Mesenchymal chondrosarcoma is a rare tumor that is more common in young people; it is an uncommon type of chondrosarcoma with a poor prognosis. In two-thirds of cases, it affects the bone, especially the spine. However, parts of the body other than the skeletal system are occasionally involved. These rarer types have a worse prognosis, with a high likelihood of metastasis and death. Due to the possible misdiagnosis of mesenchymal chondrosarcoma, the integrated use of imaging, immunohistochemistry, and pathology can be helpful.

Various studies have been done in medical service area but they have just focused on the examination of the relationships between cause and effect variables. This study, thus, empirically analyzed qualitative data regarding medical service problems using word cloud technique. The major results of the paper are as follows. The data reveal ten sources in medical service - forced treatment, excess inspection, misdiagnosis, carelessness, inexperienced service, waiting for emergency, reservation problem, unkindness, process problem, and inconvenience. Major words in the category of irrecoverable service failure are misdiagnosis, careless treatment, and inexperienced service whereas those in recoverable service failure are unkind attitude and negative experience in reservation system. Those who experienced a medical service problem are usually engaged in a public act and they make public protests and legal action against very severe problems. The conclusion of this study also suggests a summary, implication, and agenda of the research.

Purpose: The schwannoma is a benign peripheral nerve tumor arising from the Schwann cell of the nerve sheath. Only 2-8% of schwannomas arise in the hand and wrist. Misdiagnosis is frequent such as ganglion and neurofibroma. This article documents and clarifies the clinical features of schwannomas arising in the hand and wrist, and emphasizes importance of differential diagnosis and meticulous surgical extirpation under magnification. Methods: The author reviewed clinical features of 15 patients with pathologic final diagnosis of schwannoma developed in hand and wrist during the last 12 years from 1998 through 2009. The review included the sex, age of onset, duration, preoperative diagnosis, location, involved nerve, preoperative symptoms and. Postoperative sequelae after surgical extirpation of the lesion with magnification, or without magnification of the surgical fields. Results: The chief complaints were slow growing firm mass in all patients, and followed by pain in 40%, and paresthesia in 40% respectively. The lesions were developed solitarily in 14 patients (93%). The postoperative pathologic diagnosis and preoperative diagnosis were coincided with only in 6 patients (40%). Other preoperative diagnosis were soft tissue tumor in 4 patient (26.6%), and ganglion in 3 patients (20%), and neurofibroma in 2 patients (13%). In all patients who were undergone surgical excision under the fields of magnification, all symptoms were subsided without any sequelae. Meanwhile muscle weakness, paresthesia, hypoesthesia and /or accidental nerve resection developed after surgical excision with naked eye. Conclusion: Schwannoma in hand most commonly appears as a slow growing solitary mass with pain or paresthesia. The chance of preoperative misdiagnosis was 60% in this series. To provide good prognosis and less sequelae, careful and elaborate diagnostic efforts and meticulous surgical excision under the magnification are necessary in management of schwannoma.

In this study, I proposed of an engineering analysis methods due to interference effect within the cyst by ultrasound in the renal ultrasonography. Experimental results, the human can not be found to distinguish interference caused by the ultrasonic echoes within the cyst. The proposed method is used, then in the cyst appears insignificant signal can distinguish the difference. Thus, the misdiagnosis can be prevented in advance.

Visceral leishmaniasis or kala-azar is an endemic parasitic disease in some parts of the world which is characterized by fever, splenomegaly, and pancytopenia in most of the cases. Herein we report an 11 month-old male infant with diagnosis of kala-azar who presented with pallor, hepatosplenomegaly, failure to gain weight, and no history of fever. Surprisingly, fever started after beginning of meglumine antimoniate treatment in this patient. As far as we are aware of, this is a rare presentation of visceral leishmaniasis. Therefore, clinicians especially in endemic areas are highly recommended to include kala-azar among differential diagnosis of unexplained anemia without fever to prevent misdiagnosis of this potentially fatal, but treatable condition.

Burkitt's lymphoma is a malignant monoclonal proliferation of early B-lymphocyte. Since Burkitt's lymphoma is a highly aggressive disease, early detection is a crucial. This disease often involves jaw and mandibular mass or swelling may also be seen, but in the early phase of Burkitt's lymphoma these symptoms cannot be observed. A rare case of Burkitt's lymphoma without any mandibular mass and the general symptoms was present. The excruciating toothache led the patient to visit the dental clinic and misdiagnosis of chronic periodontal abscess was made initially. Dentists should consider the oral manifestations of systemic disease when the multiple periodontal ligament space widening is observed and the dental treatment for mimicking odontogenic pain has no effect.

Radiological criteria such as smooth, sharply defined interface, obtuse angles between lesion and lung and intimate effect on mediastinal contents were usually used to differentiate mediastinal lesion from parenchymal lung lesion. Recently, we experienced a 60-year-old female presenting with anterior mediastinal mass with cavitation. Grossly it was proven to be peripheral lung cancer adjacent to mediastinum and microscopically it was squamous cell carcinoma. The gross pathological findings of surgical specimen were very well correlated with radiological findings. The unique location such as lung periphery and attachment to mediastinum led us to misdiagnosis of anterior mediastinal mass such as germ-cell tumor and neurogenic tumor.

Actinomycosis is a chronic suppurative granulomatous disease due to Actinomyces israelii characterized by multiple abscess and sinus tract formation with dense fibrous scarring. This disease, especially thoracic infection, is very rare in Korea so we are not famiIliar with to make diagnosis and treatment. Otherwise the unspecificity of the clinical symptoms and the lack of adequate examination recedure (as anaerobic fungus culture) are the causes of misdiagnosis. Thoracic actinomycosis is very similar to chronic infectious disease of the lung and chest or thoracic neoplasm. Recently we experienced a case of thoracic actinomycosis (bronchopulmonary) which had been confused with chronic lung abscess and pathologically confirmed as broncho-pulmonary actinomycosis. The purpose of this report is to review our experience more thorouly to enhance consideration of Artinomycosis.

Fibrodysplasia ossificans progressiva is a very rare genetic disorder, but is possible to diagnose with mass on neck or scalp in early neonate or child and accompanying characteristic congenital malformation of great toe. But because inappropriate treatment and complications from misdiagnosis may aggravate the progress of the disease, so the disorder require careful inspection for accurate diagnosis. We describe a case that was misdiagnosed properly and treated inappropriately and the natural history of the disease in adult.

A spinal epidural hemangioma is rare. In this case, a 51 year-old female patient had low back pain and right thigh numbness. She was initially misdiagnosed as having a ruptured disc with possible sequestration of granulation tissue formation due to the limited number of spinal epidural hemangiomas and little-known radiological findings. Because there are no effective diagnostic tools to verify the hemangioma, more effort should be put into preoperative imaging tests to avoid misdiagnosis and poor decisions).
