The present lesion was the first reported case of a benign intracystic phyllodes tumor in the inguinal region. We report the case of a 51-year-old female patient who presented with an inguinal mass. A clinical diagnosis of malignant lymphoma was considered in this case. The resected tumor was well-circumscribed and showed numerous papillary nodular protrusions into a central cystic cavity (3.5×2.5 cm). The microscopic findings showed hyperplastic epithelium-lined cysts with leaf-like intraluminal epithelium-lined bland stromal projections. The epithelial cell linings were strongly positive for estrogen and progesterone receptors.

Abstract PDF: Ectopic liver in the umbilicus is very rare, and a few cases have been reported in the world. It is thought that an increased intraabdominal pressure resulting in entrapment of liver cell nests causes the presence of liver in the umbilicus. It relates to neonatal problem such as infection. We report a case of ectopic umbilical liver in a stillborn male of 28 gestational weeks. His mother discovered loss of fetal movement 2 days before admission, and intrauterine fetal death was diagnosed by ultrasonography. Grossly, the umbilical cord was markedly swollen. On cut section, a well circumscribed, oval round, tan-colored soft mass was noted within the cord. Histologically, it consisted of hepatic cords without bile ducts. The umbilical vessels were distorted by the ectopic liver, and contained thrombi. These findings suggest that ectopic umbilical liver results in the intrauterine fetal death

Abstract PDF: Ectopic paragonimiasis has been diagnosed in many organs such as the mesentery, ovary, pleura, central nervous system, subcutis and very rarely in the liver. However, simultaneous involvement of the colon and liver, which mimics colonic cancer with liver metastasis, is quite unusual, and to our knowledge has never been reported. Our case is a 63 year old woman who visited our hospital because of upper abdominal pain. Radiologically, space occupying lesions were detected in the transverse colon, mesocolon and left hepatic lobe. After the radical presection, they were proved to be an ectopic paragonimiasis forming multiple cavitary parasitic granulomas with Charcot-Leyden crystals and degenerating eggs.

Abstract: Although heterotopia of pancreatic tissue is a developmental anomaly found in approximately 2% of all autopsies, pancreatic tissue within the thorax and mediastinum is uncommon. In most of these instances, the pancreatic tissue is a component of gastroenteric duplication cysts, intralobar pulmonary sequestrations or teratomas. We describe an anterior mediastinal cyst consisting entirely of pancreatic tissue. A previously healthy 27-year-old woman was admitted due to chest pain during deep inspiration. The computed tomographic scan of the thorax showed a large cyst occupying the right anterior mediastinum. The excised multilocular cystic lesion measured 12 cm in maximum diameter and contained a brown, turbid fluid. The wall was fibrotic and showed a haphazard mixture of ducts and exocrine acini without islets. The histogenesis of this lesion is unclear.

Abstract PDF: Most ectopic pregnancies occur in the fallopian tubes. There have been numerous theories to explain the occurrence of ectopic pregnancy in fallopian tubes. The most commonly held view is that the passage of the fertilized ovum through the fallopian tube is delayed or hindered by chronic inflammation and its sequelae. We designed a study to evaluate the details of histopathologic changes and the location of implantation and how they relate to the clinical history. 182 fallopian tube specimens from patients who had undergone total or partial salpingectomy were examined. A high incidence of non-specific inflammation of plicae and wall of tube (31.9%) and salpingitis isthmica nodosa (12.6%) were observed. Other associated findings included acute salpingitis, complex plicae or complex hyperplasia of tubal epithelium, fibrous adhesion with ovary, endometriosis, and calcification. History of previous ectopic tubal pregnancy was found in 8 cases. The cases with serum beta-HCG value above 2,500 I.U./L (group I, n=97) were more frequently noted in those exhibiting myosalpingeal invasion of trophoblast (67 cases) than in those without invasion (30 cases). Of the 182 tubal pregnancies, 117 (64.3%) cases were found in the ampulla and 47 (25.8%) cases in isthmic location. In 117 ampullary pregnancies, the products of conception were found intraluminally in 71 cases (60.7%), and extraluminally in 34 (29.1%) cases, of which the products of conception were found entirely extraluminal. The products of conception, found both within and outside the tubal lumen, were found in 12 cases (10.2%). Of 47 tubes with isthmic pregnancies, 33 cases were intraluminal (70.2%), 12 cases were extraluminal (25.5%), and two cases were mixed (4.3%). In conclusion, significant histopathologic abnormalities accompany a majority of ectopic tubal pregnancy, and myosalpingeal invasion of trophoblast is correlated with high serum beta-HCG. Thus, it is necessary to confirm not only the ectopic placental tissue but also the accompanying details of the other histopathologic findings or the pathologic evaluation of ectopic tubal pregnancy.

