Helicobacter pylori(H. pylori) infection is considered the most important cause of chronic active gastritis and peptic ulcer. To determine the prevalence, distribution and it's relationship to degree of inflammation, gastric biopsy specimens were obtained from 331 nonulcer dyspepsia(NUD) patients consisting of 52 H. pylori negative normal volunteers and 279 H. pylori infected patients. Lymphoid follicles, degree of acute and chronic inflammation(Grade 0 to 3), and degree of H. pylori(Grade 0 to 4) were observed. The prevalence of H. pylori in NUD was 84.29%. The lymphoid follicles were found in 138 patients(41.7%) and only 5 patients(l.5%) without H. pylori showed lymphoid follicles. There was strong a relationship between lymphoid follicles and degree of acute and chronic inflammation and intensity of H. pylori infection(P<0.001). Acute and chronic inflammation were more serious in the antrum than body in H. pylori infected patients. There was no relationship between lymphoid follicles and the site in the stomach of H. pylori infection(P<0.078), but the body portion had an increased frequency of lymphoid follicles compared to the in antrum. Our results indicate that the prevalence of H. pylori infection in Korea is higher than in Western people and the degree of acute and chronic inflammation are strongly correlated with the presence of lymphoid follicles. The lymphoid follicles are believed to be absent from the normal stomach and their presence is strongly associated with H. pylori infection. The fact there is an that increased frequency of lymphoid follicles in H. pylori infected patients, and that they are more prevalent in the body of the antrum, support the concept that H. pylori may be a precursor in the development of primary gastric lymphoma.

Since the first experimental nerve graft by Philipeaux and Vulpian in 1870, many successful graft have been reported by Bunnell, Boyes, Millesi, Sunderland and Seddon. Advances in microsurgery techniques prompted Millesi to introduce the concepts of interfascicular nerve grafting whereby groups of fascicles, and not whole nerve, are connected together. Hunt and Taylor described a free vasculized nerve graft with microvascular anastomoses and obtained rapid axonal advance and maturation of grafted nerve in a clinical case. It is true that a nerve graft should be inferior to an end-to-end nerve repair, because in the case of nerve grafting the axon have to cross two suture lines instead of one. On the other hand, nerve grafting is indicated whenever a significant gap is produced in a nerve as a result of injury. In a retrospective study of 46 patients, defect of the nerve with treated by nerve graft were analyzed from March, 1983 to January, 1993 and following results were obtained. 1. Nerve graft was useful method to repair nerve whenever a significant gap is produced in a nerve as a result of injury. 2. The sural nerve was used as a donor nerve and vasculized nerve graft can be useful. 3. Postoperative results of cases caused by electric burns were worse than others. 4. There were little significant value in the treatment results between epineural and perineural nerve graft. 5. Recovery of intrinsic function in median and ulnar nerve lesion above the elbow was poor and recovery of the intrinsic function in median nerve graft at the forearm level was better than level for lesion in the ulnar nerve at the same level.

Paneth cell-rich carcinoma is essentially an adenocarcinoma with a predominance of Paneth cells. A 60-year-old male patient was admitted with a history of abdominal distension for several months. Endoscopic examination revealed a large ulceroinfiltrative tumor involving most of the areas of the stomach. The biopsy of the lesion confirmed poorly differentiated adenocarcinoma and total gastrectomy was followed. The submitted total stomach contained a diffuse infiltrative Borrmann type IV mass with ulceration, 8.0 3.5 cm, at the body along the lesser curvature. Microscopically, it was composed of Paneth cell differentiated cancer cells and poorly differentiated tubular adenocarcinoma cells. The Paneth cell differentiation was characterized by cytoplasmic coarse eosinophilic granules, which were PAS-positive and positive reaction for lysozyme. Electron microscopic examination showed numerous, spherical, electron-dense, homogeneous granules corresponding to those in Paneth cells as well as mucin granules in the signet-ring cells, and various intermediate forms in some cancer cells, which might be immature in the Paneth cell lineage.

