A 65-year-old female patient experienced melena for 10 days. Gastroduodenoscopy revealed a tumor in the duodenum, a portion of which was taken for biopsy, which showed a malignant tumor. She underwent pancreatoduodenectomy, and the final tumor pathology revealed invasive ductal carcinoma from the breast, which was confirmed using immunostaining of milk fat globule antigens. Nineteen years before, she had received a radical mastectomy due to invasive ductal carcinoma of the right breast. Hematogenous metastasis occurs in 33% of patients with breast cancer, mainly to the liver and lung, in invasive ductal carcinoma (IDC), and to the gastrointestinal tract, peritoneum, and retroperitoneum in invasive lobular carcinoma (ILC). Solitary metastatic duodenal tumors from breast cancer, especially IDC, is rare, particularly after a long time. This rare case is presented with a literature review.

BACKGROUND: There have been many changes to the social and medical environment in Korea and many studies showed a steady increase of cutaneous tumors. But none of them included a data occurring from head and neck. OBJECTIVE: To investigate the incidence and distribution of the cutaneous tumors of the head and neck. METHODS: A total of 1,415 cases of head and neck cutaneous tumors were obtained from pathology specimen at Department of Dermatology between 2010 and 2014. RESULTS: Among 1,415 cases of head and neck cutaneous tumors, 871 cases (61.5%) were benign tumors, 271 cases (19.2%) were malignant tumors, and 273 cases (19.2%) were premalignant lesions. The most common benign head and neck cutaneous tumors was epidermal cyst with 188 cases (21.6%), followed by 173 cases (19.9%) of seborrheic keratosis, 71 cases (8.2%) of intradermal nevi. Among the 271 cases of malignant head and neck cutaneous tumors, there were 164 cases (60.5%) of basal cell carcinoma, 89 cases (32.8%) of squamous cell carcinoma, 5 cases (1.8%) of malignant melanoma. The predilection sites of malignant head and neck tumors were face (87.5%), ear (4.8%) and neck (4.0%). Of the premalignant lesions, there were 210 cases (76.9%) of actinic keratosis, 36 cases (13.2%) of Bowen's disease and 27 cases (9.9%) of actinic cheilitis. CONCLUSION: In our study, the proportion of malignant tumors and premalignant lesion in head and neck tumors was higher than previous reports. Also, the percentage of woman in malignant tumors and premalignant lesions was higher than man, unlike previous studies. However, these results had limitation associated with retrospective study in a single institution, and further prospective study with multi-center is required for confirmation.

BACKGROUND: Elecsys 2010 immunoassay system is based on the electrochemiluminescence immunoassay using a ruthenium (II) tris (bipyridyl) label. Since it was the first time to use the system in our laboratory, we would like to evaluate the analytical performances (precision, linearity and recovery rate) and correlation with radioimmunoassay (RIA) and microparticle enzyme immunoassay (MEIA) methods. METHODS: We used precicontrol tumor marker (TM1, TM2) for alpha-fetoprotein (AFP), prostatic specific antigen (PSA) and carcinoembryonic antigen (CEA), Precicontrol universal (Ul, U2) for triiodothyronine (T3) and thyroxine (T4), Precicontrol-TSH for thyrotropin (TSH) and pooled serum for the evaluation of precision and recovery rate. Patients' sera were used for the linearity and comparison study. RESULTS: The coefficients of variatron of Imprecision study were below; 4.0%, 8.7% and 10.2%, respectively in the within-run, within-day and between-day analysis. The recovery rates were 100.5%, 96.1% and 102.5%, respectively in T4, TSH, and AFP. The linearity were y=1.02x-0.182(r=0.99) for T4, y=1.01x+0.12 (r=0.99) for TSH and y=1.01x+0.54(r=1.00) for AFP. T3, T4, TSH, CEA and PSA results showed good correlation with RIA (r>0.90), but AFP showed r=0.88. Also, AFP, CEA and PSA results showed excellent correlation with AxSYM (r>0.99). CONCLUSION: Elecsys 2010 immunoassay system showed excellent precision, recovery rate, clinically acceptable linearity and good correlation with the results obtained by RIA and MEIA methods.

Here, a case of a 59-year-old man with rotator cuff tear and impingement syndrome caused by an ossified coracoacromial ligament is presented. Ossification of the coracoacromial ligaments can occur because of degenerative changes due to trauma or repeated stress, which can lead to impingement syndrome. Therefore, when coracoacromial ligament ossification is present, rotator cuff damage due to impingement syndrome should be considered. Here, we conducted arthroscopic subacromial decompression, removal of the ossified coracoacromial ligament, and supraspinatus and subscapularis tendon repairs. We achieved satisfactory surgical outcomes without relapse; therefore, we report this case with a literature review.
