RESUMEN
Osseous choristoma represents the dense, mature, bony tissue in an abnormal location. We reported three cases of lingual osseous choristoma, herein, a year after the report of eight cases in 1998. All three lesions were at or close to the foramen caecum. The lesions were smooth, round or lobulated and pedunculated in shape and stony hard in consistency. All of them were preoperatively diagnosed, based on the above unique clinical findings without any radiography. The lesions were simply excised without local recurrence.

We compared a noninvasive serological test using a commercial immunoblot assay (Helicoblot 2.0) to tissue-based methods [rapid urease test (CLO test), histology and culture] in eighty Thai patients undergoing upper endoscopy. A true positive test was defined as at least two of the biopsy-related tests being positive. The CLO test was the most accurate test with sensitivity and specificity as high as 100%, whereas histology and culture had sensitivity of 100% and 72.2%, respectively, and the specificity of 72.7% and 96%, respectively. The serological test had a high sensitivity (97.2%) but exhibited an unsatisfactory specificity (40.9%). We concluded that the rapid urease test using multiple gastric biopsies was the most appropriate method for diagnosing H. pylori status. The role of immunoblot assay as a serological screening test in our population remains doubtful, but it may identify patients who have been infected with certain strains of H. pylori.

Radial scar, a descriptive term for a pathologic lesion, is composed of central area of fibroelastosis and distorted ducts, and peripheral zone of intraductal hyperplasia. This lesion often presents as a spiculated lesion, sometimes with microcalcifications, on mammography which may mimic malignancy such as tubular carcinoma. We report a case of radial scar with clustered microcalcifications incidentally found in the screened mammogram.
