 진단되었다. 이들 24명의 환자는 18명의 남자와 6명의 여자로 구성되었고, 평균 나이는 18.9세였다(범위 10~33살). 초기 주요 증상은 흉부 통증(79.2%), 이후 통증(62.5%), 피하 기종(4 1.7%)이었고 유발 인자로 운동(16.7%), 기침(12.5%), 구토(12.5%) 등이었고 유발 인자가 없는 경우가 54.2%였다. 모든 환자에서 흉부 단순 촬영과 단층 촬영이 이루어졌으며, 25% 환자에서 진단을 위해 단층 촬영이 필요하였다. 백혈구 수치와 C반응 단백(CRP)가 측정되었는데 초기 평균 수치는 각각 $9,790{\pm}3,240/{\mu}L$와 $1.31{\pm}1.71mg/dL$, 최종 평균 수치는 $5,440{\pm}1,665/{\mu}L$와 $0.72{\pm}0.73mg/dL$이었다. 23명의 환자가 입원하였으며(평균 $5.0{\pm}1.8$일) 증상은 자연 치유되었으며 합병증은 없었다. 결론: 자연성 종격동 기종은 약한 염증성 증세를 보이는 양성 질환이며 종종 흉부 또는 인후 통증을 나타낸다. 바람직하지 못한 결과를 방지하기 위하여 비침습적인 검사로 이차성 원인이 배제되어야 한다. 합병증과 재발이 거의 없는 관계로 증상에 따라 외래 진료나 단기적인 입원이 합당하다고 하겠다.

Purpose: Severe pancreaticoduodenal injuries are relatively uncommon, but may result in high morbidity and mortality, especially when management is not optimal, and determining the appropriate treatment is often difficult. The objective of this study was to review our experience and to evaluate the role of a pancreaticoduodenectomy (PD) in treatment of pancreaticoduodenal injuries. Methods: We performed a retrospective review of 16 patients who underwent an emergency PD at our hospital for severe pancreaticoduodenal injury from 1990 to 2011. Demographic data, clinical manifestations, mechanism and severity of the injury, associated injuries, postoperative complications and outcomes were reviewed. Results: The mean age of the 16 patients was $45{\pm}12years$ ($mean{\pm}standard$ deviation), and 15(93.8%) patients were male. All patients underwent an explorative laparotomy after a diagnosis using abdominal computed tomography. Almost all patients were classified as AAST grade higher than III. Thirteen(83.3%) of the 16 patients presented with blunt injuries; none presented with a penetrating injury. Only one(6.3%) patients had a combined major vascular injury. Fifteen patients underwent a standard Whipple's operation, and 1 patient underwent a pylorus-preserving pancreaticoduodenectomy. Two of the 16 patients required an initial damage-control procedure; then, a PD was performed. The most common associated injured organs were the small bowel mesentery(12, 75%) and the liver(7, 43.8%). Complications were intraabdominal abscess(50%), delayed gastric emptying(37.5%), postoperative pancreatic fistula(31.5%), and postoperative hemorrhage (12.5%). No mortalities occurred after the PD. Conclusion: Although the postoperative morbidity rate is relatively higher, an emergency PD can be perform safely without mortality for severe pancreaticoduodenal injuries. Therefore, an emergency PD should be considered as a life-saving procedure applicable to patients with unreconstructable pancreaticoduodenal injuries, provided that is performed by an experienced hepatobiliary surgeon and the patient is hemodynamically stable.

Epithelioid hemangioendothelioma (EHE) is a well-differentiated and rare vascular tumor. Systemic metastases are uncommon. Herein, we present a patient with skin metastasis of pulmonary EHE (PEH) that was treated by wide excision. A 76-year-old male was evaluated due to pulmonary thromboembolism and a solitary pulmonary nodule. A biopsy was performed and pathological examination of the mass confirmed EHE. No metastasis was observed. The patient returned to care approximately two years later due to a painful nodule in the right lower leg. A skin biopsy showed metastatic EHE from the lung. We used a safety margin of 1 cm based on clinical experience, because no prior case had been reported regarding the resection margin appropriate for primary cutaneous EHE and skin metastases of PEH. At four months after surgery, the patient recovered without complications or recurrence. Skin metastasis of PEH is extremely rare, and only two cases have been reported in the literature. In this case, we report a rare case of PEH with histologically diagnosed skin metastasis that was successfully treated by curative resection. It is expected that this case report will provide a helpful contribution to the extant data regarding PEH metastases.
