Ascending Colon Cancer with Pathologically Confirmed Tumor Thrombosis of Superior Mesenteric Vein: A Case Report.

Colon cancer is very rarely accompanied by tumor thrombosis of the superior mesenteric vein (SMV). A 46-year-old patient had been diagnosed with SMV tumor thrombosis related to colon cancer without hepatic metastasis and underwent right hemicolectomy with SMV tumor thrombectomy. Tumor thrombosis was pathologically confirmed as metastatic colon cancer. There has been no recurrence for 12 months with 12 cycles of adjuvant-chemotherapy.

The Behcet's Disease Quality of Life: reliability and validity of the Korean version.

PURPOSE: The Behcet's Disease Quality of Life (BD-QoL) is a BD-specific measure developed in the UK. The aim of this study was to adapt the BD-QoL for use in Korea. PATIENTS AND METHODS: The translation was based on the guidelines for cross-cultural adaptation. A total of 201 Korean patients with BD participated in this study. To evaluate the psychometric properties, internal consistency and test-retest reliability were used. Factor analysis was performed to examine the construct validity. To provide further evidence for validity, the correlation of BD-QoL with the Clinical Activity Form for Korean Patients with BD (BDCAF-K) and the Center for Epidemiologic Studies-Depression (CES-D) scales was assessed. RESULTS: The Korean version had high internal consistency (Cronbach's alpha, 0.93) and test-retest reliability (r = 0.835). Factor analysis of the questionnaire revealed one interpretable factor as a general health-related quality of life factor. The Korean version significantly correlated with scores of CES-D (r = 0.749, p = 0.000), self-rating scale of well-being over the past 28 days (r = 0.446, p = 0.000), and BDCAF-K score (r = 0.502, p = 0.000). CONCLUSION: Adaptation of the BD-QoL for use in Korea was successful. Together with the BDCAF-K, it may be a valuable tool for assessing the influence of interventions in BD patients and outcome in clinical trials.

Erythema nodosum: clinicopathologic correlations and their use in differential diagnosis.

PURPOSE: Typically, a diagnosis of erythema nodosum (EN) is based on clinical features. However, other diseases manifest with inflammatory nodules of the lower limbs in addition to EN, such as the EN-like lesions of Behcet's disease (BD). The purpose of this retrospective study was to investigate the frequency of histologically proven EN among diseases diagnosed clinically as EN, to determine underlying causes of EN, and to compare clinical and histologic features between EN and other diseases. PATIENTS AND METHODS: We selected 99 patients diagnosed clinically with EN and performed skin biopsies. All pathologic slides were evaluated and diagnosed; and after histologic diagnoses were made we reviewed the patients' medical records. RESULTS: Among the 99 patients diagnosed clinically with EN, 47 were biopsy-verified EN. The EN-like lesions of BD and nodular vasculitis were both in the primary differential diagnosis of EN. No definite difference in clinical features exists among these three diseases. Histologically, EN demonstrated septal panniculitis in the majority of patients. Lobular panniculitis was frequently observed in NV, and mixed or mostly lobular panniculitis was observed in the EN-like lesion. Vasculitis was rarely observed in EN; however lymphocytic vasculitis was observed frequently in EN-like lesions and neutrophilic vasculitis was observed in NV. The frequency of granulomatous inflammation was highest in NV. Some cases of patients with typical BD demonstrated classic EN lesions. CONCLUSION: It was extremely difficult to clinically differentiate EN from EN-like lesions or NV. We feel skin biopsy is mandatory for the diagnosis of lower extremity erythematous nodular lesions.
