Oncocytic mucoepidermoid carcinoma of the salivary glands.

Two parotid mucoepidermoid carcinomas with predominant oncocytic features were initially assessed on frozen section. Because of extensive oncocytic change, it was inferred that the lesions were most likely benign. Permanent sections revealed low-grade mucoepidermoid carcinoma with prominent oncocytic change (in more than 75% of the neoplasms) in both cases.

Interobserver variation in the histopathological assessment of Helicobacter pylori gastritis.

The histopathologic detection of Helicobacter pylori in gastric biopsy specimens is considered the gold standard for the diagnosis of H pylori infection. However, few studies have addressed the pathologists' reliability to detect the organism and to assess the degree of the related inflammatory changes. The objectives of this study were to determine the degree of agreement among the findings of four gastrointestinal pathologists in the semiquantitative evaluation of H pylori infection and gastritis.
