An unusual pattern of focal involvement of lymph nodes by Hodgkin's disease is described using the name Interfollicular Hodgkin's Disease. It is characterized by florid reactive follicular hyperplasia which overshadows involvement of the interfollicular zones by Hodgkin's desease. The importance of interfollicular Hodgkin's disease rests on its misdiagnosis as a benign lesion. We report a case of interfollicular Hodgkin's disease in a 34-year-old female patient in the inguinal area. The lymph nodes showed reactive follicular hyperplasia. The focal interfollicular spaces were invaded by Hodgkin's disease. The Reed-Stemberg cells stained positively with CD15 and CD30 antibody in the immunohistochemical stain. An in situ hybridization study looking for EBV was negative in these R-S cells.

Simple bone cyst (SBC) is very rare in adult ribs. The diagnosis basically relies on conventional radiography and occasionally on CT. There has been no earlier publication on PET/CT diagnosis of SBC. We report a case of adult costal SBC diagnosed by positive 18F-fluorodeoxyglucose (FDG) uptake. Histology showed the FDG uptake to be associated with reactive woven bone formation and nonspecific chronic inflammation. Correlation of PET, CT, plain radiography and sonography are also described.

Lymphoma is the third most common childhood malignancy after leukemia and brain tumor. In contrast to adult non-Hodgkin's lymphoma, that occurring in children is usually found extranodally. The most common site is the abdomen, including the gastrointestinal tract, kidney and pancreas, and the next most common is the extranodal head and neck. Gastrointestinal non-Hodgkin's lymphoma in adults is usually considered to be MALT lymphoma, a distinct B-cell type, but the occurrence of this variety in the small bowel of children is relatively rare. We report a case of high-grade MALT lymphoma occurring in a nine-year-old boy who presented with ileoileal intussusception.

The leiomyoma of the vagina is relatively rare benign tumor, but most common mesencymal tumors in adult woman. There does not seem to be a correlation between the existence of vaginal leiomyoma and uterine or other leiomyomas. But, recently we experienced a case of vaginal leiomyoma arising in the lateral vaginal wall and concomitant uterine leiomyoma. Now we present it with a brief review of the case and its literatures.

Ovarian myoma is a rare mesenchymal tumor, accounting for only 1% of benign ovarian neoplasm. These tumors only originate from smooth muscle on the walls of blood vessels in the cortical stroma, in the corpus luteum and in the ovarian ligaments at the point of attachment to the ovary. Most patients are asymptomatic and the tumors are usually found incidently during operations or at autopsies. Two cases of ovarian myoma experienced in our hospital recently are reported with a brief review of the literatures."

Congenital self-healing reticulohistiocytosis (CSHR) is a rare variant of cutaneous reticulohistiocytosis. We report a newborn who had about 25 reddish brown papulonodular lesions on whole body at birth. No extracutaneous involvement was found. All skin lesions involuted within 4 months spontaneously. Biopsy of a skin lesion showed marked aggregated histiocytic infiltration with some eosinophils. S-100 protein and lysozyme were positive. Electron microscopy revealed numerous dense bodies, often with a myelin-like core and some Birbeck granules. We described a detailed clinical features of this case and reviewed the literatures.

Adenoma malignum is a well differentiated form of adenocarcinoma. Despite of benign histologic appearance, this tumor has malignant clinical course. Because of its rarity and subtle histologic changes, it may be missed. Therefore it has poor prognosis. Early diagnosis and early treatment is required by thorough examination. We report one case of adenoma malignum of uterine cervix with a brief review of the literature.

To our knowledge, only one case of vaginal cavernous hemangioma in pregnancy has been reported all over the world and there is no report in Korea. The authors have experienced one case of vaginal cavernous hemangioma in pregnancy and report our case with a brief review of literature.

Meconium peritonitis results from in-utero perforation of gastrointestinal tract, with subsequent leakage of meconium into the peritoneal cavity. Patent processus vaginalis of male or female fetus may lead to migration of meconium into inguinal canal, and these infants may present meconium filled hydroceles at birth. The predominance of meconium hydrocele in the male infant may be due to the obliteration of processus vaginalis occuring later than in the female fetus. We report a rare case of bilateral meconium hydrocele in the female newborn, which mimic clinical symptoms and ultrasonographic findings of incarcerated hernia.

To our knowledge, implantation into the uterine muscle wall is one of the rare form of ectopic pregnancy, with only 16 cases reported until 1995. The early diagnosis depends upon the sonographic finding of intramural gestational sac-like growth and persistent high beta human chorionic gonadotropin (beta-hCG) levels after dilatation and curettage. But, nobody can't exclude intramural pregnancy in case that associated with adenomyosis in uterus in spite of negative beta-hCG. Hsieh et al. and Dousias et al. mentioned 2 cases of such situation with negative beta-hCG result. And confirmative diagnosis depends upon the pathologic finding for specimen obtained from laparoscopic or explorative hysterotomy. The authors have experienced one case of intramural pregnancy in uterus and report our case with a brief review of literature.
