Littoral cell angioma (LCA) of spleen is an uncommon vascular neoplasm of littoral cell origin. It is well established that LCA may be associated with other malignancy or autoimmune disorders. We describe a 34-year-old woman with viral hepatitis C associated liver cirrhosis who presented with the incidental finding of LCA. She showed ascites, esophageal varix and drowsy mentality. Abdominal computed tomography (CT) showed multiple benign looking nodules in both hepatic lobes, but no abnormality in spleen. Liver transplantation and splenectomy were performed. Microscopic findings revealed narrow anastomosing vascular channels lined with plump cells that exfoliated into the lumen. Immunohistochemically the lining cells were positive for CD31, CD68 and negative for CD34, consistent with LCA. Herein, a second case of an incidentally detected LCA with cirrhosis, viral hepatitis C associated in Korea is reported.

Fibrous dysplasia is a common benign disorder of bone in which normal bone marrow is replaced with fibro-osseous tissue. As PET/CT is increasingly used for the staging of different malignant disease, incidentally found fibrous dysplasia with increased FDG uptake may mimic metastasis. We report on a 46-year-old woman with fibrous dysplasia who underwent PET/CT because of suspected recurrence of breast cancer and was misdiagnosed as a bony metastasis with a focal FDG uptake on left proximal femur. This lesion was interpreted as fibrous dysplasia based on MRI in addition to the plain radiographs. We conclude that MRI in addition to radiography may help to differentiate fibrous dysplasia mimicking metastasis on PET/CT in the patients with malignancy.

Vitiligo has been associated with various disorders including thyroid disease, type I diabetes, alopecia areatal and pernicious anemia. It has been purported to be caused by autoimmune response. Vitiligo and alopecia areata occurring in the same patient has often been found, but colocalization of these two diseases has been rarely reported. It is suggested that this concurrence can result from a nonspecific immune mechanism affecting not only the melanocyte but the epithelium of the hair follicle as well. Thus colocalization can occur due to costimulation of a helper T-cell-mediated immunologic response or through inactivation of a suppressor-mediated response and other composite mechanisms such as neurogenic factors, stress and infection. We report a 17-year-old Korean female who presented with a 1-year history of alopecia and depigmentation on the same site of the left eyebrow. We diagnosed this skin lesion as colocalization of vitiligo and alopecia areata by both clinical and histopathological findings.

Desmoid tumor is rare neoplasm originated from fibrous sheath or musculoaponeurotic structure. It is classified as benign tumor histologically, but clinically, it has malignant characteristics due to its infiltrative growth to adjacent organ and frequent local recurrence. Especially, mesenteric desmoid tumor shows poor prognosis because of its symptoms of pain, intestinal obstruction, ureter obstruction and fistula formation and high frequency of recurrence. We experienced a case of mesenteric desmoid tumor in a 64-year-old woman with a painless abdominal mass. Laparoscopic exploration was performed and 10 cm sized mesenteric mass was identified, which resected widely and the diagnosis was confirmed with desmoid tumor by pathologic report. We reviewed the feature of the mesenteric desmoid tumor, that is, pathophysiology, clinical presentations, diagnosis, treatment and prognosis.

A 63-year-old woman was referred to a breast surgeon with a breast mass discovered incidentally during follow-up study after colon cancer surgery. Invasive adenocarcinoma was revealed on core needle biopsy. Wide excision of the breast including the tumor was performed. On standard histological examination the tumor showed features of moderately differentiated adenocarcinoma. The immunohistochemistry study revealed positive results for cytokeratin (CK)20 and CDX2, but negative for CK7. These are typical characteristics for colon cancer. Considering her history of subtotal colectomy for sigmoid colon cancer, it is presumable that the mass in the breast was of colonic origin, and it was an extremely rare case of metastasis to the breast from primary colorectal neoplasm. Although the instance is rare, clinicians should keep the possibility of breast metastasis from colorectal cancer in mind for early and correct diagnosis.

Acute hemorrhagic edema of infancy is an unusual form of leukocytoclastic vasculitis occuring in children from the age 4 months to 2 years. The etiology remains unknown. Numerous studies, however, suggest acute hemorrhagic edema of infancy as an immune-mediated vasculitis in response to a variety of antigenic stimuli. We report a case of an acute hemorrhagic edema of infancy; 11-month-old boy with a history of fever for 3 days and a history of purpuric rash on the extremities, trunk, buttock and oral mucosa for 2 days.

Crohn's disease was originally described as a small bowel disorder and has been known to involve the large bowel in approximately 40% of all cases with or without concomitant ileal component. We describe two cases of Crohn's diseas of small intestine and colon with a summary of differential diagnosis with ulcerative colitis. Both cases were originally diagnosed and treated as ileal tuberculosis. Grossly, there were skip lesions in both cases with prominent pseudopolyps and ulcerations in colon. Also noted were typical serpentine lesions in ileum as well as in colon. Microscopically, transmural inflammation was confirmed and one case showed scattered noncaseating granulomas in the wall. Submucosal edema and fibrosis with thickening of the wall was not prominent in colon. Polymerase chain reaction performed on paraffin block for the demonstration of Mycobacterium tuberculosis in one case showed negative reaction.

OBJECTIVES: This study was conducted to be identify the effects oral hygiene improvement of the elderly by caregiver in a rural. METHODS: It recruited Fifty three elderly patients were recruited who admitted at a long-term hospital located in Mokchon city, Chungchungnam-do province. as the intervention group. Fifty two elderly patients group were selected another one long-term care hospital in Daegu city as control group. study was conducted for seven months. long-term care hospital. for seven months from Dec. 2007 to June 2008. For three months, the caregivers provide tooth brushing and cleaning artificial teeth once a day, to intervention group. once a day for three months. RESULTS: Before the program there was no significant difference between the control and the intervention groups in general characteristics, prevalence rates of diseases, oral sanitary condition. Dental plague score was decreased significantly (p<0.001) before and after intervention in the intervention group. Using analysis of covariance for evaluation of the effect of the intervention, a significant difference was observed between the intervention group and the control group (p<0.01). CONCLUSIONS: These results were thought to be used as important basic data to develop oral health management program for elderly patients who needed long-term care.

Background: Oxidative stress is generally accepted as one of the principal pathogenesis of vitiligo, and keratinocyte-melanocyte interactions are also thought to play critical roles. It is well-known that antioxidant response and autophagy protect cells against oxidative damage, but the details and the compensatory relationship between the two mechanisms in the keratinocytes of vitiligo lesions remain unclear. Objective: To evaluate the antioxidant response and autophagy status of patients with vitiligo and to explore the interactions between these two mechanisms. Methods: Ten patients with clinicopathologically proven vitiligo and 10 normal controls were enrolled in our Department of Dermatology, Soonchunhyang University Hospital, Bucheon, Korea. Tissue samples of vitiligo lesions in the patient group and normal skin in the control group were immunohistochemically stained for nuclear factor erythroid 2-related factor 2 (Nrf2), Beclin-1, microtubule-associated protein light chain 3 (LC3)-II, and p62. The immunopositivity of epidermal keratinocytes was evaluated. Results: Keratinocytes in vitiligo lesions had a significantly lower expression of Nrf2 (p=0.002) than that in the cells of normal controls. The levels of autophagy markers did not differ significantly between the two groups, but decreases in the Beclin-1 and LC3-II levels, and an increase in the p62 level in the patient group may indicate a small decrease in autophagy of patients with vitiligo. Conclusion Decreased antioxidant response and reduced autophagy may trigger melanocyte apoptosis in vitiligo lesions.
