Progressive multifocal leukoencephalopathy(PML) is a fatal demyelinating disease that occurs in immunocompromised hosts. We report a case of PML that developed in patient with T cell lymphoma of head and neck. During chemotherapy for lymphoma, she was confused and had memory impairment. A magnetic resonance imaging of the brain revealed confluent signal change at white matter of the frontal lobe, insula, and anterior limb and genu of internal capsule. The lesion was confirmed with brain biopsy and the histopathological finding was compatible with PML.

Gastrointestinal stromal tumors (GISTs) are the most common primary mesenchymal neoplasms of the gastrointestinal tract and usually appear as a well-circumscribed mass. However, it may be difficult to confirm the extent of the disease for some GISTs. A 70-year-old asymptomatic female presented for a regular physical exam. An esophagogastroduodenoscopy showed a 2.0 cm protruding mass on the gastric fundus. Endoscopic ultrasound revealed an ill-defined heterogenous hypoechoic lesion ($3.0{\times}1.5cm$). A computed tomography (CT) scan demonstrated a 4.5 cm multifocal calcified mass at the gastric body as well as at the gastric fundus. Laparoscopic gastric wedge resection was performed according to the extent of multifocal calcifications that are shown on the CT. Intraoperative specimen mammography and intraoperative biopsy might be helpful to obtain a tumor-free margin. Final pathologic diagnosis was an intermediate risk GIST in multilobular form. In patients with diffuse multifocal calcifications in the stomach, the possibility of GIST should be considered.

Chronic recurrent multifocal osteomyelitis (CRMO) is one of the most severe form of chronic non-bacterial osteomyelitis (CNO), which could result in bone and related tissue damage. This autoinflammatory bone disorder (ABD) is very difficult for its clinical diagnosis because of no diagnostic criteria or biomarkers. CRMO in the jaw must be suspected in the differential diagnosis of chronic and recurrent bone pain in the jaw, and a bone biopsy should be considered in chronic and relapsing bone pain with swelling that is unresponsive to treatment. The early diagnosis of CRMO in the jaw will prevent unnecessary and prolonged antibiotic usage or unnecessary surgical intervention. The updated researches for the identification of genetic and molecular alterations in CNO/CRMO should be studied more for its correct pathophysiological causes and proper treatment guidelines. Although our trial consisted of reporting items from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), there are very few articles of randomized controlled trials. This article was summarized based on the author's diverse clinical experiences. This paper reviews the clinical presentation of CNO/CRMO with its own pathogenesis, epidemiology, recent research studies, and general medications. Treatment and monitoring of the jaw are essential for the clear diagnosis and management of CNO/CRMO patients in the field of dentistry and maxillofacial surgery.

Purpose: We report a case of chronic recurrent multifocal osteomyelitis of the shoulder. Materials and Methods: A 16 year-old male who had suffered from chronic recurrent multifocal osteomyelitis of the shoulder was diagnosed by clinical features and biopsy and was treated with arthroscopic debridement and Naproxen. Results: Symptoms was subsided without relapse during 16 months follow up. Conclusion: Chronic recurrent multifocal osteomyelitis is rare disease and it can be misdiagnosis because of its rarity and non-specific clinical presentation. This is a report of a case of chronic recurrent multifocal osteomyelitis of the shoulder in 16 years man.

Myotonic dystrophy type 1 (DM1) is an autosomal dominant multisystem disorder caused by the expansion of cytosine-thymine-guanine (CTG) repeats in the myotonic dystrophy protein kinase (DMPK) gene. Some literatures indicated that DM1 had incidental CNS lesions such as white matter lesions and diffuse gray matter atrophy. We report a patient with DM1 whose brain magnetic resonance image (MRI) showed multifocal hyperintense lesions and cystic lesion on both frontotemporoparietal lobes.

A 21-year-old female patient complaining of hemiparesis was diagnosed with right middle cerebral artery infarction. No risk factor was found, despite an extensive young-age stroke work-up, except her history of marijuana use. The patient had smoked marijuana for treating depression for more than five years. Magnetic resonance angiography showed multifocal intra- and extracranial stenoses, suggesting cannabinoid-induced vasculopathy. Since the use of illicit drugs has increased nationwide, physicians should consider it as a possible cause of a stroke due to an unknown etiology.

Gross lesions of multifocal interstitial nephritis, often called 'white spotted kidney', can be caused by various bacterial or viral hematogenous infections [1, 2]. The purpose of this study was to determine whether there is an association between these lesions in slaughter pigs and the causative agents in Jeju. (omitted)

In a flocks of broiler, 29 days old, was submitted to Iksan-branch, Livestock Development and Research Institute of Chonbuk province. Grossly, their feathers were ruffled and multiful hemorrhage were presented in the thigh and pectoral muscles. There were multifocal foci on the liver surface and enlarged and edematous on bursa of Fabricius. The coagulative materials, which were blood-tinged, were filled in cecum, and Eimeria oocysts were detected in the cecal contents. Microscopically, macrogametes were noted in the cecum, degeneration and necrosis of lymphocytes in the medullary area of bursal follicles, and multifocal necrosis of hepatocytes. There were positive in the infectious bursal disease(IBD) through selologic test and Salmonella gallinarum were detected. This report is a mixed infection case of coccidium, IBD and fowl typhoid in a flocks of broiler.

Intravenous immunoglobulin (IVIg) is the treatment of choice for many autoimmune neuropathic disorders such as Guillain-Barre syndrome (GBS), chronic inflammatory Demyelinating neuropathy (CIDP), and multifocal motor neuropathy (MMN). IVIg is preferred because the adverse reactions are milder and fewer than the other immune-modulating methods such as steroid, other immunosuppressant such as azathioprine, and plasmapheresis. IVIg also has been used in other autoimmune neuromuscular disorders (inflammatory myopathy, myasthenia gravis, and Lambert-Eaton myasthenic syndrome) and has been known as safe and efficient agent in these disorders. Since IVIg would get more indications and be used more commonly, clinicians need to know the detailed mechanism of action, side effects, and practical points of IVIg.