We present a case of mucous gland adenoma arising from the main bronchus of the lower lobe of the left lung in terms of clinicopathologic, immunohistochemical, and ultrastructural aspects as well as review of related literatures. The patient, a 31-year-old female, was admitted to Catholic University Medical College Hospital with complaints of coughing and purulent sputum for about seven years. The chest CT showed a severely calcified tumor in the left lower lobe of the lung. Grossly, the calcified tumor arising from the main bronchus protruded into the lumen and showed bronchiectasis of the lower lobe and atelectasis of the upper lobe of the lung. The tumor was pale brown-gray and sharply circumscribed and showed some small cystic spaces filled with mucoid material. Microscopically, most of the tumor showed dystrophic calcification. The growth pattern of the tumor is composed of cysts, tubules, and glands lined by cytologically bland columnar, cuboidal, or flattened mucus secreting cells. Electron micrograph of tumor cells showed some round or oval mucous granules measuring 0.5-1.8 micrometer.

The dendriform pulmonary ossification (DPO) is a rare condition of unknown origin in which branching mature bony spicules, usually containing marrow, are found within the alveolar septa. DPO manifests slow progression over many years or may remain unchanged; spontaneous regression has not been recorded. Most patients have no symptoms directly attributed to the ossification, although they may have symptoms due to the underlying fibrotic process. We experienced a case of DPO in 38 year-old-man who presented with cough and sputum for a month. The chest X-ray showed marked coarsened interstitial lung markings in both lungs, especially in the lower lobes. Open lung biopsy was done. Grossly, there were significant dendriform osseous structures. Histologically, branching arrays of mature bone were found in the interstitium and occasionally in alveolar spaces. Some bony trabeculae contained fatty or cellular marrow. The alveolar septa showed fibrous thickening with chronic inflammation. The transition between fibrosis and bone tissue was observed. Our case suggests that dendriform pulmonary ossification may be a rare special manifestation of chronic fibrosing interstitial inflammation of the lung. Osseous structures seem to derive from metaplastic bone formation in the vicinity of undergoing fibrous process.

BACKGROUND: Management of massive rotator cuff tears can be challenging because of the less satisfactory results and a higher retear rate regardless of the use of open or arthroscopic repair technique. METHODS: We retrospectively analyzed 102 cases of massive rotator cuff tear treated with either open or arthroscopic repair. Open repair was performed in 38 patients; and arthroscopic repair, in 64 patients. The mean age at the time of surgery was 59.7 years in the open group and 57.6 years in the arthroscopic group. RESULTS: The Constant score increased from the preoperative mean of 55.9 to 73.2 at the last follow-up in the open repair group and from 53.8 to 67.6 in the arthroscopic repair group (p<0.001 and <0.001, respectively). The University of California at Los Angeles (UCLA) score increased from a preoperative mean of 17.7 to 30.8 at the last follow-up in the open group and from 17.5 to 28.7 in the arthroscopic group (p<0.001 and <0.001, respectively). No statistically significant difference in the Constant and UCLA scores was observed between the two groups at the last follow-up (p=0.128 and 0.087, respectively). Retear was found in 14 patients (36.8%) in the open group and 39 patients (60.9%) in the arthroscopic group (p=0.024). CONCLUSIONS: Open and arthroscopic repairs of massive rotator cuff tears may provide satisfactory clinical results with no significant difference. However, a significantly lower retear rate was observed for the open repair group compared with the arthroscopic repair group.

Myofibrosarcoma of the breast is a rare malignant mesenchymal tumor that has been reported in only four well documented cases so far. We report a case of myofibrosarcoma of the breast in an 88-year-old man who complained of a palpable mass for 1 year. Microscopically, the tumor consisted mainly of spindled cells, arranged in irregular fascicles and embedded in broad bands of dense hyalinized collagen. It showed ill-defined border infiltrating the adjacent adipose tissue, moderate cellular pleomorphism, and high mitotic rate (8~9/10 HPF). Immunohistochemical study confirmed myofibroblastic differentiation of the tumor cells with diffuse strong reaction for vimentin, smooth muscle actin, and fibronectin.

Three rare tumors of the oral cavity are presented. Lingual chondromas, approximately twenty to thirty cases appear to have been reported since the lesion was first described by Berry in 1892, which are usually seen on the lateral borders in the anterior two thirds of the tongue, while the ventral surface and the posterior third are rarely involved. Chondromas of the tonsil are of very rare occurrence, which are thought to arise as a result of metaplasia, rather than from embryonic rests, with chronic fibrosing inflammation being the inciting factor. Because of its rarity, the following cases of chondroma of the tongue and tonsil are being added to small list of such case reported in the literature.
