Trichoepithelioma, a tumor of the hair follicle, is usually seen as multiple lesions, but occasionally appears as a single tumor. Multiple trichoepithelioma is a dominant hereditary skin conditions whereas solitary trichoepithelioma is not hereditary and is growing tumor, usually seen in adults. A case of 56 year old housewife with solitary trichoepithelioma was reported. The skin lesion appeased as a firm, skin colored papule and the size was 0.5cm in diameter on right side of nose. Shaving biopsy was done and showed a high degree of differentiation toward hair structure and horn cyst that the keratinization is abrupt and complete. The methood of treatment is a surgical excision and electrodesiccation but remain a scar due to surgical trauma. And so, we used a 5-fluorouracil ointment instead of surgical excision and electrodesiccation, The skin lesion on nose was cured completely as a result of 5-FU ointment application without any scar formation cosmetically.

Considering the recent advancements in endovascular management of aortoiliac aneurysms, the use of an iliac branch device (IBD) to preserve pelvic blood flow and reduce complications caused by embolization of the internal iliac artery (IIA) is recommended by various guidelines. Although the outcomes reported following IBD placement are mainly positive and durable, IBD-specific complications such as a type Ic endoleak and associated reintervention may occur. Moreover, only one IBD device and one type of balloon-expandable bridging stent graft for IIA are currently available on the domestic market. Here we present two cases of type Ic endoleak following IBD placement. In both cases, IIA diameter was slightly larger than the basic instructions for use. Notably, the initial procedures were considered successful; however, type Ic endoleaks were detected on 1-month follow-up imaging. This finding emphasizes the need for a precise preoperative evaluation, intraoperative manipulation, and postoperative follow-up.

Chronic eosinophilic pneumonia is a very rare disorder of unknown etiology characterized by striking systemic and pulmonary manifestations such as fever, weight loss, dyspnea, blood eosinophilia, and fluffy peripheral opacities on chest radiograph. A number of these patients developed asthma before or with the onset of illness. The roentgenographic lesion rapidly resoluted with corticosteroid and recurrence was occasionally occured in the same location. Histopathologic features of chronic eosinophilic pneumonia include dense aggregates of eosinophils, histiocytes, and multinucleated giant cells within alveolar spaces, interstitium, and bronchioles associated with scattered lymphocytes and plasma cells. We report a case of chronic eosinophilic pneumonia diagnosed by clinical, radiographic, and histologic findings with review of the literature.

Gold therapy of rheumatoid arthritis is effective, but adverse reactions are also common. There are some cutaneous, hematologic, renal, and pulmonary side effects which have been associated with immunologic abnormalities. Also, hypersensitivity pneumonitis induced by gold therapy was rarely reported in literature. But, the mechanism for the induction of the pulmonary disease is not blown. We report a case of seropositive rheumatoid arthritis presented as gold induced hypersensitivity pneumonitis which was confirmed by the peripheral blood lymphocyte stimulation test with gold.

PURPOSE: It remains controversial whether to use a tube graft or a bifurcated graft during open abdominal aortic aneurysm (AAA) repair, due to the potential for progression or development of a common iliac artery (CIA) aneurysm. This study evaluated the fate of CIA after tubular AAA repair. METHODS: On a retrospective basis, we reviewed 61 patients who underwent open AAA repair with a tube graft, between March 2000 and December 2009. Fifty-seven patients were included in this study; we excluded 4 cases in which the patients died in-hospital. Of those enrolled, 24 patients underwent follow-up computed tomography at least 1-year after surgery. CIAs were categorized into 3 groups: normal (< or =12 mm), ectasia (range, 13 to 18 mm), and aneurysm (range, 19 to 25 mm). The incidence of CIA aneurysm rupture was investigated, and the expansion rate of CIA was calculated. RESULTS: Mean patient age was 64 years and 73% of patients were male. Preoperatively, 8 patients had 2 normal CIAs, 14 patients had one CIA aneurysm at least, 27 patients had one CIA ectasia, and 8 patients were unknown. There was a mean follow-up of 51 months; no deaths were caused by rupture of CIA aneurysm, and no patient underwent invasive treatment for a CIA aneurysm. The mean follow-up for 24 patients with 48 CIAs was 45 months. The mean expansion rate of CIA was 0.5 mm/y. CONCLUSION: AAA repair using a tube graft was a safe and durable procedure. However, a bifurcated graft should be considered when patients are young and there is the expectation of a long life expectancy is anticipated allowing for a CIA expansion rate of 0.5 mm/y.

In situ follicular lymphoma is a newly defined entity among the lymphoid neoplasms and is defined as architecturally normal-appearing lymph nodes and other lymphoid tissues that have one or more follicles that demonstrate bcl-2 overexpressing centrocytes and centroblasts, with or without a monomorphic cytologic appearance suggestive of follicular lymphoma. Here we present a case of in situ follicular lymphoma diagnosed during the follow-up after a complete response to the treatment of lymphocyte-rich classical Hodgkin's lymphoma. In our case, because only a few germinal centers contained bcl-2 overexpressing cells, we missed the diagnosis of in situ follicular lymphoma in the initial histological examination. We could establish the diagnosis only after performing bcl-2 immunostaining in the sequential biopsy. Therefore, we recommend that careful histological examination along with bcl-2 immunostaining is needed in patients with suspicious clinical findings.

BACKGROUND: The mechanism of increased peritoneal permeability during peritonitis has not been clearly determined. We studied the changes in vascular endothelial growth factor (VEGF) levels in dialysate effluents during CAPD peritonitis, and VEGF expression in cultured peritoneal mesothelial cells (MCs) stimulated with IL-1 alpha, TNF alpha, and IFN gamma. METHODS: In 30 CAPD patients with peritonitis, dialysate effluents were serially collected at the time of diagnosis of peritonitis and when the peritonitis was recovered. Primarily cultured MCs were incubated with IL-1alpha or TNFalpha alone or in combination with INF gamma. VEGF level in dialysate effluent and MCs conditioned medium was measured by sandwich ELISA. VEGF mRNA expression was analyzed by Northern blotting. The activation of NFkappaB in response to IL-1alpha or TNFalpha was measured by electrophoretic mobility shift assay (EMSA). RESULTS: VEGF levels in dialysate effluent at the time of diagnosis of peritonitis were significantly higher (456+/-45 pg/mL) than those when the peritonitis was recovered (245+/-21 pg/mL)(p<0.00001). Both IL-1 alpha and TNFalpha stimulated VEGF production in MCs, and the stimulation was significant from 24 hours to 72 hours. INFgamma, in combination with IL-1 alpha or TNF alpha, significantly amplified IL-1 alpha - or TNF alpha - induced VEGF production. Pre-incubation of MCs with NF kappa B inhibitor, pyrrolidine dithiocarbamate, totally blocked IL-1 alpha - or TNF alpha-induced VEGF production. Northern blot analysis revealed that IL-1 alpha and TNF alpha stimulated VEGF mRNA expression in a dose dependent manner. The stimulation was peak at 4 hours. IL-1alpha and TNF alpha stimulated NFkappa B binding activity in MCs as early as at 15 minutes, with a peak activity at 1 hour, and p65 subunit was supershifted. CONCLUSION: Our results suggest that increased expression of VEGF in peritoneal mesothelial cells stimulated with proinflammatory cytokines, IL-1alpha, TNFalpha, and IFN gamma, plays a role in the increased peritoneal permeability during CAPD peritonitis.
