We present a case of a 13-year-old boy with Gorham's disease involving the thoracic and lumbar spine, femur, and gastrointestinal (GI) tract, which was complicated by recurrent chylothorax and GI bleeding. The presenting symptoms were intermittent abdominal pain, back pain, and melena. Esophagogastroduodenoscopy and colonoscopy showed no abnormal lesions, but duodenal biopsy showed marked dilation of the lymphatics in the mucosa and submucosa, which revealed positive staining with a D2-40 immunohistochemical marker. In cases of GI bleeding with osteolysis, the expression of a D2-40 marker in the lymphatic endothelium of the GI tract may help to diagnose GI involvement in Gorham's disease. To the best of our knowledge, this is the first case report to pathologically demonstrate intestinal lymphatic malformation as a cause of GI bleeding in Gorham's disease.

Objective: To study the expression of the mismatch repair proteins hMSH2 and nm23 in sporadic colorectal cancer, determine any inter-relationship, and further investigate any clinical significance. Methods: Expression of hMSH2 and nm23 proteins was assessed in 87 colorectal cancer tissues by SP immunohistochemistry, with analysis of survival using follow-up data. Results: In the sporadic colorectal cancer tissues, nm23 protein expression appeared independent of the histological type (P>0.05), but correlated with the invasion depth and lymphatic metastasis (P<0.05). In contrast, hMSH2 protein expression was not significantly correlated with these clinicopathologic features (P>0.05), although it positively correlated with that of nm23 protein in the sporadic colorectal cancers (rs=0.635, P<0.05). Combined expression of the two was found to be related with invasion depth, lymphatic metastasis and prognosis of sporadic colorectal cancer (P<0.05). Conclusion: nm23 protein level was related with the degree of malignancy, and could be used as an index to predict the invasion and metastasis potential. The expression of hMSH2 protein is positively correlated that of nm23 protein, and the combined expression of the two has certain guiding significance for the prognosis of sporadic colorectal cancer.

The Z-plasty has been known as a most common surgical treatment of congenital circumferential constriction band syndrome of the hand. There were thirteen patients of congenital circumferential constriction band syndrome of the hand. All patients underwent Z-plasty under microscope. we did microsurgical dissection to minimize vascular, neural and lymphatic injury, and then considering secondary correction and scar contracture, tried to preserve as much subcutaneous fat and skin flap as possible without any excision. There were less skin necrosis and lymphedema as a result of vascular compromise. Using microscope offers several advantages. First, preventing vascular, neural and lymphatic injury. Second, getting an accurate suture approximation. finally, preserving as much subcutaneous fat and skin flap as possible without any excision. The outcome of digit growth and contour can be excellent than we expected. As a results, we believe that correction of congenital circumferential constriction band syndrome of the hand under the microscope have better results.

Lymphangioma is a benign tumor resulted from abnormal communication between large dermal lymphatic channels and central lymphatic system. The tumor is encountered more often in the neck and axilla and less often in mediastinum, omentum, retroperitoneum, and scrotum. It rarely developes at urogenital system, and there has been no previous description of lymphangioma involving the bladder wall in Korea. We report a case of 35-year-old female with infected huge lymphagioma ansing from pelvic cavity and involving bladder wall.

Lymphangioleiomyomatosis (LAM) is a rare, cystic lung disease that is associated with mutation in the tuberous sclerosis genes, renal angiomyolipomas, lymphatic spread and a remarkable female gender predilection. The pathology of LAM is represented by the proliferation of immature smooth muscle cells in the walls of airways, and venules and lymphatic vessels in the lung. The clinical course of LAM is characterized by progressive dyspnea on exertion, recurrent pneumothorax and collections of chylous fluid. The diagnosis of pulmonary LAM can be made on chest X-ray, a high-resolution CT scan and lung biopsy. We experienced a case of pulmonary lymphangioleiomyomatosis in a 28-years-old female patient who had suffered from progressive dyspnea on exertion, so we report on it along with a brief review of the relevant literature.

