Leiomyomas are benign tumors of smooth muscle origin and are very rare in the female genital tract. To date, approximately 35 cases of urethral leiomyoma have been reported in the literature. A 34-year-old woman presented with a 3-year history of a mass at the urethral meatus. Physical examination showed 2 x 1.5 cm lump at the urethral meatus, posterior lip. Histologically the tumor was mainly composed of benign cigar shaped smooth muscle izells which were arranged in interlacing fascicles without cellular atypia or mitosis. Immunohistochemistry confirmed leiomyoma with positive staining for vimentin, desmin and muscle specific actin.

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.

Giardiasis is one of the most common causes of infectious diarrhea and it has a worldwide distribution. Although it is a relatively common disorder, histologically confirmed Giardiasis is a rare occurrence and there have been no previous reports in Korea. A 34-year-old man presented with a 2-year history of epigastric discomfort and left flank pain. On stool examination, many cystic forms of Giardia lamblia were noted. In biopsy specimens of the small intestine, there was moderate chronic inflammatory cell infiltration and several trophozoites of Giardia were observed in the intervillous space and luminal surface. The trophozoites were pear shaped symmetrical organisms with two nuclei, and measured 9~10 micrometer in length.

Teratocarcinoma is a form of mixed germ cell tumor composed of a mixture of teratoma and embryonal carcinoma. It is rarely found in the brain, but when present it is most commonly found in the pineal region. We investigated a case of primary teratocarcinoma in the pineal region. The patient was a 10 year old boy who had suffered from a bitemporal headache for one month. Brain CT and MRI revealed a rather well defined ovoid heterogenous mass in the pineal gland region, measuring 4.3 x 3.8 x 3.0 cm in size. Microscopically the tumor contained areas of immature teratoma and embryonal carcinoma. Immunohistochemical staining revealed positive reactions for cytokeratin, epithelial membrane antigen, carcinoembryonic antigen, and alpha-fetoprotein in the embryonal carcinoma component.

The dysplastic nevus is a rare form of melanocytic nevus in Korean people. During the past 5 years the authors experienced 5 cases in the St. Mary's Hospital and Kang Nam St. Mary's Hospital. The criteria and the histologic findings of dysplastic nevi are debated in the western literature. Clinically, all cases were greater than 5 mm in size with ill defined irregular borders and irregularly distributed pigmentation. Histopathologically, all cases showed numerous discrete individual nests of melanocytes located in the dermoepidermal junction and the papillary dermis and were characterized by extension of dermoepidermal component of the nevus at the "shoulder" beyond the dermal component of the nevus. There was no cytologic atypia of nevus cells in all cases. Our cases lacked personal or family history of malignant melanoma. Therefore, we believe our cases are nonfamilial, sporadic and benign nevi with no prognostic significance. A brief review of the literature and a discussion on the term "dysplastic" and clinicopathologic correlation are made.

Wilm's tumor, which is the most mommon renal tumor in childhood, has rarely been reported in adult. Diagnosis of Wilm's tumor in an adult is more apt to be accidental and is almost never suspected in the adult until discovered at operation or necropsy. Recently, we experienced a caseof Wilm's tumor in 20-year-old female patient with chief complaints of right flank pain and he maturia for two months. Renal angiogram revealed a huge renal mass replacing the upper portion of the right kidney. Nephrectomy was done under the impression of renal tumor. Grossly, the tumor was rather soft and relatively well circumscribed, measuring 13 x 8.3 cm in dimension with adhesion to renal capsule and perirenal adipose tissue. The cut surfaces revealed grayish brown in color with areas of multifocal necrosis and hemorrhage. Histologically, the tumor was composed of mainly ovoid or polygonal shaped undifferentiated blastemal cells with large areas of necrosis.

Graft-versus-host disease (GVHD) is a life threatening complication that may occur following allogenic bone marrow transplantation (BMT) in the patients with aplastic anemia, leukemia or genetic immunodeficiency. It has been known that GVHD occurs approximately 70% of recipients of BMT in western countries but no definite incidence has been reported in Korea. In our St. Mary's Hospital, GVHD occurs in about 30% of BMT recipients. Histopathologically the acute phase skin shows diffuse lymphocytic infiltrates in the upper dermis with extensive exocytosis. Scattered throughout the epidermis are many degenerated keratinocytes, which are often associated with one or more satellite lymphocytes (satellite cell necrosis). In the chronic phase, acanthosis, eosinophilic keratinocytes resembling colloid bodies and mononuclear cell infiltrates in the upper dermis are noted. We reviewed 5 cases of acute GVHD and 6 cases of chronic GVHD. All patients received allogenic BMT from Jan. 1, 1992 to July 1, 1993. Ten patients were male and one was female. The mean age was 34 (20-70). The pathologic diagnosis was 3 cases of CML, 2 of ALL, 2 of AML (FAB M2), 2 of aplastic anemia, 1 of CLL and 1 of AML (FAB M5). The interval from BMT to GVHD varied from 14 days to 4 years (median 220 days). The skin and GI tract were involved in all eleven cases. Ten cases were histologically proven by skin biopsies, and two cases by salivary gland and colonic biopsies, respectively. The histological findings of the skin, salivary gland and colonic biopsieds were described. Immunohistochemical stain of the skin was done using CD4, CD8, HLA DR and Leu 7 antibodies.

This report presents an unusual case of primary malignant melanoma in the midesophagus. The patient was a 36-year-old woman presenting with dysphagia and odynophagia. The resected esophagus and proximal stomach showed a dark purple large polypoid mass, measuring 6.0 3.3 2.0 cm, with a diffuse tan pigmentation of surrounding mucosa in the mid-esophagus and two small daughter nodules, up to 1.2 0.3 cm, in the lower esophagus near the gastro-esophageal junction. A microscopic examination revealed a malignant melanoma of epithelioid cell type confined to mucosa and submucosa with a diffuse melanosis. Cytoplasmic immunoreactivity for HMB 45 and S-100 protein were noted. An electron microscopic examination revealed large, loosely cohesive variable shaped cells with a few cytoplasmic premelanosomes.

Adrenal pseudocysts are rare benign cystic lesions resulting from a hemorrhage into a normal parenchyme of the adrenal gland. Although the frequency of adrenal cysts are increasing due to improved radiologic imaging techniques, only two cases have been reported in Korean literatures. A 63-year-old man was presented with a 10-year history of a mass in the right abdomen. Abdominal computed tomogram and a magnetic resonance image study showed a 9 cm sized well defined heterogeneous low attenuated mass in the right suprarenal area. Gross examination revealed an ovoid rubbery mass measuring 10 9 8 cm and weighing 355 gm. The content of this lesion was tan to deep brown, necrotic, and creamy with myxoid areas. Histologic examination revealed compressed, thin layers of adrenal cortex embedded in the fibrous tissue, and the cystic contents were eosinophilic fibrinoid materials with a few dilated cavernous vascular spaces lined by endothelial cells.
