The mucoepidermoid carcinoma is a rare tumor in the lung. A case of bronchial mucoepidermoid carcinoma diagnosed by fine needle aspiration cytology is presented. The smear showed many intermediate cells with occasional mucus-secreting cells. Malignant squamous cells were not present. The cellular arrangement of intermediate cells was overlapping and grouped in ball-like fashion. These cytologic features are unique for diagnosis of this tumor.

PURPOSE: In this study we analyzed the results of visual field tests in patients diagnosed with a brain lesion in an ophthalmology clinic. METHODS: The medical records of 55 patients who underwent visual field examinations and diagnosed with brain pathology using magnetic resonance imaging (MRI) from January 1, 2005 to June 30, 2014 were retrospectively investigated. RESULTS: Of the 55 patients (M:F = 30:25), 31 displayed symmetrical hemianopsia, a typical visual field defect associated with brain lesions. Twenty-four patients showed atypical visual field defect (20 showed normal visual field despite the brain lesion, 3 had bilateral narrowing of the peripheral visual field in 2 cerebral infarctions and 1 multiple sclerosis, and 1 had horizontal inferior visual field defect in 1 eye from nasopharyngeal cancer). CONCLUSIONS: Patients having a brain lesion with the optic tract invasion may present with atypical visual field defects. The peripheral visual field constriction and horizontal inferior visual field defect in 1 eye could be the visual field defect in patients with a brain lesion.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat pain and inflammation. There are two kinds of NSAID classified according to the selectivity of COX-2 inhibition: non-selective NSAIDs and cyclooxygenase (COX)-2 inhibitors. Non-selective NSAIDs have a high incidence of gastrointestinal and bleeding-associated adverse events, while COX-2 inhibitors are safer in terms of these events. However, COX-2 inhibitors are thought to cause increased cardiovascular events. The COX-2 inhibitors rofecoxib and valdecoxib were withdrawn from the market over safety concerns. Three COX-2 inhibitors are now available in South Korea after the recent approval of etoricoxib and polmacoxib for osteoarthritis patients. After reviewing the history of and recent studies about the safety of COX-2 inhibitors, physicians should find new uses for old drugs.

Histologic changes suggesting HPV infection are occasionally found adjacent to squamous cell carcinoma or in squamous papilloma of the esophagus, but the relationship between HPV infection and benign and malignant squamous lesions of the esophagus is not yet dear. The aim of this study was to examine the role of HPV in squamous lesions of the esophagus. Microscopic examination with emphasis on HPV infection was done on 15 cases of squamous cell carcinoma and 26 cases of squamous papilloma. In situ hybridization technique for wide-spectrum HPV probe was performed on 35 endoscopically biopsied esophageal tissues. Among the histologic parameters suggesting HPV infection, acanthosis was the most frequent finding: 100.0% in benign and malignant esophageal lesions, and koilocytosis and intraepithelial capillary loops were the second (92.7%).: Dyskeratosis, basal cell hyperplasia and bi- or multinucleation were 52.3%, 44.0% and 34.1% in frequency, respectively. On in situ hybridization study, the HPV DNA expression rates of 10 squamous cell carcinomas with evidence of HPV infection and 15 carcinomas without evidence of HPV infection were 60.0% and 33.3%, respectively. In contrast to the carcinoma cases, only one (10.0%) of 10 squamous papillomas revealed positive signal. In conclusion, HPV infection is strongly associated with squamous cell carcinoma, but the causal relation of HPV to squamous papilloma is inconspicous.