From 2006 to 2009, 50 pigs suspected of enteritis associated with porcine circovirus type 2 (PCV-2) (EAPC) were collected. Gross and histopathologic examinations and immunohistochemistry (IHC) were performed on the small intestine of 50 pigs. The pigs with EAPC were concentrated in grower pigs (68%), and diarrhea (84%) was the most common clinical sign. Grossly, the walls of the small intestine were thickened, and mesenteric lymph nodes were enlarged. The histopathologic features in the small intestine with EAPC were characterized by lymphoid depletion, histiocytic infiltration, and formation of basophilic grape-like inclusion bodies and multinucleated giant cells in gut-associated lymphatic tissue (GALT) and lamina propria. According to IHC, PCV-2 antigens were more intense and distributed widely in GALT (98%) than lamina propria (82%) of the small intestine. Co-infection with other enteric pathogens was detected in 26 pigs (52%). Twenty-four pigs (48%) were confirmed to be a PCV-2 single infection. Collectively, infected PCV-2 in the small intestine may induce an immunosuppressive status of individuals and then allow secondary co-infections in the digestive system. This study shows that PCV-2 can induce diarrhea and enteric lesions in pigs without a co-infection of other enteric pathogens.

A 13-year old female miniature Poodle was presented with ventro-abdominal skin purpura. All mammary glands were included, but right side mammary glands and left thoracic gland were mild while left abdominal and inguinal glands were moderately changed. Overlying skin of mammary glands was purple colored, thickened, and firm. Yellowish brown colored mammary discharge was noticed from every teats except cranial thoracic gland. On histologic finding, dermal lymphatic vessels were filled with tumor emboli that stained positively with cytokeratin. This case was diagnosed as inflammatory mammary carcinoma by clinical examination and histopathologic finding.

Vascular malformations (VMs) in the head and neck region are present at birth and grow commensurately with the child, they can result in significant cosmetic problems for the patient, and some may lead to even serious life threatening hemorrhage. Although the molecular mechanisms underlying the formation of these VMs remain unclear, lesions are known to result from abnormal development and morphogenesis. Histologically, there are no evidence of cellular proliferation, but rather progressive dilatation of abnormal channels, which VMs are designated to their prominent channel types such as capillary, venous, lymphatic, arterial, and combined malformations. VMs with an arterial component are rheologically fast-flow, whereas capillary, lymphatic, and venous components are slow-flow. In this article, we review the clinical presentations, diagnosis, and management of VMs of facial regions with author's embolization and surgical treatment cases.

Catechins exhibit a hypocholesterolemic effect in cholesterol-fed animals. The present study was conducted to examine whether (+)-catechin influences the absorption of cholesterol in rats. Male Sprague-Dawley rats were fed ad libitum an AIN-93G diet containing soybean oil for 5 wk. Rats with lymph cannulae were infused at 3.0 mL/h for 8 h via a duodenal catheter with a lipid emulsion containing radiolabeled cholesterol with or without (+)-catechin. Lymph was collected hourly for 8 h. The enteral infusion of (+)-catechin significantly lowered the lymphatic absorption of $^{14}$ C-cholesterol (21.1 $\pm$ 3.6% dose/B h) compared with controls infused with the lipid emulsion devoid of (+)-catechin (38.2 $\pm$ 1.2% dose/8 h). The intestinal absorption of $\alpha$-tocopherol (24.2$\pm$3.0% dose/8 h) also was significantly decreased by (+)-catechin infusion, relative to controls (32.2$\pm$2.2% dose/8 h). However, the lymphatic outputs of oleic acid and phospholipid were not affected by enteral (+)-catechin infusion. The results indicate that (+)-catechin has a profound inhibitory effect on the intestinal absorption of cholesterol and $\alpha$-tocopherol without affecting the absorption of fat.

Lymphangioma is a congenital malformation of the lymphatic system and is thought to result from the failure of the lymphatic system to connect with the venous system. Lymphangioma of the chest wall is a very rare disease entity, and only a few cases have ever been documented in the literature. To the best of our knowledge, there have been few cases of recurrent cavernous lymphangioma after surgical excision of a cystic hygroma on the same side of the chest wall. Here, we report a case of a cavernous lymphangioma of the chest wall in a patient who had undergone surgical excision of a cystic hygroma 19 years earlier.