Abstract PDF: Renal dysplasia results from aberrant metanephric histogenesis caused fundamentally by a defect in inducer tissue or responding tissue. Dysplastic kidneys vary tremendously in gross and microscopic appearance but are characterized by abnormal organization and a mixed population of primitive structures, such as fetal or immature cartilage, dysplastic ducts, immature tubules, and undifferentiated mesenchyme. We report a case of unilateral multicystic renal dysplasia associated with an ipsilateral ectopic ureteral orifice entering a seminal vesicle cyst in a 33-year-old man. He was admitted due to primary infertility which had developed three years ago. The his semen analysis revealed oligospermia. No evidence of a family history of renal dysplasia was reported. Microscopic examination showed that the entire kidney was composed of cysts lined by flattened cells, dysplastic ducts and immature tubules surrounded by collars of spindle cells, primitive mesenchyme, and a few aberrantly formed glomeruli.

Abstract PDF: Ectopic liver is a rare entity that has been previously identified during abdominal exploration for other surgery and this has usually been described in the vicinity of the liver such as on the gallbladder, hepatic ligaments, diaphragm, thoracic cavity, adrenal glands, pancreas, omentum, spleen, esophagus and umbilical cord. Most cases of ectopic liver reported in the literature were located in the gallbladder. We report here on a case of ectopic liver related to the gallbladder, and this was encountered during an elective laparoscopic cholecystectomy.

Abstract PDF: There are few reports of the endoscopic and histological features of ectopic sebaceous glands in the esophagus. Recently we observed a 2 mm whitish flat elevated nodule in the lower esophagus. A biopsy was taken under the clinical impression of a papilloma or ulcer scar. Histology revealed normal esophageal mucosa with mature ectopic sebaceous glands located in the lamina propria with no visible hair follicles. We report this case with a brief review of the literature related to the histological findings and histogenesis of esophageal ectopic sebaceous glands.

Abstract PDF: We reviewed histological and immunohistochemical findings of the endometrium in 28 cases of ectopic pregnancy and 11 cases of intrauterine pregnancy without chorionic villi or syncytiotrophoblast. 1) Twenty cases(71.41/o) of ectopic pregnancy revealed gestational patterns and 8 cases(28.6%) showed non-gestational patterns, which were menstrual phase in 3 cases, proliferative phase in I case, early secretary phase in 3 cases and mid secretary phase in 3 cases, respectively. Implantation sites were present in 36.40/o of intrauterine pregnancy. 2) Endometrial spiral arterioles tend to be more prominent with frequent intimal proliferation and thickening of the wall in intrauterine pregnancy than in ectopic pregnancy although it was not statistically significant(p=0.271). 3) Deposition of fibrinoid material in the endometrium was present in 72.7% of intrauterine pregnancy and 25% of ectopic pregnancy. Thrombosis was present in 72.7% of intrauterine pregnancy and 5% of ectopic pregnancy. Hyalinized vessels were also present in 90.9% of intrauterine pregnancy and 200/o of ectopic pregnancy. These were statistically significant(p=0.0002, 0.0209 and 0.0004), but not diagnostic. 4) On immunohistochemical study for intrauterine pregnancy, the rates of positive reaction to human placental lactogen, cytokeratin and human chorionic gonadotropin were 45.5%, 45.5% and 9%, respectively. We concluded that HFIL and cytokeratin are reliable and sensitive markers for implantation site.

Abstract PDF: Paragonimus westermani can cause extrapulmonary parasitism in various sites such as abdominal organ, brain, eye, periorbital tissue, heart and pericardium, mediastinum, and subcutaneous tissue. We experienced a case of subcutaneous paragonimiasis involving the breast. The lesion exhibited chronic granuloma with scattered eggs of paragonimus westermani. The adult worm was not found within the lesion which should be disintegrated a year ago by praziquantel treatment. This relatively rare involvement of ectopic paragonimiasis should be differentiated from breast malignancy.

Abstract PDF: A case of unilateral multicystic renal dysplasia was reported in view of rarity, and a review of literature 23-year-old female was admitted to Kyung Hee University Hospital with a complaint of urinary incontinence. An excretory urogram revealed non-visualization of the right kidney. The right ureter had opening at the 2 cm above the vaginal introitus. The resected right kidney revelaed multilobulated outer surface with multiloculated cystic struture on cut surface. The associated anomaly was uterine didelphy. The condition was treated by nephroureterectomy.
