Adenomatoid tumors are well-recognized neoplasms generally to be of mesothelial derivation. We experienced a case of an adenomatoid tumor of the tail of the epididymis in a 56-year-old male. Grossly the tumor was firm and whitish gray, and microscopically it consisted of glandular, cord-like, microcystic structures which were lined by flattened endothelial like to plump cuboidal cells. Immunohistochemical stains whowed positivity for keratin and negativity for facter VIII related antigen and carcinoembryonic antigen. Ultrastructually, there was many long microvilli projecting into the glandular lumina and intracytoplasmic luminal spaces, desmosomes, and prominent cytoplasmic tonofilaments. Those findings strongly support the mesothelial origin of the adenomatoid tumor especially in the glandular type. It also lead us to suggest that the term adenomatoid tumor should be remain in use for light microscopic diagnosis, and that the term adenomatoid mesothelioma should be applied when the mesothelial nature of an adenomatoid tumor is proven by electron microscopy and immunohistochemical stains.

Background: Non-alcoholic fatty liver disease (NAFLD) is the most frequent liver disease. Evidence supporting a strong relationship between psoriasis and NAFLD exists. NAFLD is significantly higher in psoriatic patients than in matched controls and psoriatic patients with NAFLD have more severe forms of psoriasis than those without NAFLD. Objective: To evaluate the prevalence and clinical features of NAFLD among Korean psoriatic patients with abnormal liver function tests. Methods: We evaluated the laboratory results of psoriatic patients who visited the Department of Dermatology, National Medical Center, between September 2012 and June 2017. Those who had abnormal liver function tests were consulted by a hepatologist to confirm the diagnosis of NAFLD using ultrasonography. Results: A total of 307 psoriatic patients underwent liver function tests (LFTs), and 46 patients (15.0%) had abnormal LFT values. A hepatologist consulted psoriatic patients with abnormal LFTs, and hepatic ultrasonography was performed; 34 patients (73.9%) were diagnosed with NAFLD. Among psoriatic patients with abnormal LFTs, those with a Psoriasis Area and Severity Index (PASI) ≥10 had a significantly higher rate of NAFLD than psoriatic patients with PASI ＜10 (87.5% vs 59.1%). Conclusion Among psoriatic patients with abnormal LFTs, 34 patients (73.9%) were diagnosed with NAFLD.Psoriatic patients with PASI ≥10 had a significantly higher rate of NAFLD than those with PASI ＜10.

PURPOSE: The purpose of this study was to evaluate the effect of steroid injection according to the stage of Finkelstein's test and the severity of tenderness on radial styloid in de Quervain's disease. METHODS: Between January 2011 and December 2012, a total of 57 patients (57 wrists) treated with steroid injection in de Quervain's disease were enrolled on this study. The severity of tenderness, the stage of Finkelstein's test and pain score using visual analogue scale (VAS) were assessed before steroid injection. And the effect of steroid injection was assessed until one year after steroid injection. The relationship between the recurrence of de Quervain's disease after steroid injection and pre-injection findings including tenderness, Finkelstein's test and VAS was assessed. RESULTS: The success rate of steroid injection was 71.9% (41/57 patients). The outcome of steroid injection was not significantly related to the severity of tenderness (p=0.648), the stage of Finkelstein's test (p=0.530) and VAS score (p=0.607). CONCLUSION: The tenderness on radial styloid and the Finkelstein's test are important physical findings for the diagnosis of de Quervain's disease. However, the severity of tenderness and the stage of Finkelstein's test were not showed as predictive factors for the outcome.

Adenoma malignum (minimal deviation adenocarcinoma) is an extremely well-differentiated adenocarcinoma of uterine cervix. Despite its benign histological appearance, this tumor is thought to be malignant and has a poor prognosis. Because Pap smear and punch biopsy have low sensitivity, accurate diagnosis of the tumor may be difficult. If it is diagnosed, it must be treated same as in cervical cancer. We presented one case of preoperatively diagnosed adenoma malignum by deep cone biposy with a brief review of literature.

PURPOSE: The purpose of the present study was to assess the biological effects of TNF-alpha in Caco-2 well-differentiated colon adenocarcinoma cells and to determine radiation sensitivity in order to develop TNF-alpha into a cancer therapeutic agent. MATERIALS AND METHODS: A cell viability test was conducted via a colorimetric and colony forming assay after 1 day and 3 days of incubation with TNF-alpha. Western blotting analysis and immunofluorescence staining were conducted to explore TNF-alpha-induced morphological and molecular changes in the adhesion molecules, E-cadherin and claudin-4. The effects of gamma-irradiation at a dose of 2 Gy on cell survival were evaluated by a clonogenic assay. The molecular changes in apoptosis-regulatory proteins were assessed by Western blotting. RESULTS: Caco-2 cells were highly resistant to TNF alpha-induced cell death and 2 Gy of gamma-irradiation. However, we observed the downregulation of the adherens junctional protein, E-cadherin and translocation of tight junctional protein, claudin-4 from the membrane to the cytosol induced by TNF-alpha treatment which would indicate cell-cell junction disruptions. These alterations of junctional proteins influenced the regulation of cell death in response to 2 Gy of gamma-irradiation. The combined treatment of TNF-alpha with 2 Gy of gamma-irradiation reduced the survival of Caco-2 cells by down-regulating bcl-xl and activating JNK pathways. CONCLUSION: These results suggest that TNF-alpha might be potentially applied as a therapeutic agent in order to enhance sensitivity to 2 Gy of gamma-irradiation administered in radiotherapy for the treatment of human colon cancer.
